TECH TIP: Large Pin AR or Small Pin AR

Large Pin or Small Pin?

  • Large Pin Colt
  • Mil-Spec Colt
  • Small Pin Colt
  • Mil-Spec AR-15
  • Colt AR-15 Large and Small ~ Hammer and Trigger Pins

Some civilian Colt AR type rifles were manufactured with hammer and trigger pins and holes which are .170 inches in diameter. These are referred to as Large Pin Colt receivers. This was not in all Colt models, just some.

All other AR type rifle manufacturers have used the military specification .154" diameter hammer and trigger pins and holes, or small pin.

Ar_15/ar15_trigger_pins.jpg

The only way to know for sure is to measure your pins or the holes in your lower receiver to determine if you have a small pin or large pin Colt receiver.

If you are building a Kit Rifle with a Stripped Lower Receiver and a Parts Kit, or own a Factory Built Rifle, Our AR-15 Shims are Easy for Novice or Expert alike to Install.
If you are doing a AR-15 Trigger Job, or installing a Trigger Kit, add our shims to take out the slop and stop parts from rubbing.

Ar_15/ar15_trigger_shim.jpg

This is the AR-15 Trigger and Disconnector Assembly
with an AR-15 Trigger Shim Installed to show size.
Our Trigger Shims will fit the Trigger, Hammer and Disconnector of most
Small Pin AR-15 Style Rifles.
Care must be used when installing to insure no binding is present

Ar_15/ar15_hammer_shim.jpg

AR-15 Trigger Shim Installation Instructions
Remove Magazine and Open Chamber, Make Certain Gun is Unloaded!
Remove Take Down Pins and Separate Upper from Lower Receiver,
Set Upper Aside.
Remove Hammer Pin and Remove Hammer.
Remove Trigger Pin and Remove Trigger.

Now Remove the Springs from the Hammer and Trigger, including the Disconnector Spring and set aside.
Set the Disconnector aside.
Now you can Re-Install Your Hammer and Trigger Without the Springs and Install Shims to Check for Clearance.
This is necessary to Make Certain there is No Binding or Sticking of the Trigger and Hammer.
Remove Pins and Hammer and Trigger, Install Disconnector without Spring into Trigger, add Shims, install Trigger Pin and check for proper clearance and free movement of the Disconnector with shims installed.
Again, you must be absolutely certain there is no binding and the Disconnector Moves Freely.
There is Normally Very Little Clearance between the Disconnector and Trigger, and may not need to be shimmed, or you may just want to skip putting shims in there all together.
In Order to Shim the Disconnector you will need to use a Cheater Pin, Reassemble the Disconnector and Shims and Spring into the Trigger as a Sub-Assembly.
ReInstall the Trigger into the Lower Assembly now that you are Assured the is No Binding Caused by Adding Shims, Once the Trigger Assembly are Installed, it is a Simple Matter to Install the Shims.
Simply Push the Trigger Pin out just enough to slide a shim Between the Housing and the Trigger.
A Little Gun Oil on the inside of the Lower Housing will Allow the Shim to Stick and Slide Easily with a Tooth Pick into Place, working the Trigger Assembly to Align Shim, slide the Trigger Pin Back into Place.
The Hammer and Shims can now be Installed in the Same Manner.
Be Sure Again to Check Your Work for Free Movement and No Binding on Trigger/Hammer Parts.
Safe Operation is your Sole Responsibility, if you have any question, have it checked by a Competent Gunsmith.

Special Size Sear Shims are needed in the Geissele Enhanced Triggers designed for mil-spec AR15/M4 carbine rifles

The Casting of the Geissele Trigger is not quite deep enough in the Sear area for my standard AR-15 Mil-Spec Trigger / Sear shims to fit the Sear, so I made a special slightly smaller OD shim for the Geissele

Lance, Your product (Pivot Pin Shim) is fabulous!
My AR is nice and snug now without the use of the polymer wedge inside.
I’m absolutely thrilled and have already ordered more of your shims.
Great work and I’ll sing your praises on the forums I frequent.
Thanks, Randy P.

