Remington 870 binding with the new forearm

[gjohnsoniv]

I have a Remington 870 Police Magnum from 1970 and have replaced the wood furniture with the Blackhawk Knoxx stock and forearm. The problem though is that it seems like the new forearm doesn't want to go on correctly, and seems to make the pump bind when you go pump it. Is this because of a change in design of the forearm tube and arms, or just needing to file out some of the inside of the new forearm.

There are some little brackets that go across the forearm that need to be taken out. As the forearm comes back the little brace starts binding on the portion of the barrel where it starts to flair out at the reciever. I spent hours with the same problem thinking the littles braces were necessary. Poped them out and it was good to go. I'll try to get some pictures tomorow to show the braces.

Okay great. I'm not really sure which pieces to which you're referring so a picture would be greatly appreciated. I spent quite a while trying to figure it out but nothing worked so I just ended up putting the wood forearm back on for the time being.
