The Connecticut Valley Arms Endura Pro is a 45 caliber muzzleloader built around a bolt-action in-line design. The rifle measures 49.55 inches overall with a 26-inch barrel and weighs 8 lbs. 7 oz. It features a 1:22″ rate of twist and a synthetic stock finished in bi-tone Desert Camo, paired with a Cerakote-finished tungsten metal barrel. The stock incorporates a recoil pad and is drilled and tapped for scope mounting.
Performance and precision are supported by a Trigger Tech single-stage trigger, while the action benefits from nitride hardening. The barrel itself is fluted and threaded, manufactured by Bergara with a tungsten-lined breech plug. The bolt face is magnetic, and the stock is the BOA Eagle Pro model. Steel hardware is integrated throughout the design.
The Endura Pro is approved for use with BLACKHORN 209, Vihtavuori N120, and IMR4198 propellant charges, making it compatible with a range of modern muzzleloading powders.
