BRVN Series

Button Rifling Machine

Precihole Button Rifling Machines incorporate state-of-the art features to form precision grooves in small caliber gun barrels. The rifling button is pulled and rotated precisely through the barrel. The machine uses anti-backlash helical guides and rotary encoders to interpolate linear and rotary motions. This combination produces highly precise twists in the barrel. Rifling operation is extremely fast at 40–50 IPM pull feeds.
