Which barrel do you prefer the Stainless Steel or the Chrome Moly Barrel?

And why?

Doesn't matter for close range but Chrome moly will last longer then SS. SS will be easier to be made accurate due to its soft material.

Plunking a lot? Chrome moly

Precision shooting? SS

But for 300aac? I'd go CM.

Can I use a Bolt / Bolt Carrier Group off a Pre Ban AR-15 on a .300BLK Upper?

Should an Armourer check out?

Should work. Only thing that is different on a 300aac is the barrel. Well, more like, the bore.
