Adams Arms AR-15 Gas Piston Conversion System

  • 46777

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)

  • Bushing Installation Rod
  • Bolt Spring
  • Drive Rod with Bushing and Spring

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 is intended for barrels with carbine-length gas systems and a .750" diameter gas block seat.

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.
