I'm able to buy a new Proof Research prefit steel barrel for my AI AX short action for under $500. Specs are it comes threaded 5/8×24, 24" barrel, chambered in 6.5 Creedmoor. I know a lot of guys rave about their carbon wrapped barrels, but I haven't seen much talk about their all-steel barrels. Any reviews? Good? Bad? Indifferent?
