Overview
The SLR Rifleworks Sentry Gas Block is an adjustable clamp-on gas block designed specifically for barrels with a .625 diameter. Its steel construction ensures durability, while the nitride finish provides enhanced corrosion resistance and longevity. This gas block allows builders to fine-tune their gas system for optimal performance, making it suitable for a variety of setups, particularly those requiring precise gas regulation in competition or tactical builds.
