The KAK PLAN B A7 FH is a precision muzzle device engineered for shooters who demand repeatable lockup and a solid seal when pairing their rifle with a suppressor. Built on a tapered-then-threaded design, this 5/8x24 adapter (.375" bore) creates the kind of consistent fit that matters when you're running suppressed—no guesswork, no rocking, just reliable performance shot after shot. Kak Industry designed the Plan B line specifically to work with Plan B suppressor hubs, giving you a matched system that performs as intended.
Made from 17-4 stainless steel with a nitride finish, the Plan B A7 FH weighs just 2.2 ounces and measures 1.850" overall length—light enough not to throw off your balance, robust enough for hard use in the field or at the range. The milled rear flats give you solid purchase during installation, and the engraved thread pitch stays legible long after the wrench comes out. Best of all: timing is not necessary. Screw it on, torque it down to 20–25 ft-lbs (Rocksett recommended for assembly), and move on to shooting.
If you're building a suppressed rifle or upgrading your current can setup, compatibility matters—some suppressor manufacturers won't cover warranty claims if you mix brands. Running a Plan B device with a Plan B hub eliminates that headache. It's the kind of detail-oriented engineering that separates a solid suppressor mount from one that'll leave you second-guessing yourself in the field.
