1. Undersized Piston
« on: October 20, 2012, 12:39:11 AM »
 Remove the operating Rod from the rifle and measure the diameter of the gas piston. Be sure to measure at least five points around it's circumference to detect any flat spots on the gas piston. If the piston is undersized there are a few gunsmiths that still replace gas pistons if needed.
