Proof Research Pre-Fit Bolt Action Barrel 6.5 Creedmoor 16.5" 1:7.5 Twist Sendero 5/8x24

The Proof Research Pre-Fit Bolt Action Barrel is a precision 6.5 Creedmoor pre-fit replacement barrel built for custom rifle builders and long-range precision shooters. Cut to a compact 16.5" length with a 1:7.5 twist rate, this barrel is optimized to stabilize the long, heavy match projectiles favored in 6.5mm precision shooting.

The barrel is profiled in Proof's heavy Sendero contour for the stiffness needed to deliver consistent harmonics and repeatable accuracy downrange. It features a 2.5" breech, a 1.20" shank diameter, and a 5/8x24 threaded muzzle ready for installation of your preferred muzzle brake or suppressor. At approximately 2 lbs 8 oz, it delivers the rigidity of a heavy contour in a manageable package for its size.

As part of Proof Research's pre-fit (PXT) line, this barrel is designed for drop-in installation on a compatible bolt action, giving builders a factory-accurate barrel without the lead time and cost of a full custom chamber-and-install job.
