KAK Industry Plan B A7 Flash Hider 1/2x28 Nitride, 17-4 Stainless, Plan B Compatible 410-2103-006
Product Description
The KAK Industry Plan B A7 Flash Hider is a Plan B-compatible muzzle device engineered with a taper followed by threads to promote repeatable lockup and a proper seal between the muzzle device and suppressor adapter. Built from durable 17-4 stainless steel with a nitride finish, it is designed for .223 to 9mm applications and features milled rear flats for straightforward installation without timing. For best results, KAK recommends installing with Rocksett and tightening to 20–25 ft-lbs of torque. Note: some suppressor manufacturers may not honor warranty claims when using other brands of muzzle devices.
