    Just noticed the dreaded 870 comp crack (1/4")on the rear of my ejection port. Have seen them welded (not pretty, but functional). Is there another way to remedy the problem??

    Have a slot similar to the one in an 1100 receiver milled thru the existing crack, then use a larger end mill to make a relief at the end of the slot.

    A small hole drilled at the very end of the crack might help the thing from getting longer until you can get it fixed correctly. The hole you drill can be filled with J B Weld and might not look too bad.

    Do what Pat said before you shoot it again or the crack will become too bad to fix.

    Mike- Fixing it correctly can mean many different things. If you drill the hole, fill in with JB Weld (the stuff is black) and are happy with the gun, than that might be a correct fix. For others, drilling the hole, welding the crack, polishing the weld and bluing the receiver might be the correct fix for them. Others will believe the only correct fix is to sent the receiver back to Remington and ask for a replacement.

    For you, the correct fix is anything that stops the crack from getting bigger and makes you happy.

    A month ago, I sent a cracked 870 comp receiver to Remington. I received it back with a note stating "Obsolete; repair parts not available."

    I have never checked but other than the stamped name I doubt that there is any difference between a comp frame and a standart frame. You may be able to replace the receiver with an old stock 870 receiver.

    Don't they normally want a slot cut back to where you drilled the hole?

    Not sure, some say yes, some say it doesn't matter? Still hoping some concrete info will come through. As of now, will just leave the hole as shown and watch the area.
