Boxing up my RFB to go back to Kel Tec for the second time, same problem. Note: Shooting without a suppressor. With the original gas piston & the gas adjuster screwed all the way out (or removed), Winchester Super-X 150 grain slams the bolt into the top cover weldment & bends it. (& locks back). Their technical support said to order the suppressed gas piston & it would work. Nope, with the adjuster screwed all the way down the bolt won't go back far enough to pick up the next round let alone lock. You could say I'm not too happy with a rifle that can't shoot factory ammo without self-destruction.
