I think I got gunk on the end of the plastic piece. Probably the J-B. It worked perfectly before the cleaning.
I am not so worried about that. Like you, I think it just needs a little cleaning.
I had to scar up the Mag tube cap. It seized and the pliers made a mess of it. I got the orange plug out with great difficulty. I think it was swelled from oil saturation. I found a pin punch with a perfect size handle and stuck the follower on to that and hand sanded it down until it was again a sliding fit. I tried the ammo again, and stuffed 7 into the tube and all of them shucked out nicely.
I sent an email off to Mossberg to get a price for the boogered up cap, cap screw and follower. The tube may need to be replaced but I am betting that is a factory job.
The rifle does shoot more uniform groups now. I think after a couple million shots fired it will be wore out and I won't give a ...you know.
