This gun is overall decent, but could just quite a few internal upgrades. The MK12 SPR performs decently, it had a good range with an matching accuracy. it also comes with a awesome bi-pod..
_comes with bi-pod,fore-grip,and 2 rail covers..
_Very nice flip up sights
_Terribly lose mag fit that's really annoying
_Battery rattles around
_Grip is uncomfortable for lefty's
_Mag that comes with gun isn't too good
