AR-15 Barrel Nut Shims - 10 Pack
.223 Barrel Nut Shims are a great compliment to any .223 Free Float Quad Rail. If your forearm doesn't have the ability to "time" the position of the forearm in relation to the gun, this shim will give you this capability. This 0.19mm shim fits between the barrel nut and upper receiver to allow the user to adjust the relationship between the gun and the forearm features like swivel studs, vent openings, and Picatinny rails, to the shooters' needs.
10 per pack
Will fit .223, 7.62x39, and Blackout AAC 300
Won't fit .308
