I first bought a 308 complete rifle with side charging, first time using that type. Ran over 100 rounds, cheap tula ammo, never had a failure. Was able to get 1.5 inch groups at 100yds, that's good for me. The magazine, 10 round, that I bought separate did have a problem to cycle if fully loaded. Called customer service and was shipped a new one that worked perfectly. I liked the company and product that I bought both my boys there own, 7.62x39 and 223 wylde. Have only shot the 7.62x39 and worked perfect. I would recommend Bear Creek.
