    Just received this upper after waiting just a little over two weeks from ordering. Finish is as described and fit to Spikes Tactical lower is just as it should be. Finish between reciever and rail is seamless. One thing that could be added is some sort of marking of the caliber the upper is chambered in. With a lot of searching on the barrel under the rail with a flashlight I see faint markings of BLK but nothing obvious. It would be nice from a consumer standpoint if either exposed part of barrel or receiver were stamped with caliber. Other than that, I can hardly wait to run some lead through it!
