I got a Mossberg Maverick that doesn't have a rusting problem. Remington must really be going downhill. Well Remington has been going all downhill since they introduced the 597 that could not feed a full mag without jamming.
The 597 I had functioned 100%. It would feed every kind of ammo I fed it, From sub-sonics to hyper velocity. The generation 1 and 2 mags had a lot of problems. I switched to the 3rd generation and problem solved.
