Built to the tightest tolerances, the VLTOR low profile, clamp on gas blocks are small enough to fit inside most rail systems. These gas blocks were designed to be used when a rail system/handguard is mounted over the entire gas system. They are made from 17-4 PH stainless steel and have a matte black oxide finish. The bore diameter is 0.75" (standard barrel).
