The Adams Arms gas piston conversion kit is a complete retrofitting kit that takes a standard direct gas impingement system AR-15 and converts it with 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 he firearm operational. This kit can be added to your rifle with no permanent modifications; however some free floating handguard will not be compatible with this system. The manufacturer has a complete list of compatible hand guards.

"Great piston. It works without a hickup. I wished they had an adjustable nut for the spring so you could use any rails whenever possible due to the height. The barrel nut width should not be an stopper to be able to install this.Other than that super reliable with factory handguard and approved rails."
