The Adams Arms lightweight gas piston AR-15 conversion kit is a complete retrofitting kit that takes a standard direct gas impingement system AR-15 and converts it into a cooler, cleaner, short stroke gas piston. Installing a piston system on an AR-15 prevents the harmful gas and debris from being sent back in the chamber to cycle the firearm.
Piston systems increase overall reliability while also decreasing the amount of maintenance required to keep the firearm operational. This AR-15 gas piston conversion kit can be added to your rifle with no permanent modifications; however some free-floating handguards will not be compatible with this system. The manufacturer has a complete list of compatible handguards.

The manufacturer recommends 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.
