Crafted of carbon steel with a corrosion-resistant QPQ black melonite finish, the Kaw Valley Precision Linear Comp .30cal – 5/8x24 is designed to redirect muzzle gases away from the shooter for improved weapon control and reduced concussion. Multiple forward gas ports mitigate side-to-side and upward travel for enhanced accuracy, faster follow-up shots, and a softer shooting experience. Plus, aggressive grip texturing and wrench flats allow for easy installation and removal, even if partially installed under a handguard. 5/8x24 threads.
