Tramming an AR Upper/Lower?

The APG Shim Kit is here! My kits include 3 sets of shims that fit most common tolerance differences, a brass tipped upper tension set screw, and all the materials necessary to install the shims on your rifle or pistol.

The process is easy and requires little skill to install the shims. The APG shim kit is the first step in harvesting the true precision potential of your rifle. I have even included a FREE installation video to see you through your efforts; All that you need to do is add the kit that most suits you to your shopping cart!

APG Shims are made in the USA, under strict tolerances and are composed of the finest American alloy steels available. All profits from the APG kits go to fund the research and development of cutting edge gunsmith tools. Proceeds will also fund my gunsmith how-to videos on YouTube.
