Details:
The Adams Arms P Series Adjustable Micro Block Piston Kit converts your AR-15 into a short stroke piston-driven rifle, eliminating the downsides of direct impingement. The system is designed to vent the gases forward instead of onto the bolt; this dramatically reduces the amount of time you must spend cleaning your weapon.
The included P Series Adjustable Micro Block gives you the ability to adjust the gas level for three main types of shooting: standard, suppressed, or single shot. As the short stroke system momentarily delays the release of the gases, the noise and flash signature are reduced, making this conversion kit perfect for users of suppressors. The metal parts of this kit are given a corrosion-resistant coating.
