I bought one three years ago. It will shoot under an inch with any ammo. I did have to put riser on the flat top to get the scope up high enough for me to see through. I put a 3.5 - 10 leopold on it. My only complaint is that it is a little to heavy for long hikes. I use mine for calling coyotes. That 20 round mag is sure handy when 3 or more coyotes decide to show up at the same time. Mine did have just a little bit of play between the upper and lower but I used a rubber bushing to improve that.
