The Superlative Arms patented Bleed Off Mode gas piston system transforms the AR-15 platform with its unique gas flow management approach. This system bleeds excess gas out the front of the block, unlike traditional adjustable blocks that restrict gas flow. This innovation enhances firearm reliability and performance while reducing recoil and wear on internal components. By efficiently managing gas pressure, it ensures smoother cycling and improved shooting accuracy.
