Can anyone tell me if the POF gas piston upper uses an operating rod guide bushing? I am trying to install my POF predator rail onto my Bushmaster gas piston upper and the op rod bushing that Bushmaster uses extends out of the front of the receiver to the point that it makes contact with the POF heat sink barrel nut making it impossible to torque the barrel. Thanks for any help. |
