Was wondering if anybody knows who has a good reliable .45 or 9mm upper that I can put on my RRA lower.
I've looked at the .45 upper from Olympic Arms and the 9mm unit from RRA.Are there anymore choices out there?
On the RRA 9mm upper other than the insertion block for the mag well is there anything else that I need to do to the lower?And what types of mags do they take?
I have these same questions for the .45 upper from Olympic Arms.Any help would be greatly appreciated.
