AR's are lighter, more compact, more accurate, less recoil and can be configured any way you want with different stock and handguard options. My vote is the AR all day every day.
There is a reason so many countries use ak47 = reliability & toughness Ak goes bang every time ak all day
I'd go Ak the 7.62x39 has more energy and is more reliable. The difference in accuracy under 150 yards is not going to make a difference. Those that say a 300BL is the same as a 7.62x39 must think a 308 win is the same as a 300 win mag. The energy % difference is the same.
Forget the bear spray, use wasp killer. Concentrated delivery stream, 10X the product, and only $3.00 on sale.
I just noticed that Ruger now offers a 300 Blackout in their mini-series rifles. That would be sweet, especially with a suppressor.
