if you zero the scope at 300 yds, you can aim at the top of his head at 1/4 mile and hit him in the guts/pelvis/thighs. Not bad, for a 4 lb gun that's no bigger than an UZI. with a free float tube, trigger job, anti cant level, gi bipod (clamped onto the tube, not the barrel) and match ammo, 14" groups are quite "doable" at 1/4 mile, With a match grade Noveske barrel and upper receiver, you can hold 8" groups, silenced. The shorty AR is a truly amazing little gun. given the hpbt, it's still got over 370 ft lbs at 1/4 mile. No, Garand, it aint going to bounch off of you. In fact, it will still kill you very dead at 1/2 mile, still, assuming a good hit. Only 60 ft lbs is needed for lethality, especially with a pointed, long for caliber 223 bullet.
