The Adams Arms Piston System:
- A short stroke free floating piston system.
- Is Self-Cleaning.
- Carbon and gases are expelled forward, away from operator.
- Corrosive resistant coating processes.
- Harmonics are not transferred into the barrel.
- Adjustable gas settings for various applications.
- Doesn't vent directly to atmospheric pressure; this eliminates flash signature and super sonic crack which is optimal for night vision and suppresses fire.
This system requires a pistol gas length barrel (4.846" from barrel extension to shoulder) and a .750" gas seat.
