Black D. 57 Compensator 1/2x28 .430" MAX

OVERVIEW:

Design 57 was created to be our first dedicated compensator, with five .125" holes over five slots, with the bottom slot left filled to prevent dust up while shooting prone. It also features a caliber specific .29" through hole, with a .468" expansion chamber inside the device. The main body also tapers down to .75" to assist in weight reduction.

All devices come standard with a free steel crush washer, but other locking options can be purchased to fit the build you're after.
