R-Series Rifling Machines

Accuracy and control in the rifling process create accuracy and control in finished rifle barrels . R-Series rifling 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.
