Yankee Hill Machine Slant AR-10/308 300 BLK Comp Muzzle Brake

The YHM Slant muzzle brake for AR-10/.308/300 Blackout features angled ports that redirect propellant gases upward and to the side at a slanted angle, providing effective muzzle rise compensation and recoil reduction for larger caliber AR-platform rifles. The slanted port geometry produces a controlled, directional gas venting pattern that delivers a smoother recoil impulse and flatter muzzle tracking between shots — particularly valuable in .308 Winchester and similar cartridges where recoil is more substantial than in .223/5.56. The compensating function keeps the rifle on target during rapid fire, reducing the time required to reacquire the sight picture and improving follow-up shot speed for precision and practical shooting applications. Thread pitch is 5/8-24, the standard for .308/7.62 and 300 Blackout barrels. Install with a crush washer or peel washer for proper timing and torque to manufacturer specifications using a barrel vise and armorers wrench. Verify your barrel thread pitch before ordering. Made in the USA from steel with a durable matte black finish for corrosion resistance and heat tolerance.
