I got this together. Aside from the kit missing one spring for the safety selector which was a real pain in the ass, this is a great kit. I had to buy a lower parts kit locally. Looks beautiful. fit excellent with an ATI MilSport lower. I finally got to shoot today, and it cycled 60 rounds of Wolf ammunition without a single issue. I will upgrade the stock and pistol grip to make it all a bit more green, and I will install an upgraded trigger that is a bit smoother, but this is a CLASSIC kit. I will be buying more from Grid Defense. I wanted to leave a review because there are none and I purchased it as a bit of a calculated risk, but it was so worth it in the end.
