Features

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.
Adjustable gas settings for various applications.
Doesn't vent directly to atmospheric pressure; this eliminates flash signature and super sonic crack which is optimal for night vision and suppresses fire.
This system requires a mid gas length (9.866" from barrel extension to shoulder) and a .750" gas seat.

Adams Arms 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.

Local Law Compliance

Certain firearm parts and accessories, including lower and upper receivers and threaded barrels, are subject to complex and frequently changing federal, state, and local laws and regulations. While a part may be lawfully sold and shipped as a component, the legality of possessing, assembling, configuring, or using it in certain states (e.g., California, Washington State, Virginia, Rhode Island) and localities depends on how it is assembled, combined with other components, and ultimately used. You are solely responsible for ensuring that any assembly, configuration, possession, or use complies with all federal, state, and local laws, including any so-called “assault weapon” bans and short-barreled rifle restrictions. We do not provide legal advice and are not responsible for unlawful configurations or uses.

WARNING: Handling firearms or firearms parts can expose you to lead and other petroleum products known to the State of California to cause cancer, birth defects, or other reproductive harm. Wash hands thoroughly after handling. For more information go to www.p65warnings.ca.gov (CA Health and Safety Code Section 25249.6).
