870 feeding problem

[Grifter206]

Just bought a brand new remington 870. I just installed the black specops stock and forend....... suddenly the damn carrier will not go up. Please help????? Any suggestions?? thanks in advance!

Uninstall the specops stock and forend and do a function test to determine what is getting in the way and how.

Then either install it again so it works, modify it to work, or determine that it won't work and get another forend.

Good universal advice.
