remington 870 Marine Magnum problems. Please help!
I just picked up my Remington 870 Marine Magnum and I am trying to break it down for an inspection and cleaning before I take it out for shooting. I take the barrel clamp and the extended magazine off leaving me with the magazine cap. This is where I'm having problems. I'm watching disassemble videos and these people are twisting them off with ease while I'm resorting to a towel and this weird spring snap wrench that has a very tight grip to no avail. I just don't know what to do. :confused:
Note: It was said to be brand new with the exception of 30 rounds through it by the seller. There is still crap in the ejection port from when the seller shot it so I'm assuming he never took it apart to clean anyways.
