DEAD AIR P-SERIES PISTON 1/2X28

Suppressors rely on consistent piston operation to cycle properly and maintain durability across thousands of rounds. The Dead Air P-Series piston in 1/2x28 thread pitch handles this critical interface between your muzzle device and silencer tube. Whether you're building in Vallejo or anywhere in California, precision components matter—especially when coordinating with an FFL transfer in Sunnyvale for your complete suppressor system.

Piston Design and Mounting Interface

The P-Series piston is engineered to cycle freely within your suppressor while maintaining a tight seal around the barrel threads. The 1/2x28 pattern threads directly onto barrels common in 9mm, .45 ACP, and 5.56 platforms. This piston absorbs recoil impulses and allows gases to expand into the suppressor tube without binding.

Frequently asked questions

Does the P-Series piston work with barrels other than 1/2x28?

No. The P-Series piston is designed exclusively for 1/2x28 threaded barrels. Verify your barrel's thread pitch before ordering. Using the wrong thread pattern can cause poor fit and reliability issues.

Can I use this piston on a different Dead Air suppressor model?

The P-Series piston is built for the Ghost model. Other Dead Air suppressors use different internal geometries. Always confirm your suppressor model before purchasing replacement pistons.

What is an FFL transfer in California?

An FFL transfer is when a federally-licensed dealer like TacticCAL receives a firearm shipped from another seller and processes California's required DROS paperwork to legally transfer it to you. Find gun store Fremont at TacticCAL.
