The Tacticool22 Bayonet Barrel Adapter prevents a bayonet from rattling around on your rifle’s barrel, and works on 16″ barrel AR-15’s with carbine length gas systems.
At less than an ounce, this 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.
Bayonets that will work include the M7, M9, M10, M11, and USMC OKC-3S.
Note: You will need to purchase the crush washer separately.
Note: It is your responsibility to review and follow all United States of America federal, state, and/or local laws and regulations related to the use, possession, purchase and/or ownership of restricted items. And of course, be safe and have fun.
