Very nice! - Luth-AR 5.56 Complete Mark 12 Barrel Kit

Bought this for my first AR build and I gotta say was very pleased with Luth-AR 5.56 Complete MARK12 Barrel Kit. Shipping was fast and packaged nicely. Comes with the MBA3 stock, which btw looks and feels right because, of the adjustments one can make with the cheek riser and shoulder rest. The picatinny rail on the stock makes mounting a sling on it easy and convenient along with the GrovTec Heavy Duty Push Button Swivel Assy.
Excellent customer service. When I first took it to the range the hammer pins were walking and a few light primer strikes so, I called Luth-AR and talked to Paul (Thanks Paul), he asked me if the hammer spring was in upside down and sure enough it was. Flipped around and now works great.
