I'll post some pics of the build in it's entirety, but snapped some pics of the upper receiver awhile back.
I found a heck of a deal on a LesBaer upper receiver. It's pretty nice. I ended up having to file the sides of the lugs so it would fit into my lower. I basically just took the finish off, and did try it on other lowers first. It's a tight fit to say the least...
Overall I'm very happy. It didn't have quite as dark of a black color as my lower the frish rail that's on it now, but it looks ok. I like the lack of forward assist on it... Makes it look "clean"...
