Rugged Suppressors Piston M14.5×1 LH — 17-4 SS

The Rugged Suppressors Piston M14.5×1 LH is a non-slotted piston engineered to create a full-circumference gas seal. This design reduces gas blowback for a more controlled and comfortable shooting cycle. The piston is machined from heat-treated 17-4 Stainless Steel and finished in Copper for durability and corrosion resistance. When installing on fixed-barrel platforms such as carbines or subguns, the spring must be replaced with a fixed-barrel spacer; note that the M16x1 LH piston is not compatible with Kriss Vector firearm hosts.
