Wasn't Rock River adopted by the DEA? I would think that elevates them above paper punching and toy status. The only reason pertinant is there are testing procedure in place before any weapon system is adopted by a govenment agency. Unless the guns delivered under Gov. contract had different internals than the civvy version. Other than Colt M4s, and a few Colt ARs that I had shot myself, when I got the funds to buy an AR I had to consider all that had been said and decide who to go with. I went RRA, and have no complaints. I've personally never heard a legitimate beef against them, and they come with an accuracy guarentee, fwiw.
