I've owned this weapon for about six months. I took it to Gunsite for the 260 shotgun class. After about 700 rnds of remington le ammo, one of the gas pistons broke in half and both "o" rings were somewhat battered.
After returning home I spoke with customer service and was asked to send the shotgun back. I explained that the piston is a "strippable" part, I send the broken one, you send me a new one with two 'O' rings. I sent it priority mail, return postage paid. This happened eight days ago. I called today and was told that the piston was being "repaired" and might be sent back
