Low-profile steel gas block designed for .936 diameter bull barrels. Replaces A2 front sight, enabling longer rail installation. Includes roll pin and set screws. Compatible with 5.56/.223 and .308 platforms.
This all-steel gas block represents a practical solution for AR-15 builders seeking a compact, low-profile design that maximizes rail real estate.
This gas block excels when you're building a short-barrel rifle but want to run a longer handguard. It's particularly useful for builders who need to match a shorter gas system to a bull barrel while maintaining a modern, streamlined profile.
Simply replace your existing A2 front sight assembly. The included hardware ensures a secure, repeatable installation without requiring any barrel work.
