im not one to ask for help but this dam shotgun wont go back together. i just installed a surefire frnt grip on it and now the barrel wont go back on and its not feeding right. the whole thing thats screwing it up is this extractor thats sits against the frame of the gun. it came out when i unscrewed a screw that hold my side saddle on from the inside the action. can some one help explain in how to put it back together
thanx
