Let me state from the outset, that I was never all that thrilled with AR's in the past. In the military, I carried a .45 Colt, a 30 Cal Carbine and an M14. After leaving the military and joining Law Enforcement, I was exposed to my first AR and several other tactical weapons. I was always a bolt gun guy, chasing ultimate accuracy and the AR's of old, didn't have the accuracy I'd become used to seeing from bolt guns. I even bought an AR back in the late 70's that I ended up giving to one of my son's once I got into Benchrest Shooting. But I did follow the remarkable improvements to subsequent AR's, although my Benchrest rifles were still my pride and joy. Then about two months ago, a local Gunsmith (and someone who I'd competed with in Benchrest Competition) showed me a target he'd recently shot on a 600 yds range using a custom built STTAR15 (San Tan Tactical Upper/Lower with JP Precisions parts/22" Supermatch 1:8 barrel and a Geissele 2 stage trigger/PRS Magpul stock. That target showed me an AR CAN and DOES produce a very respectable group, something even a Benchrest shooter would like and appreciate. So after seeing that target, seeing and feeling that AR Rifle, I had him build me one. Though not cheap in comparison with an across the counter AR, my new BABY shoots, probably better than I'm capable. So HELL YES, AR's today are worthy of being used for hunting, depending on the prey you seek. Know the limitations and be reasonable in your expectations. But give the AR the credit it deserves as there are many folks out there shooting AR's that put together some very impressive targets you can be proud of. And I'm now a BELIEVER for sure and am actually spending more time lately with my new AR than even my Benchrest rifles.
