I work on RRA rifles on an almost a daily basis at work (as we sell a lot of them). Most of the work is customizing and not functioning repair.
My two biggest complaints about RRA ARs is that their gas keys are staked like sh** (already mentioned here) and that they use about a 1/2 bottle of blue Loc-Tite between their carbine receiver extensions and lower receivers.
Proper assembly doesn't require Loc-Tite to secure a receiver extension. Torque and staking works just fine as directed in the US Military Techincal Manual, few companies properly assemble ARs by following these guidelines.
