I zeroed mine with good old American eagle 55 grain and it was an easy and all day 3 MOA with my Holosun red dot. That is basically regular old AR performance with that ammo and a non-magnified red dot. I would guess the trigger is the real weak spot. It isn't FS2000 bad, but it is definitely FN SCAR/ 80s bad. I think if you aren't used to working with less than stellar triggers you could have trouble wringing decent accuracy out of the gun. That's a shame because the AR70 had a really good trigger and there is no excuse for a commercial gun in this day and age not having a good trigger. Still I have only had one and I am usually pretty lucky but I don't see any evidence of mechanical accuracy issues. I would LOVE one in 7.62x39...it certainly interests me more than the Bren2 or other non AK 7.62x39 options.

This weekend I may do some informal testing. I have a 3x magnifier and will bag it up good and shoot 55gr, 62 grain and good Lord a few precious 77 grain just to see.
