Got one that has +3000rnds through her. Never had a single stoppage/ftf, nothing (that was not an ammo issue). I've had mine ghost ring'ed, tri rail foregrip installed on a 500 tube, couple stocks, saddle scope mount.. and the accessories cost more than the gun. I take it to the gun club on skeet//clays day and make the "old timers" cringe when I keep up with 18" of chokeless power. haha. (I do bring my proper gun, but like to stir the pot sometimes).
The Mav88 is definatly a under rated powerhouse in the shadows.
