Description

Details

This system will work with .223/5.56 x 45 mm NATO in Rifle Length ONLY (see Gas Length Diagram). 13.241" from barrel extension to shoulder.

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
  • Rifle Length Drive Rod with Bushing and Spring
  • Installation Instruction Card
  • FREE Samson Evolution 12" Extended Rail

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.

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.