Thanks for your quick response, Lance. You do make an excellent product. I've found that I can lightly sand the shim and pivot pin area with 320 wet & dry, clean with naptha or alcohol, and use Dap Rapid Fuse to adhere the (Pivot Pin) shim to my rifle. - Robert in FL

I received my purchase today thank you for your prompt service. So I was online looking for a smarter way to take a little of the wobble out of my upper and lower and I came across your video on the shims for a cop / muzzle brake just so happened I needed some so I went on so I went on your site to get them and what did I find a smarter way to take the wobble out of my upper and lower so I also purchased the pivot pin shims. God works in mysterious ways, Thanks Again I'll be sure to keep your information. - Matt in NM

TECH TIP: AR-10 Pivot Pin Shim Demonstration
by Sgt Vance


Lance, Thank you for your wonderful service. The shims arrived yesterday and I installed them this morning. The difference is night and day, groups that were 2 1/2 inches at a hundred yards went to 3/4 of an inch at a hundred yards. Thank You Again for this little miracle device. Joe in PA

Lance,
I just got home and I installed one .002 shim and one .003 shim on the front takedown pin
and it cured the looseness/wobble between my upper and lower. Wow, you have a great product there guys!
Thanks, Don in Knoxville, TN

Hello Lance, I had no idea just how effective shimming my upper would be. Prior guns I've built with an Aero Precision upper and Spike's Tactical lower usually have a pretty good fit, but this particular combo required a .005 and .004 shim to remove all the slop. Sure, I went in expecting an improvement. But what I got was nothing short of jaw dropping. No play whatsoever yet the gun still opens smooth as silk with zero binding of any sort. Amazing improvement. I'm now going back and shimming all my other ARs so each is equally perfect. Glad I bought the big pack. You rock! Kevin

Lance,
Got your shims in today. I have a Palmetto State Carbine with a 12 inch free float hand guard. I'm attaching shots of the pivot pin up close with your shims installed. I had to use one .002" shim and one .003" shim to get it just right. It was not the easiest to install but the effort is well worth it. Now the upper to lower fit is rock solid with still smooth operation when opening the rifle. I will try my best to never remove the pivot pin to avoid having to re shim. Excellent product, super fast shipping, incredibly satisfied. Very precise product. Thanks! ~ Jimmy D.


Hi Lance, Just wanted to let you know I'm very happy with my Front Take Down Pins Shims (Item# AR-15 PPSP) I ended up using a .003" shim on each side, and now the upper on my precision AR doesn't move from side to side. The shims were nicely packaged too. Thanks for a Great Product and God Bless You and Your Family ~ D.R. in VA

Lance, Just wanted to let you know I installed the shims today and they worked out perfectly and my upper is now really solid. I will definitely recommend you to anyone I know who is putting an AR together. Thanks very much, Jacob in MA

Customer Testimonial on our AR-15 Pivot Pin Shims;

Hello Lance,
I received my package of shims this week, shipping was fast, packaging and parts are in pristine condition.
I couldn't be more satisfied to purchase this assortment of AR-15 pivot shims. The option of three different sizes allows you to fit correctly. As a bench rest shooter I am confident these shims will eliminate the variance in my upper receiver. This is really a hard to find item and is a quality upgrade. It was a pleasure to do business with TriggerShims.com
Thanks.... Jim in Michigan

Small ID Pivot Pin Shims

Joe writes;
I need a AR-15 Pivot Pin Shim to fit the Cross Armory Pin Pal

I looked into it and found Cross Armory manufactures an ingenious little device to replace the Front Takedown Pin.
Apparently in the heavily gun regulated states where elected officials don't believe in our Great American Constitution, AR-15 owners are now opening their receivers with great frequency.......
I guess it is because of the "Fixed Mag"

Anyway, their new design front pivot pin device requires an new size AR-15 Pivot Pin Shim,
and since I am The Shim Guy, I manufactured them.

Introducing the 3/16" ID AR-15 Pivot Pin Shim #AR15SIDPPS or

With the same OD as a standard AR-15 Pivot Pin Shim, and a .189" ID,

BOX#AR15-Wedge

Accu-Wedge for AR-15 / M16

Made in the USA

Accu-Wedge

Drop-In Accuracy Fix; Stops Unwanted Movement Between Receiver Halves
Can be used in combination with our Pivot-Pin Shims.

One of the fastest, easiest, cheapest accuracy-improvements you’ll ever find for your AR! Tough, high-density synthetic rubber wedge drops into the space behind the rear takedown pin in the lower receiver to provide tension between the receiver halves and prevent movement for improved accuracy. Takes the “loose gun” factor out of the equation, so you shoot tight, consistent groups. Can be trimmed to accommodate any variation in upper-to-lower receiver fit.
And Made in the USA!

