Alfa Precision · Standard Barrel · Blank · Cal .177 (4.5mm)

This barrel blank is manufactured for gunsmiths and precision airgun builders requiring a reliable, conventional rifling profile. 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.
• 370mm twist rate (1:14.6): calculated for stabilization of .177/4.5mm caliber pellets across standard PCP velocity ranges.
• 12 grooves (N=12): balanced contact surface for consistent sealing and controlled wear.
• 700mm length: supports extended barrel time for efficient air-to-velocity conversion.
• 16mm OD: compatible with a range of action and shroud configurations.
• 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.
