Been looking at the 7.62x39 in an AR platform for a semi-auto deer carbine. There are a lot of really interesting AR variant cartridges out there I started looking and but when I saw the prices for barrels, uppers, mags, ect. .
So, I thought maybe the good old AK round that I already have a good supply of brass, bullets in both .308 and .311 and dies. Not to mention milsurp for plinking may be the way to go. My questions to any owners of this caliber in an AR is how much diffrence will barrel length play? I can find uppers in 16" but 20" may be a bit harder to come by. At any rate I would be interested in opinions or commentary on the best way to go for a Bambi blaster.
