AR-15 Bayonet Muzzle Ring Sleeve (Barrel Adapter)

Price Match Guarantee

Bayonet muzzle ring too big? The Tacticool22 Bayonet Muzzle Ring Sleeve—also known as our popular Bayonet Barrel Adapter—allows the muzzle ring in the cross guard to fit properly which prevents the bayonet from moving around excessively.

Product Description

At less than an ounce, this AR-15 bayonet barrel adapter is very lightweight, and fits standard 3/4″ barrels with 1/2-28 threads, such as the S&W M&P15 in .223/5.56. It is also easy to put on. Just remove your flash hider and crush washer, slip on the adapter and add a new crush washer, and then screw on your flash hider or other muzzle device.
