well it was only to get it sighted in on paper. shot it 10 times. the only issue I had if I had to pick something is the bolt. 1st it seems to be in the way when I have my hand on the trigger and 2nd it would hang up when putting a round it the chamber. Although I think it could be me not pushing evenly forward on the bolt. I never had a misfires or splitting shell cases. If the bolt only had a little up sweep at the end it would be out of the way of my hand. So far I'm pretty happy with the gun. All my shots grouped together, but I was only 5 yards from my target. I also looked up pillar bedding and bedding a stock. Midway USA has a how to on youtube. He made look way to easy and they did it to a wood stock. Don't know if synthetic is done the same way. One thing I saw that I believe a lot of unhappy bmag owners will benefit from would be the pillar bedding. That will be my first alteration to the stock, but I think I better use a gunsmith. If I mess up the mounting points I'm screwed. I'll bet accuracy is greatly improved with this mod. Good luck.
