The Dead Air P-Series Piston, M14.5×1 LH is the piston that lets a P-Series suppressor run on a threaded tilting-barrel handgun with a left-hand M14.5 barrel (Dead Air part no. DA404). Dead Air Silencers lists it for the Wolfman, Ghost 45 and Primal with the P-Series adapter. It works as part of the P-Series booster assembly and spring. This version is cut for M14.5-1LH with a .40 caliber through bore. Dead Air sells the piston in several thread pitches, so the barrel thread decides which one you need.

Key Specifications

• The thread pitch is M14.5×1 LH, a left-hand metric thread that must match your pistol barrel.
• The through bore is .40 caliber, the size Dead Air pairs with the M14.5-1LH piston.
• It is made for tilting-barrel handguns, which is where a piston and booster are used.
• It is designed to work with the P-Series booster assembly and spring, so it is part of that setup rather than a standalone mount.
• Dead Air lists it for the Wolfman, Ghost 45 and Primal with the P-Series adapter, the suppressors it works with.
