Re: Thoughts on these RRA Uppers?
I own 2 rra uppers. I have a flat top national match that shoots yery well. I have a nikon 2.5-10 bdc scope on it right now and shot a .7" ctc 5 shot group with it two weekends ago. Thats pretty typical performance, It would probably do a bit better if I were a better shot or if I had better optics on it. The load was 21gr varget under a 77 gr sierra mk.
I also run a 16" rra carbine upper with an aimpoint on top and have been very impressed with it also. It has been through a few carbine classes and has never given me any trouble. It also kills idpa targets out to 500 yards with boring regularity with just the aimpoint.
I have run a scope on the carbine to check accuracy and it was consistnatly sub moa, but its been a while so I dont have any hard data.
The carbine is also very heavy below the handguard making the rifle a bit of a brick, but its a shooter and very reliable.
Hope that helps
