Description

The Proof Research 104514 is a precision bolt-action rifle barrel chambered in .243 Winchester, designed as a drop-in upgrade for custom rifle builds and a full-length replacement for worn factory barrels.

Featuring an 18-inch Sendero contour, this barrel is cut with a 1:7.5 twist and 4-groove rifling, stabilizing a broad range of projectile weights from light varmint loads through heavier hunting bullets. The assembled barrel measures 25.2 inches in total length, giving gunsmiths and builders a generous profile for predictable harmonics and consistent accuracy.

Constructed with Proof Research’s signature carbon fiber wrapped barrel technology, the 104514 weighs approximately 3.6 lbs and is rated up to 64% lighter than comparable traditional all-steel barrels. This advanced design delivers excellent heat dissipation during extended strings of fire and is engineered for precision shooting applications, making it an ideal choice for hunters and long-range shooters seeking reduced weight without sacrificing accuracy or barrel life.
