||Good piston - 12/31/2010|
|Reviewer: ||Good piston|
|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.|
