This rifle came up in a trade, but I'm curious if it's any good. A fellow never degrees a Marlin x7 and I'm just curious if the scout is of equal quality, worse or better. What's the moa look like at 500 yards? What's the life expectancy? Hows the ergonomics? If any one has that rifle plz help with info. I would trade a GNU FNS-40 with night sights for this pistol. Is that a decent trade?
