9mm AR Build

[giggitygiggity]

I am looking to build a 9mm AR using the Diamond Double Law Enforcement Supply lower and a RRA upper. Is anyone experienced with how well this combination works? How does the DDLES and the RRA function together and how is the fit/finish between the two?

Should I just get the complete lower from DDLES or only the receiver. I want to ensure that the DDLES complete lower uses quality parts. Also, what kind of trigger does DDLES include in their complete lowers and how does that trigger compare to the RRA 2-stage match trigger? Thanks.

I have never used that brand lower. I built a 9mm with a Stag lower, Rock River upper, and a Hahn Precision dedicated mag block. The only problem I had (and I believe it was pretty common) was that my CProducts mags required the mag block be lowered so that the bolt could clear....RRA generally fit pretty tight, but they fit any lower receiver within spec...
