The Dead Air DA402 P-Series Piston is a replacement or additional piston assembly engineered for shooters running Dead Air's Ghost-M suppressor platform. This piston features M13.5x1 left-hand thread pitch, matching the specifications needed for compatible Ghost-M host barrels. Whether you're building a second upper, swapping calibers, or keeping a spare on hand, having extra pistons means you can adapt your suppressor setup without waiting for parts or compromising your shooting schedule.
Dead Air pistons are precision-manufactured components that directly affect how your suppressor interfaces with your barrel. The M13.5x1 LH threading is specific to certain barrel profiles and host systems, so compatibility matters—this piston is built to the exact spec needed for Ghost-M integration. Black finish matches Dead Air's standard aesthetic and resists corrosion through repeated use and cleaning.
Suppressors that use quick-attach or quick-detach piston systems offer real modularity: you can run the same suppressor on multiple uppers by matching piston threads to each barrel. That flexibility is why serious shooters keep backup pistons in their gear bag—no surprises at the range or in the field, and no reason to leave a suppressor at home because the piston doesn't fit today's rifle.
| Product | DA402 P-Series Piston |
| Brand | Dead Air Armament |
| Thread Pattern | M13.5x1 LH (Left-Hand) |
| Color | Black |
| Compatibility | Ghost-M Suppressor |
No—this piston is designed specifically for barrels with M13.5x1 left-hand threading that are compatible with the Dead Air Ghost-M suppressor platform. Check your barrel's thread specification before ordering to ensure compatibility.
A piston is the interface component that threads onto your rifle barrel and allows the suppressor body to attach and detach. Having multiple pistons lets you run the same suppressor on different barrels without needing a full suppressor for each rifle.
Suppressors typically ship with at least one piston, but this is a standalone replacement or additional piston for users who want extras or need to match additional barrels to their Ghost-M.
