P-Series Booster Spring

The Dead Air Armament P-Series Booster Spring is available now from LM Ironwerks, a licensed FFL/SOT dealer in Louisville, Kentucky.

The P-Series Booster Spring is installed inside of your P-Series Booster Assembly to allow cycling when paired with a P-series piston on a tilting-barrel handgun.

*Note: The SD500 Booster Assembly already ships with a booster spring installed.
