Sure the scope is useful for decreasing spread and all, but at close range its useless and at middle range the slow walking speed while scoped in will probably get you killed (unless you quickscope). I had the R870 MCS MOD for 7 days and I didn't really like it. IMO the M590 CQB Mariners is a much better shotgun. Low spread and high damage makes it a 2 shot kill even up to its maximum range and it will occasionally 1 shot in close range. I managed to get a perm one with a renewal kit.
