This Proof Research carbon-fiber PXT barrel blank in .284 caliber gives custom builders the foundation for a true lightweight precision rifle. Proof pioneered carbon-fiber-wrapped barrel technology: a match-grade stainless core wrapped in aerospace carbon fiber that sheds heat, cuts weight dramatically, and stiffens the barrel against stringing during long shot strings. At 22 inches in a Sendero contour, this blank suits 7mm builds from 7mm-08 to the big magnums. The choice of gunsmiths building mountain rifles where every ounce counts and accuracy cannot be compromised.
