Mine had to be sent back twice. Once to North Silva/CSA before they went to movie arms for warranty. Second time to movie arms. First time broken bolt and the second time damaged bolt and cracked carrier. After that and since the warrantie is 5 years I have pledged to put it through the ringer. I would say at least 600 rounds or so later and no issue. I finally love this gun again and will pump rounds through it unil it breaks again. At this point I think Movie Arms made it right.
I will be on the 958 train as these things are just too much fun. As for accuracy in 762x39 between 25 and 75 yards I am not missing. It is not necessarly a tack driver but for me it is plenty accurate for a close range gun. Swiss cheese cans all day!
