I’m putting together a 16” .308 AR and had planned on a Criterion barrel but their 16” barrels with mid length gas system are out of stock. I searched Google and didn’t find any other distributors with any in stock. Criterion has rifle length gas system barrels available but from what I’ve read I would be better of with mid length.

Any recommendations on a barrel comparable to Criterion or if I could use a rifle length system for my 16” build ?

Thanks,
