Tightens Receivers Rock Solid, Improves Handling, Helps Accuracy, Slows Wear.

Overview... An AR15AccuShim presses easily into the upper receiver recess/sear relief located next to the takedown pin lug. The shim supports the sides of the receivers and eliminates slack and wobble without altering the original takedown pin configuration. The shim is gradually surfaced by hand until the takedown pin fits snug for target shooting or reduce thickness more for quick and easy pin removal, either way the receivers will feel tight and right. Installation involves removing rail mounted accessories. Tools needed: caliper, screwdriver and pliers.

Will the shim work in your rifle? Visually verify the chamber is cleared. Open the receivers, remove the charge handle and bolt carrier group. If present remove the polymer AccuWedge. Lay a blade type .012" automotive feeler gauge across the lower receiver above the safety lever. Close and hold the receivers together firmly. If the takedown pin resists any when pushed or finds resistance passing through the receivers means the shim should work. If the pin passes through with no resistance means the shim may not work. Depth for the upper receiver recess/sear relief should measure .090" Width .750" - .755".

Remedies for receivers that gauge too loose...Replace pivot and takedown pins measuring under .248" diameter. Upper and lower receiver pin bores should be close to .249" - .250" diameter. Pin bores measuring .250" can be fitted with oversize Armalite NM Pins, etc. The takedown pin lug bore in many upper receivers is an approximate .250" x .260" slot machined to align with various lower receivers, measure vertical wear. Gauge receivers for shim compatibility, replace out of spec components and install an AR15AccuShim.

Installation/Fitting Requires Gunsmithing Skills. Average First Installation Time 30 - 40 Minutes, Additional kits average install 15 - 20 minutes.
