I have a Scar17, M1a, ptr91, Armalite ar10. I choose the scar. I might be tempted by a Larue and I also like the looks of the Ruger SFAR.

My first 308 semi-auto was a Stoner SR-25 Match, I kept it for about 15 or so years, most of the time it sat in the safe, not that it was a safe queen, it was just boring to shoot our range only goes out to 300yards. To shoot further I had to either go to a friend’s farm or drive 1.5 hours to Salina’s 1,000yd range.
Sold it, it just didn’t make sense for me. After that I had a myriad of 308 semi-autos starting with it was still early in the 308 AR game and the selection was pretty thin. I picked up a DPMS LR-308, to scratch the occasional itch. 24” stainless fluted barrel, JP Enterprise trigger, adjustable gas block, bla, bla, bla, tried building a load for it but nothing came close to the SR-25. After several other 308 semi’s including a genuine HK91, Belgian FN FAL, a plain Jane M1A but I didn’t like the fit.
Finally SiG introduced their 1st gen 716, I picked one up and it did speak to me, its heavy and still not an SR-25 but it was 1/3 the price and accuracy is almost as good as the ST-25. It also spends its time in the safe and it’s probably been 5 years since I’ve shot it as my shoulders are “shot” … but I might be able to shoot it, it’s heavy and I can can put my suppressor on it, so maybe the recoil wouldn’t be too bad.
I’ve had a SCAR16 which I didn’t like but haven’t owned the 17. As expensive as they are I don’t expect I’d like it … that may be a self fulfilling prophecy but at my age I’m probably done buying firearms.
