I bought one from a local gunshop here. Was shooting it from a bench and was VERY accurate , but the gun was not functioning right. Can't recall what it was doing , but the groups were so tight I was hoping it would smooth out with a few more shots. Fired one round and the gun opened way too early. Never did figure how it could do that. Anyway a jet of gas / burning powder shot up out of the reciever , hit the brim of my cap , and deflected into my face. Hurt like ****. My shooting glasses saved my eyes but gas went over the top and into them . When I took them off , I looked like a raccoon . I went straight into the gunshop , threw the rifle on the counter , and demanded a cash refund. One look at the powder marks and he did so and also pulled the ones on his rack and started calling everyone who had bought one. Sent them all back.
More the pity because I was getting close to MOA groups out of Hanson mil-spec ball.
