I am a huge 870 fan and have a love specifically for the marine magnum. I’ve got one that’s 2008 manufacture one that’s 2013. I got my brother one in 2018 which was ordered directly from the factory all have been tested. The oldest one is what I use as a patrol shotgun which I shoot very regularly never had a hiccup. My brother shoots clay pigeons with his at the house with good success. They’ve always been reliable and make for an extremely well wearing gun the one that goes with me everyday has just a couple ever so slight shiny spots from carrying it. If it were me I would buy another tomorrow if one is worried about quality keep in mind for every “problem” that’s boasted on the internet how many hundreds if not thousands are running strong.
