This low-profile design sits flush under free-float handguards, eliminating the bulk of traditional front sight base gas blocks while maintaining proper gas system function for semi-automatic cycling. Upgrading to a low-profile block allows shooters to run modern handguards without interference and opens up a full-length sight radius for optics mounting.\u003c\/p\u003e\u003cp\u003eMachined from steel with a black nitride finish for corrosion resistance and heat tolerance.
