Questions & Answers
Will this work for a 300 black-out build with any standard Bolt and Charging Handle? Expert Answer

The manufacturer states: The Adams Arms Left-Handed P Series Adjustable Micro Block Piston Kit will work with .223/5.56 x 45 mm NATO. For other calibers, please contact Support. It should work fine with 300 Blackout but I would still recommend reaching out to Adams Arms directly for confirmation.

Product Info for Adams Arms Left-Handed P Series Adjustable Micro Block Piston Kit

The Adams Arms Retro-Fit Piston Drive System uses the same gas port on the barrel to work the action of our inverted piston. Instead of directing the gases into the receiver, they go into a gas plug and drive rod sleeve invented by Adams Arms. The gases are contained inside the drive rod sleeve and push the bolt carrier rearward using the gas pressure to cycle the action.image

Adams Arms proprietary operating systems mechanically actuate the bolt carrier external of the receiver. This keeps the internal receiver and all the critical moving parts clean and free from heat and carbon build up.

Here are some of the main differences when using the Adams Arms Operating System:

Short Stroke Free Floating Piston System

Self Cleaning

Carbon and gases are expelled forward, away from the operator

Bolt Carrier Group and other critical components remain cool and clean

Corrosive resistant coating processes

Harmonics are not transferred into the barrel

Adjustable gas settings for various applications

Doesn't vent direct to atmospheric pressure; this eliminates flash signature and supersonic crack which is optimal for night vision and suppressed fire

Features/Specifications:

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

We recommend using a standard barrel nut or barrel nut with similar measurements for proper fit and function of the kit.
