Proof Research Sendero 243 Win 18" Carbon Fiber Barrel Blank 1:7.5 Twist

Proof Research Sendero Barrel Features The Proof Research Sendero barrel blank is built around a stainless steel core wrapped in carbon fiber a construction method Proof Research uses across its match grade barrel lineup to cut weight without giving up the rigidity a precision barrel needs. Chambered as a blank in .243 Win it measures 18 inches long with a 0.972 inch outside diameter and a 1:7.5 inch twist rate suited to stabilizing the heavier for caliber bullets .243 Win shooters favor at longer range. The 4 groove rifling is machined to the same tight tolerances Proof Research applies to its finished barrels supporting consistent bullet engagement shot after shot. Because this is a blank a gunsmith chambers and threads it to the builder s own specification during fitting. Carbon fiber wrapped barrels dissipate heat differently than bare steel helping the barrel resist the point of impact shift that can occur as a steel barrel heats up during a long string of fire. The reduced weight at the muzzle end also makes a carbon fiber barreled rifle noticeably easier to carry and hold steady offhand compared to an equivalent steel profile. Proof Research has built its name on this exact combination of carbon fiber technology and match grade accuracy making its barrels a common choice among custom rifle builders. This Sendero blank gives a builder the foundation for a lightweight accurate .243 Win rifle without compromising on barrel quality.
