Finally got my new RRA DCM upper/lower together Friday.
This is my first civilian AR, and from what I see the quality is excellent. The fit is quite tight, but not binding. The machining is superb, wish my Ruger rifles looked like this inside of the action!
I bought the upper and lower seperately and the finish and parkerising(sp?) look as though they were made together.
Took it to the range for function testing on Sunday in 100F Chicago weather, and it was almost flawless. Shot 180 rnds. Had 3 stovepipes the first 80 rnds, nothing after that.
Hope to test it for groups this weekend.
So far I am quite impressed.
