"I bought one of these this summer to start shooting after ordering and waiting 6 months for my RRA AR 5.56 upper. This S&W Upper is great. I bought some surplus ammo here locally and never had one jam shooting Silver Bear 5.45x39 ammo. The ammo is almost 1/2 price what 223 ammo is going for. The best group I could get with a 3x9 scope at 100 yards was 1.5 to 1.75 inches. Might do better with a free float barrel, but maybe not..... I had also bought the Russian spam can ammo, but have not shot it yet. I was told you have to diligently clean your weapon as the primers are corrosive. Other than that, for plinking it is great."

"This is good for a gun that is good for cheap ammo. However must be cleaned after each shooting at gun range, no waiting around. Bullets dirty and will jam up gun in no time with rust and other problems."
