Adams Arms PZ Pistol 11.5-inch 30Rds 5.56 BLK Features:

The Adams Arms PZ is built around a short stroke piston system which ensures that the gas which is siphoned off to cycle the action does not get returned into the chamber like with DI systems. Instead the gas is used to operate a piston rod which cycles the action reliably and with great regularity. The PZ is a great off the shelf model that provides you with an incredible value for your piston gun spend.
