The Seekins Precision Advanced Tactical Compensator (ATC) for HIT is a precision-machined muzzle brake designed exclusively for the Havak HIT series platform, threaded 5/8x24 and finished in matte black melonite. Using computational fluid dynamics (CFD) analysis to optimize port configuration, the ATC spreads propellant gases across proprietary front-facing ports to deliver maximum reduction in felt recoil and muzzle rise without top ports, allowing faster follow-up shots and quicker target transitions. Includes a timing nut for effortless installation and removal without crush washers or peel washers. Seekins ATC 5/8x24 Threads (Hit Only) Black Muzzle Brake 10400080F
