Description

Key Performance Highlights:

Fast 1:16 Twist Rate: Unlike the standard 1:24 twist, the Superior Heavy features a faster rotation specifically designed to stabilize long, high-BC (Ballistic Coefficient) slugs ranging from 25gr to 40gr+.

The 800mm Powerhouse: As the longest liner in the FX catalog, the 800mm version provides a longer “power stroke” for air expansion. This allows you to reach high FPS targets with lower regulator pressures, resulting in a smoother shot cycle and increased air efficiency.

Glass-Smooth Rifling: Utilizing FX’s patented “pressed-from-the-outside” Smooth Twist X method, the internal bore is free of the friction-heavy lands and grooves found in traditional barrels. This reduces lead fouling and ensures match-grade consistency.
