.204 Ruger TW-305 GR-6 Barrel Push Rifling Button

Barrel Push Rifling Button – Combination Tool

A precision-engineered tool designed for cold forming rifling grooves and land geometry in firearm barrels through push rifling. This combination button integrates multiple functional sections in a single pass to ensure optimal bore quality and performance.

Tool Components:

• Pilot Section: Ensures axial alignment and smooth entry into the barrel bore.
• Grooves Forming Section: Cold-forms rifling grooves to exact twist rate and depth specifications.
• Lands Diameter Calibration Section: Precisely sizes and smooths land diameters, ensuring consistent bore dimensions and superior surface finish.

Applications:
Used in the manufacturing of precision firearm barrels where uniformity and repeatability of rifling geometry are critical for ballistic performance.
