I recently purchased a Remington 870 tactical with the 6 shot fixed tube and finally took it out shooting a few weeks ago and I started having problems. Almost every other shell would get stuck in the mag tube, I noticed that the left shell stop would not disengage properly and I was chucking the piss out of it and it still wouldn't come out. I have to stick my favorite booger hook in there and push the shell stop over a bit and rack it again. Sometimes this help sometimes it doesn't. I'm completely new to shotgun owner ship and I'm not quite sure what I should do... for what its worth my mag spring is pretty damn weak unloaded so maybe that's an issue? Any help is muy apreciado.
