Proof Research carbon fiber-wrapped barrels are the gold standard for shaving weight from precision rifles without sacrificing accuracy, and this PXT-series AR-10 barrel brings that technology to large-frame gas guns. Chambered in 6.5 Creedmoor with a 20-inch length and cut for a .875 gas block, it pairs a match-grade stainless core with Proof's aerospace-derived carbon wrapping — stiffer and dramatically lighter than an equivalent steel barrel, with faster cooling under strings of fire. The centerpiece upgrade for a lightweight precision AR build.
