Have an AR that I had a smith do the barrel/upper work for me some years ago and I assembled the rest. Has a BCM 16 inch pencil battery with mid length has system. BCM upper and BCM bolt/carrier set.
Anyway, it has never shot any better than 5 MOA using mostly privy partisan m193 and a number of other random boxes of .223 and 5.56 trying to find something it likes. I have AK74s that I have built that shoot surplus 7n6 better than this rifle.
Everyone online seems to think that it should be capable of shooting at least 2 MOA or better and that there is something wrong with how the barrel and upper were assembled.
I don't have time to mess with it myself but would like to know who I should take it to to have it looked over and rebarrelled.
