hey yall i got this remington 870 police magnum from a shop around here at a great price, fast forward a few days i got it out to clean it and in the process of taking it down the very tip end of the left shell catch broke off, dont ask how cause im not really sure, causing it to not feed or extract shells. problem is these arms are staked into the receiver and im unable to fix this, ive read its not a problem if they arent staked as the bolt will more or less hold them in place? any advice would be greatly appreciated!
