7.62x25 Tokarev / 7.62х39 / 7.62х54 R.M.N. TW-240 GR-4 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.

Calibre 7.62x25 Tokarev / 7.62х39 / 7.62х54 R.M.N. TW-240 GR-4

Twist mm: 240
Grooves: 4
Pilot dia.: -0.2 mm undersize Land dia.

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.
