American Made Gun Shims

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.

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.

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 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.

Read This Review from Zach:
Lance - I had a hell of a time getting the AR-15 Trigger Shims in there with the drop-in trigger, but I couldn’t more satisfied!
You are the only person I could find with this product and while it may not be necessary for the rifles function I absolutely love that trigger now has zero side to side play in it. Makes the rifle feel much better and of higher quality. I will 100% be ordering more for future builds and recommending your site to all my friends.
Thanks a Lot! - Zach in UT

Geissele AR-15/M4 Sear Shim

Geissele Automatics Special AR-15/M4 Sear Shim

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

This Shim can be used Both for the Trigger and Sear, but the Smaller OD was made Specifically for the Geissele Automatics Trigger Sear

Lance - I wanted to thank you for making these for my Polymer Lower Receiver. Ed in Idaho

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

made specifically to fit the Cross Armory Pin Pal.

BOX#AR15-Wedge

Accu-Wedge for AR-15 / M16

Made in the USA

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

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 complete drop in 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 trigger/hammer springs. With proper sear and hammer notch preparation/polishing, 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 high price trigger, but you will have a smooth "roll-off" feel that will give usable trigger control. Many spring kits includes trigger, hammer and disconnector spring and you can find my online video instructions below

I have installed and had great success with the BKF Ar15 Nickel Teflon Fire Control Group – Complete (Polished) under $50 or you can go with the standard finish BKF AR15 Reduced Power Fire Control Group (Polished) (3.5lbs-4.5lbs) for under $30

There is a nice selection of trigger parts at B. King’s Firearms, I do not receive any stipend from recommending King's, I recommend them because I have bought from them and found their parts and service very good.

Volquartsen Exact Edge Extractor ~ VC15EE

VC15EE Exact Edge Extractor for S&W M&P 15-22

Proudly Made in the USA

Exact Edge Extractor for the Smith and Wesson M&P 15-22. The replacement extractor was manufactured through a EDM process to provide exact tolerances. The geometry has been changed to provide positive ejection every time. 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.

Solves Jamming and Stove Pipe Issues

AR-9 EPC Carbine

AR-9 Blowback / EPC-9 with Glock Magazines

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.
I have always been a big fan of the Old Wild West, but in modern times I wanted my carbine to be something I was more comfortable with than my Dad's old Lever Action.

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 own several Glocks
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
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.
A Big Shout Out to Doug, without his guidance this project would not have been a success.

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 located in the Nice Town of Lima, Ohio where he does business and has a showroom, warehouse and weapon system manufacturing center. Just off the I-75 Freeway East on Findlay Road, it is very easy to find.
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 BKF, 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 where I do have a dealer account.

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:

My List of Standard AR Parts

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.

~ Does it shoot? ~

So, how does it shoot? I am more than happy with it, I have not had a single FTF or FTE, it runs smooth and is accurate, the recoil is kid friendly, and the noise is very tame.
In short, shooting it makes me smile ;-)

Any Questions, let me know, God Bless America and Good Shooting, Lance

Update: I am rethinking the barrel and handguard combination,
though it is center balanced, it feels a little nose heavy, I will be looking at a lighter contour barrel like this ~ Bear Creek Arsenal 9MM Barrel

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.

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.

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.