Sorry, we no longer stock these, order directly from Brownells

The "Poor Man's" Trigger Job

JP Ent AR-15 Springs

Spending $140 or more for trigger parts on every AR-15 rifle you may own may not be realistic. If you can't quite pop for a JP Enterprises complete trigger kit, or have too many rifles and can't justify expensive triggers in all of them, then this may be for you. You can achieve a significant improvement over stock parts by using a set of JP custom trigger/hammer springs. With proper sear and hammer notch preparation, a livable 4.5 to 5.0 smooth trigger in a rifle with standard trigger components is possible. It will not have the extremely short engagement/over travel feel like the JP trigger, but you will have a smooth "roll-off" feel that will give usable trigger control. The spring kit includes trigger, hammer and disconnector spring and complete instructions on how to prep your parts for best results

Note: Use of this spring kit requires the use of US manufactured (domestic) ammunition or reloads with domestic (non-NATO spec) primers as ignition reliability will beJPS3.5 Tag reduced with hard low sensitivity primers as found in made foreign made ammunition's and NATO specification ammunition. Use these parts only in rifles for recreational or competition shooting. Do not use this spring kit for any defense or duty applications or any AR-10 type rifle.

One geometry change was moving the hook .015" closer to the rim and changing the angle so that it grabs the spent casing with much more precision and control. The extractor is A2 Tool Steel and hardened to Rc 58~~60 so this extractor will not wear out or round over after years of use.

AR-9 EPC Carbine
AR-9 Carbine

Watch this Box for My New Article on AR-9 Blowback / EPC-9

The Pistol-Caliber Carbine has been around for a long while. A broad definition is a Rifle that shoots Pistol Ammunition. The 1873 Winchester Repeating Rifle was one, chambered in .44-40 Winchester it was known as "The Gun That Won the West"
The .44-40 was also popular revolver cartridge used in the Colt SAA Revolver, Remington and others.

Fast Forward 150 Years and the rifle I am interested in building is an AR-15 chambered in 9MM, the AR-9 or Enhanced Pistol Caliber - 9 or EPC-9

For several years I have been hesitant to build an AR-9 because each time I got an itch to do it, I found many people who had problems with, so I held off.
Early on malfunctions seemed to be a fact of life with this gun, and that did not interest me since I prefer my self defense weapons to operate flawlessly when needed, and not be fancy, two reasons I carry a Glock
This year I again got interested in an AR-9, and started researching what was new when I found the guy who made my hesitation go away, Doug at Blowback9.com Blowback9.com
After spending several enjoyable hours reading Doug's articles and watching his videos, I started shopping for and gathering parts for a 9MM Pistol Caliber Carbine

After a lot of online shopping, I found B. King's Firearms had all the parts I needed and at very reasonable prices to boot.

I bought almost all the parts I needed for this build at B. King's Firearms in Lima Ohio. I do not have a Dealer Account with them, and the consumer pricing was great across the board on everything I purchased, the shipping was very fair and fast. I am not affiliated or have a monetary interest in BFK, I recommend them because I am a Very Satisfied Customer, you can find them on my Links Page, tell them TriggerShims sent you!

The only part I bought elsewhere was the serialized lower receiver, which I caught on sale at Brownell's.

My First Chore - Compile a List of Parts

This is the fun part, researching and buying the parts. I pretty much followed Doug at Blowback9.com and his recommendations on key parts,

Important dedicated 9mm parts:

  • Aero Precision EPC-9
  • BKF 9mm AR Bolt – Nitride
  • Ballistic Advantage 16″ EPC 9 Barrel
  • KAK Industry Micro 1/2-28 “Slim Line Flash Can”
  • KVP 10oz 9mm Tungsten Blowback Buffer - this is the BIGGLY, more on that later
  • My List of Standard AR Parts

  • BKF AR15 15" M-LOK Handguard
  • BKF AR15 Billet Charging Handle
  • BKF M4 MOD-0 Assembled Upper Receiver - Black
  • BKF AR15 Receiver Extension Castle Nut
  • BKF M4 Mod-0 Lower Parts Kit (LPK)
  • BKF AR15 Lightweight 8 Position Anti-Tilt Carbine Length Buffer Tube
  • BKF Ar15 Nickel Teflon Reduced Power Fire Control Group - Complete (Polished) (3.5lbs-4.5lbs)
  • BKF AR15 Carbine Buffer Spring Mil Spec 17-7 Stainless Steel
  • I tried to stick to standard AR parts when ever possible. My way of thinking is to keep as many standard parts on hand, and only use specialized EPC-9 parts when I felt it was necessary.
    You may find the Aero Upper/Lower combo is the way to go, especially because the upper has a dedicated EPC-9 Bolt Hold Open that a standard AR-15 Upper will not.
    A friend of mine is a dealer for Aero, so if you are in the market for the Aero Precision EPC-9 Receiver Set and live in western lower Michigan area give Dana a shout at Summit Tactical sales@summittactical.us - They do transfers too.

