R-Series Rifling Machines

Accuracy and control in the rifling process create accuracy and control in finished rifle barrels. R-Series refling machines use fully programmable twist rate for rifling, powered by servo-driven motors, and closed loop feedback to put unmatched manufacturing control in the hands of operators. Manufacturers are able to produce exceptional barrels in higher quantities, with intuitive technology and choice components.

R-Series rifling machines have a compact footprint with minimal installation, automatic tool lubrication, and available robot-ready or full automation. Machines utilize button rifling across all calibers of barrels, for precision rifle grooves. Intuitive operation allows rifle manufacturers to push the limits of rifle barrel technology with unmatched confidence.

UNISIG Rifling machines require an export license and may not be available in all areas.
