This system will work with .223/5.56 x 45 mm NATO.

Kit includes:
  • Patented One-Piece Bolt Carrier
  • .750"" Picatinny Gas Block with 3 settings (full gas for standard fire, half gas for suppressed, no gas for single shot)
  • Gas Plug
  • Upper Receiver Bushing
  • Bushing Installation Rod
  • Bolt Spring
  • Drive Rod with Bushing and Spring
  • Installation Instruction Card

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.

To select the correct length kit, use the following measurements:
  • Carbine: 7.866" from barrel extension to shoulder

We recommend using a standard barrel nut or barrel nut with similar measurements for proper fit and function of the kit. Many aftermarket proprietary barrel nuts do not offer the clearance for the drive rod or proper seating of the spring and bushing.
