I had heard that they were heavy, but DAMN!  I can't decide whether I should build something with it or just use it to pound in fence posts.  It's also VERY tight on my lower and will need a little work to fit right.  I originally intended to build a .458 SOCOM with it, but Red Jacket bought up all the barrels.  

Has anyone used one of their uppers?

I have used both the Hi-Pro and Lo-Pro uppers with no fit problems whatsover.  Are you upset by the fact that the extruded, thick-walled DPMS slick-sider uppers are 2 oz heavier than a GI forged flattop?  IMHO not an issue.  Here are some I have built.  No issues whatsoever.

Love the slick sides, myself. I really wish that I could find one to fit my RR 308 lower.

That makes them 4 ounces heavier than a forged upper without the forward assist.

I'm not upset, just surprised how much thicker and heavier it is.  I really like your side-charging setup.  Did you do that yourself or have someone else do it?  Is that a plug where the traditional charging handle goes?

Yes, did it myself on my drill press.  Drilled a series of closely spaced holes, then milled the final slot with a 5/16 end mill.  Chucked the upper in my slide vise to finish the cut.  I cut and shaped a plug for the charging handle out of a chunk of aluminum.  It's held in place with a small countersunk screw installed from above.
