KAK Industry PLAN B Big Hole Endplate Black 1/2x28 – 5.56/.223/9mm Suppressor Mount

The KAK Industry PLAN B Big Hole Endplate is a minimalist muzzle device designed to serve as a direct-thread mount for compatible suppressors. This endplate-style device eliminates the need for traditional flash hiders or brakes, creating a flush mounting surface that keeps your suppressor tight to the barrel. The big hole design accommodates full-bore passage for reliable function with both .223/5.56 and 9mm projectiles.

Machined from steel with a black finish, this mount threads directly onto 1/2x28 TPI barrels commonly found on AR-15 pattern rifles and pistol-caliber carbines. Installation requires standard barrel nut removal and torquing procedures. Compatible with PLAN B suppressor attachment systems. Note: suppressor use is regulated by the NFA and requires appropriate tax stamp and registration.