    After I had received all my parts I started the assembly, I am not going to do a step by step video or write a long detail article, there are plenty of good videos and manuals on the internet, I am just going to tell you what my thoughts were on the whole project..... Two Thumbs Up!
    All the parts went together flawlessly, the BKF M4 MOD-0 Assembled Upper Receiver fit the Aero EPC-9 Lower Receiver like a Matched Set, with no room whatsoever to install a TriggerShims.com Pivot Pin Shim (a small super thin washer that takes up space when an AR Upper and Lower are loose at the joint.)

    Every part I bought from BFK fit like a glove, considering I bought the AERO Lower from Brownells, and the BFK MOD-0 Upper, I couldn't be happier with the fit.

    Hi Lance, I built one of these CMMG dedicated uppers on your suggestion. I did not want to neuter the M&P carbine lower I built, a rimfire let’s me keep the look. I am very pleased with this gun and the accuracy. I have plenty of accurate bolt 22’s, and love my Anschutz and M-52; but like you, it is my favorite play gun at the range. Thanks for the suggestion ~ Joe

    Dedicated Upper AR-15 .22 Build

    Let me tell you about an AR-15 .22 LR Dedicated Upper I built with parts here at TriggerShims and from Brownell's through the links on this page.
    The conversion kit was made by CMMG and is available in several different configurations.
    I chose the CMMG Stainless Steel .22 LR Kit because the reviews I read said it didn't require any Break-in Time, and besides, I am a sucker for Stainless Steel.
    The kit I have is the Bravo Model SS Conversion Kit with 25 Round Magazine, there is an Alpha Model in Black Phosphate, and an Echo Model in SS with Forward Assist.
    I decided to build a complete Upper Assembly with a Dedicated Barrel, DPMS Flat Top Upper Receiver, Leapers Full Float Tactical Handguard, Leapers Quad Rail Gas Block, (both available above on this page) and cap it off with a DPMS A1 Flash Hider. I like the A1 Flash Hider simply because it is simple, no timing/clock positions to worry about.
    And cheap, you can pick one up for under $8 at Brownell's or at most any Gun Show.

    Brownell's has a lot of AR-15 Stripped Upper Receivers to choose from, some as low as $50 and still excellent quality. I went with a USA Made DPMS A3 and added a forward assist and Ejection Port Cover.
    Precision machined from a premium-grade aluminum forging and hardcoat anodized for extra strength, with a tough, scratch-resistant Teflon coating, I know DPMS makes quality products, or I wouldn't recommend them.
    Brownell's also carries USA Made Receivers from Colt to Aero, Brownell's own brand and others.

    CMMG - AR-15/M16 22LR DEDICATED BARREL

    I have to admit two things, first, shopping for the parts to assemble this gun was a lot of fun, and second, every time I shoot it I grin like a little kid!
    There are a host of very nice AR-15 .22 clones on the market, from the Umarex Colt M4 OPS I saw at Cabela's for $499 on sale to the Mossberg Clone .22 Rifle at Walmart in the $225 range.
    The reason I wanted to go with a Build was I could choose my own combination of parts, I enjoy the planning and shopping, and the sense of accomplishment in having it turn out as planned.
    I could have just added the CMMG .22 conversion to my .223 upper, but I wanted a dedicated .22 barrel and the M4 Contour CMMG AR-15/M16 Dedicated .22 LR Barrel looked like a very nice barrel for the price, with the promise of better accuracy with the 1 in 16" twist rate common in .22 LR rimfire rifles.

    How To Build an AR-15 .22 Rifle Parts Picture

    You can see in the picture here to the left all the parts I used to build my .22 Rifle Upper,
    the CMMG conversion kit came with a chamber adapter for a .223 barrel, (not shown) and the CMMG barrel came with an adapter for .22 which I have changed out on the bolt in the picture.
    Since I sold off my old upper, I didn't have any parts to reuse, so I had to purchase all the parts here in this picture. You may want to re-purpose some of the parts you have on your .223 cal upper, and that is the great part of this build, all the parts are interchangeable with standard mil-spec AR-15 parts.
    If you are using a .223 upper, the barrel gets replaced, the gas tube gets removed, and the bolt gets replaced with the conversion bolt.
    If you are building from the ground up as I did, consider our Leapers UTG Free-Float Quad Rail System for sale above.
    By using the Free Float Quad Rail, you will not need a Delta-Ring Assembly or a HandGuard Cap.

