Also, I was at a buddy's house today and decided to bring my lower with. I was looking at his old top load AR and tried to put his upper on my lower. His upper attaches to his lower with now work at all to insert the take down pins. However, it was super tight when trying to put it on mine and I decided to not go any further than what it did. Anyone have similar issue? In assuming it may be a good thing to have all the pieces very tight together, but am not sure. Sorry for my ignorance guys and thanks for the help.

I skipped the dpms and cmmg version triggers on the stock out of the box rra is better they tend to come standard no upcharge for chromed bcg, makes cleaning a snap. Rra just had better fir and finish. Looks and feels like a more professionaly produced machine

Tight is good. Just the standard upper lowers from rra that havent been mated together have better fit than higher end uppers and lowers. My rra lower is just a non special lower and you cant see any light between it and the nm upper. There is no wiggle at all.

While a looser upper lower fit doesnt mean much it CAN in extreme cases cause the bcg to bind slightly in the buffer tube and be a frustrating cause of intermittant fail to feed/eject.

I agree, rra seems to be an excellent company. Now you have the RRA lpk? Or is it an upgraded trigger? I have a standard bushmaster lpk and my trigger pull is like 8lb's.

As far as the lower being tight, that makes me feel a little better. I almost couldn't get the pin out, and it wasn't all the way in. I mean, I don't mind if no harm is done and maybe it won't be as tight on the RRA upper.

yes its got the rra nm 2 stage chrome innards. its probably the best trigger group short of a gisele or timiny. the rest are also rra.

Oh nice. How do u like the 2 stage? I've never used one. Im definitely going to upgrade the trigger too. Not sure if I'd like a 2 stage tho
