At the heart of the Impact SB is a 26" blued carbon-steel barrel featuring Thompson/Center’s QLA recessed crown for consistent bullet seating. The 1:28" right-hand twist stabilizes a wide range of .50 caliber projectiles, and the barrel is drilled and tapped to accommodate scope bases if you choose to add optics later.
The break-action inline system uses a tool-less Speed Breech plug, allowing quick removal for thorough cleaning in camp or at home. A tough, lightweight aluminum Power Rod ramrod stores under the barrel and is sized for the full-length tube.
Williams fiber-optic sights come factory-installed: a dual-dot green front ramp and an adjustable rear notch. These bright references make target acquisition straightforward in varied lighting conditions.
The black polymer stock is fully ambidextrous and includes a 1" removable spacer, adjusting length of pull from 12.5" to 13.5". An integral trigger guard, rubber recoil pad, and textured grip panels provide a secure, comfortable shooting platform.
Made in the USA and carrying Thompson/Center part number 10186680, this Impact SB offers a blend of modern engineering and classic black-powder performance in a clean, ready-to-shoot package.
