ADAMS ARMS Adj. Micro Block LM Piston Kit MID

Adjustable P Series Micro Piston Low Mass Conversion Kit for Mid Lenght DI Gas Systems

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

GEN2, Upper Receiver Bushing and Installation Dowel is no longer needed!

AA Gen2 Conversion Kit includes:

• Patented One-Piece Low Mass Bolt Carrier, DLC coated
• P Series Micro Block – Adjustable with 5 Settings – 100%/74%/53%/32%/11%
• Bolt Spring
• Drive Rod with Rod Bushing and Rod Spring
• Gas Block Shim Spacer

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

Doesn’t vent directly to atmospheric pressure; this eliminates flash signature and super sonic crack which is optimal for night vision and suppresses fir

To select the correct length kit, use the following measurements:

• Pistol: 4.846″ from barrel extension to shoulder
• Carbine: 7.866″ from barrel extension to shoulder
• Mid: 9.866″ from barrel extension to shoulder
• Rifle: 13.241″ from barrel extension to shoulder
• For .300 BLK we only recommend a Pistol Gas Length and a Low Mass Carrier for optimal performance

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
