  • Modular design allows lower to be changed to different lowers. This makes the adapter interchangeable between M4, ARP, Shotgun Shell, etc. (Lowers can be found here)
  • Gas magazine included and pre-installed with single stack mod to allow faster BB flow.
  • Friction-less BB stop allows smoother feeding and prevents BB loss while reloading.
  • Recommended 90-100 PSI.
