Just got my USC/UMP conversion back from Ed at HDPS. It looks fantastic by the way!
Just had a question about the assembly process. For some reason I can't get the extractor to stay in it's groove. I'm pretty sure I'm putting it in right but then when the bolt is pulled back, the extractor just falls out. Also the mags don't wont seat all the way into the receiver. It looks like the barrel's feed ramp is protruding into the mag well...as if the barrel isn't far enough into the receiver but I'm not sure how I could get it to go in farther due to the roll pin holding it in place.
Any info on why I'm being a moron would be great...I obviously don't know completely what I'm doing.
