Absolutely. I had Addax out of Los Angeles build me a custom 14.5" upper a few years ago, specifying a Sabre barrel, in fact. Their barrels are REKNOWNED for quality & accuracy.
Would love to have gotten a Sabre rifle before they went under. If a used one happened along, that hadn't been otherwise abused, much like a Charles Daly, I'd snap it up without a second thought.
