I've only taken out my Ar with a Cna barrel and bcg once so I cant say they've been tested much but ive got spare funds so s it worth getting a better Bcg and or barrel?
Who makes cna stuff? I've never heard of them. Depending on how hard you run your gun I would recommend a stag, bcm, dd, cc, colt, lmt off the top of my head for a bcg. If you are a once a month guy with 100 round per trip guy what you have should be fine.
