Very nice upper - Black Rain Ordnance AR-15 Milled Upper Receiver

I bought this upper to compliment a Black Rain Milled Lower I have. I tried a different upper on the Black Rain lower and there was a lot of play between the parts. This upper fit the Black Rain lower very Snug. It was so tight that at first I had to tap it with a rubber mallet to get it to release from the lower. After a couple trips to range and a few hundred rounds it open just fine and when lock up with the pins there is no wobble between the upper and Lower. I was amazed at how light this upper appeared. The machining and finish was perfect. I amounted a 20", Whylie Chambered barrel to this upper, with a Free Float Slotted Fore grip. the Accuracy of this Rifle was all I had hope it would be. The Only issue I encountered was Not with the Upper but the Lower, I guess its the thickness but a Magpul Bad lever will not work with the Black Rain Lower. I was not real thrilled with the Bolt carrier I had so I had so I just ordered a Black Rain Bolt carrier group.
