Adams Arms P Series Piston Kit with Adjustable Micro Block – Carbine Length with Standard Carrier

The Adams Arms Piston Kit converts your Direct Impingement AR into a Piston-Driven system.  This kit uses the existing gas port on the barrel to work the action of the included inverted piston.  Firstly, instead of directing the gases into the receiver, they go into a gas plug and drive rod sleeve.  Secondly, the contained gases within the drive rod sleeve push the bolt carrier rearward using the pressure to cycle the action.  Also, the P Series Piston operating system mechanically actuates the bolt carrier external of the receiver.  Therefore, this keeps the internal receiver and all its moving parts clean and free from heat and carbon buildup.
