AR-15" Colt AR-15 Hammer and Trigger Large and Small 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 clearence and free movement of
the Disconnector with shims installed. Again, you must be absolutlely 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 Responsiblilty, if you have any
question, have it checked by a Competent Gunsmith.

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
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.
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!

The "Poor Man's" Trigger
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
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 be 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.

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 Upper Receivers to choose from, 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 Armalite to Wilson Combat and a new offering from Brownell's, the Laser Etched Flattop Upper available with many Laser Etched logo's including the sought after "Zombie Hunter"
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 Barrellooked 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 we sell 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!
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
use 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. 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 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. If you enjoyed this