    You will also need a Front Sight or a Gas Block, not for gas in this case but rather to mount your front sight to.
    The CMMG Barrel is not cross drilled for an A2 Front Sight, and I wanted a gas block anyway since I was planning on using optics and could always add a clamp-on flip-up fromt sight later.
    The Leapers UTG Quad Rail Gas Block I can recommend without hesitation. Strong with Excellent Machining and a great Hard Anodized finish, it fits .750" barrels and has 2 set screws instead of one like many have, and it too is Made in the USA!

    USA Made AR-15/M16 UPPER RECEIVER ACTION BLOCK

    Next, we will be discussing the tools you will need to assemble your AR-15 .22 Rifle conversion.

    AR-15 Tools    -Click to Enlarge-

    To install or remove a Barrel from a Receiver, you will need an Upper Receiver Action Block. I bought the Brownell's AR-15 Action Block

    The Brownells Upper Receiver Action Block as shown in the picture, and have found it to be sturdy and very satisfactory. The Heavy Duty Blocks surround your Receiver inside and out so you can firmly clamp it in a vise without risk of crushing, twisting or distorting it. I use hardwood blocks in my vise to protect the Action Block from damage from the knurling in the vise jaws.

    USA Made AR-15/M16 COMBINATION WRENCH

    You will also need some kind of wrench, there are many on the market with so many configurations it's like buying a Swiss Army Knife, but for this job you really only need a basic AR-15/M16 Combination Wrench.
    Installing the barrel is easy and straight forward. First, Lubricate your receiver threads with a good grease or anti-seize,
    I like Rig Universal Gun Grease, and I put a light coat inside and out of the receiver threads, barrel nut and barrel extension.
    The Barrel Nut needs a minimum of 35 ft lbs of torque, and up to a maximum of 80 ft lbs, so somewhere between those points we need to line up our gas tube holes.
    The conversion barrel doesn't use a gas tube, but the Free Float Hand Guard depends on it's alignment for proper alignment of the rails.
    After installing the barrel nut, the Full Float Quad Rail slides on and is held in place with 4 screws included in the hardware kit.
    Make sure to put a drop of Blue Locktite on the screws and snug down evenly.
    Slide the Quad Rail Gas Block on the barrel and level it to the upper receiver, put a drop of Locktite on the clamp screws and snug them down too. Last, install the A1 Flash Hider, use a Barrel Vise or Hardwood Blocks in a vise and lightly tighten it on the barrel.
    Install the Charging Handle and CMMG Bolt and you are ready to mount the Upper Receiver to the Lower.

    I have had this gun for a year now, and I wanted to do this video to show how easy it was to assemble a Dedicated .22 Cal AR-15 Upper.
    The CMMG Conversion has worked flawlessly for me and the CMMG WASP Barrel is quite accurate. The whole thing is topped off with a Rimfire Optimized Nikon P-22 2-7X32 with BDC 150 Reticle that not only looks good with the matching AR Platform Rings, but is clear and easy to use.
    I have had so much fun with this gun that it has achived Favorite Gun Status in my book.
    If you talk to the folks at CMMG or Nikon, tell them Lance sent you, and I Promised that their products would not disappoint.

    Lance and Tammy,
    I just wanted to say THANKS for the AR-15 Take Down Pivot Pin Shim Kit. It completely eliminated the play I had. You saved me a lot of time and prevented me from buying a new upper or lower. The Blue .003 shim fit perfectly. I'll recommend you on the YouTube videos and forums about the wobble most people don't like, and how to fix it. The rubber O ring "trick" seemed to work, but once you look inside they are broken. (I tried many sizes)
    Live long and prosper, Sean

    Hi Lance, Well I got the shims today and already shimmed my rifle. I gotta say it was easier than I thought it was going to be. I'm not colored blind but it was tough telling the difference between the orange and red shims lol! But if I were to purchase these again I would definitely get the 50 pack. The .0015 shims would've came in handy and also you may lose or damage some in the process so it was nice to have more than what i needed. I would recommend using just a little bit of grease to help the shims stick to the upper. The gun is now tight and no more rattle. I couldn't be happier. A very good investment if the rattle drives a guy insane! ~ Corey in WI
