Great idea, but poorly executed.
I bought this on the 308 sale (on 3-08). I also ordered the 17 Design upper receiver knowing that there is no "mil-spec" for AR-10's. My thought was getting both components from the same manufacturer would guarantee that they match. Not so! The upper and lower are completely different colors. On Brownell’s website under finish, it just says "matte." Sooo, the "deal" is not so good because I will have to Cerakote the receivers so they do match. Second (and worse) I tried to show in the attached picture that the machining doesn't match up. The metal is higher or lower in different spots and there are various gaps where the light passes through... I decided to give the lower 4 stars because it is a great concept. I am giving the upper 3 stars. I don't know which is out of alignment (maybe both), but I'm hoping it will function well. Otherwise, I will change my review.
