Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

Minimal Profile to Fit Under Handguard Or With Integral Accessory Rail

Aluminum or steel gas blocks give the choices you need to create a custom-built rifle with a mission-specific configuration. Mounts securely to barrel with included setscrews. Clamp-on models squeeze around the barrel as you tighten the side-mounted setscrews. Slip-on models are anchored by setscrews on the underside. Low Profile fits under a free-float handguard and lets you use a longer on carbine-length barrels for a clean, streamlined look with more gripping surface. Extended Nose is like Low-Profile, but with an extended sleeve that covers taper pin holes left by the issue A2-style sight tower. Varmint fits heavy .936" O.D. barrels. Bull Barrel includes a 3-slot, low or high Picatinny rail for mounting accessories.
