has anyone tried the APOC armory uppers? I noticed MrGunsnGear had a good experience with their TITAN upper, and they're priced right around Aero precision (maybe a bit more) for a fully CHF nitrided upper. Was looking at them but didn't know what their track record was in the community (specs are great, but we all know that specs and quality of assembly/customer service are two different things)

I haven't tried any of their uppers, but I have purchased other parts from them.  Quality has been excellent.  Good service so far.  Free shipping is nice.  No complaints, in fact I'm ordering some more parts from them as we speak.

I bought several nitride BCG from them, gtg, on par with my DSG BCG.
