Re: KAC SR15 LPR.....accuracy expectations?
I'm coming close to the conclusion that if you are not rocking a bull barrel on your AR, then you better get the whole "shoots .5moa all day long" mind set out of your mind. Bull barrel = max accuracy = great for target/varmint = handles barrel heat and vibration = bench rifle... bull barrel AR's will give you max accuracy, but it will be nothing you will be able to really grab and go with over long distances. Each rifle has it own purpose.
As for my LMT, your 18" PredatOBR on the way, and your new KAC SR15... rifles with heavy barrels or light barrels are NOT .5moa all day long rifles. I would be happy with any groups under 1-1/2" and especially under 1".... if you can get 6groups, 5shots each, all in a row, AND <span style="text-decoration: underline"><span style="font-weight: bold">all under sub moa</span></span>, then you got yourself a kick ass rifle WHILE proving to yourself superior shooting skill.... driving a gas gun is just as important to the quality of the rifle.
Not saying your KAC or your 18" PredatOBR on the way will not be a .5moa all day long type of rifle, but it is DAMN HARD and the shooter plays a more important role than the rifle itself IMO. 40%shooter, 40%rifle, and 20%ammo. A more realistic expectation would be, "will my rifle be a sub moa shooter?".
