I took mine out last weekend. I didn't get through a whole mag before I started having issues. The rail was not loctited in place. My scope started walking off paper when I realized what had happened. Also pmags work like shit in it. I ordered a couple steel mags to shoot with hopefully they won't have such horrendous feeding issues as I had with the pmags. Some of the issues I had were in ability to pull bolt all the way open while extracting an empty casing as well has poor feeding. If it doesn't get better with steel mags I'm going to sell it and find another toy to play with.
On the positive side the trigger is crisp. Every pull was a surprise when it fired. Fit and finish are nice. Over all its a sweet rifle, I just need it to work well with a mag and I'm golden.
eta: if you do buy one make sure you tighten down your rear iron sight. Took me 20 minutes to find it after falling off.
