I just had my FNAR threaded and an AAC fast attach muzzle brake installed to be used with my 7.62SD. The brake does an amazing job in taming the recoil and muzzle rise and with the brake alone there is no shift in POI compared to before i had the barrel threaded. No adjustment of the scope was needed and 5 shots at a 100yards are touching each other when shooting with the brake alone.
Once i put the 7.62SD on it shoots 6-8" down and right at around 5 o'clock position. And again those are consistent too. I made 4 shots and all four shots were touching each other. I didnt do an exact measurement but it was at least 6" and max 8". It was enough for me to be concerned. I have a few other AAC suppressors and used to a 1-2" shift but this much?
First thought was if the barrel was threaded improperly but then again i would expect a shift with the muzzle brake itself and i dont see it. Could there be something wrong with the suppressor itself? All inputs appreciated.
