Seekins Precision ATC Muzzle Brake 308 Win 5/8x24 Black Melonite

The Seekins Precision ATC is a muzzle brake for AR-10 rifles chambered in .308 Winchester and 7.62x51mm NATO. It is designed to reduce recoil and muzzle rise, using a port layout that spreads gas work across the device with front-facing porting intended to help the rifle track straight during rapid follow-up shots.

The brake is machined from 416R stainless steel and finished in black melonite. It threads onto a 5/8x24 tpi barrel. An included timing nut lets the brake be aligned without peel washers or crush washers, which simplifies installation and removal for cleaning.
