The Rugged Suppressors pistol suppressor piston in M14.5×1 LH thread (Rugged part no. OP008) is the piece that ties a booster-style pistol suppressor mount to the barrel of your handgun. It is cut without slots, so it seals gas around its full circumference, and that seal is what cuts the blowback you feel behind a suppressed pistol. Rugged machines it from 17-4 stainless steel and heat treats it after machining. This listing is the M14.5×1 LH version, one of nine thread pitches Rugged offers on the same piston, so match it to your barrel or muzzle device before you order. On a fixed-barrel host such as a carbine or subgun, the spring gives way to a Fixed Barrel Spacer.

Key Specifications

• The thread is M14.5×1 LH, a left-hand metric thread that has to match your barrel or muzzle device exactly.
• The piston is machined from 17-4 stainless steel, a corrosion-resistant alloy suited to a part that sits in the gas path.
• It is heat treated after machining, which Rugged says makes the piston built to last.
• The design is non-slotted, so the piston has no gaps for gas to bypass.
• That non-slotted shape creates a full-circumference gas seal at the piston.
• The seal drastically lowers gas blowback, which makes shooting behind a suppressor more pleasant.
• On handguns it is generally used with a booster system, where the piston works alongside the spring and retainer.
• On a carbine or subgun with a fixed barrel, the spring is replaced with a Fixed Barrel Spacer.
• Rugged offers this piston in nine thread pitches, so this M14.5×1 LH listing is one specific fit among several.
