Alfa Precision · Standard Barrel · Blank · Cal .25 (6.35mm)

This barrel blank is manufactured for gunsmiths and precision airgun builders requiring a reliable, conventional rifling profile in .25 caliber. The standard groove configuration provides consistent pellet engagement and repeatable ballistic performance across a wide range of PCP platforms.

Technical Benefits

• Standard rifling profile: proven groove geometry for consistent pellet engagement and predictable performance.
• 10 grooves (N=10): balanced contact surface for consistent sealing and controlled wear.
• 450mm twist rate (1:17.7): calculated for stabilization of .25/6.35mm caliber pellets at standard PCP velocities.
• 650mm length: compact configuration suited for a range of PCP platforms.
• Unfinished blank: supplied without external profiling, threading, or crowning, allowing full customization to the builder's specifications.

Specifications

Installation requires machining, fitting, and finishing by a qualified gunsmith. This is a raw precision component, not a finished, ready-to-install barrel assembly.
