Replaces the factory front sight/gas block and allows you to tune the gas system for smoother cycling and operation. Especially critical on match and varmint rifles when shooting both factory and custom-loaded ammunition, suppressed rifles or with rifles with oversized gas port holes.
A simple set screw lets you control the gas flow, so you can customize the setting for each load or fix an unreliable rifle with feed and timing issues. An additional 6-32 set screw can permanently set your gas adjustment screw to keep it from creeping out over time. Three hex head 8-32 set screws clamp the block securely to the barrel. Installation instructions included. Features a picatinny rail on each side for mounting flip-up front sights and other accessories. CNC machined from billet 7075 aluminum and hard anodized. Fits barrels with .750" O.D. at gas block. Includes set screws.
SPECS: 7075 aluminum, hard anodized, matte black, quad picatinny rail
