Yep, the AR platform with a 4X ACOG is just about ideal for nailing movers. I just have 556, because I don’t reload and ammo is $$$$. I do know DPMS makes a .243 Winchester AR, but I’ll bet the barrels don’t last long. It’s actually a 308 platform AR like an AR-10, since .243 is a necked-down .308. That would be an awesome rifle, if shortlived in the barrel.
Mine is the 4X32 and I luv it. I'd buy more acogs, but a friend told me that after 6-7 years, the illumination degrades and you have to have it recharged which today costs $400, spendy; not an easy keeper for sure. How long have you noticed until an acog's illumination getting weak? I've bought 2 leupold tacticals that were same price as acogs over this issue.
I'm going to pick up a 308 AR when I see a deal on AK List. I've also looked at a couple 338 Lapuas; Sako, Savage, and Armalite. Which one is the way to go?
