FX Airguns Superior Heavy Liner – 700mm, .22 Caliber

For shooters aiming to optimize performance with heavier grain slugs and pellets, the FX Airguns Superior Heavy Liner in 700mm, .22 Caliber comes highly recommended. Designed to excel with projectiles requiring a faster twist rate for stabilization, this liner is a game-changer for precision shooting.

Its performance is especially notable when compared to standard liners, making it the ideal choice for shooters seeking superior accuracy and consistency.

Building upon the success of the groundbreaking Smooth Twist X barrel liner, FX Airguns has further perfected their design with the introduction of the FX Superior Smooth Twist X Barrel Liner (or FX Superior STX). While still utilizing the patented method of pressing rifling into the barrel from the outside, the Superior STX liners boast enhanced precision, lower tolerance, and other subtle modifications.

Whether you’re a competitive shooter, a hunting enthusiast, or a recreational marksman, these advanced liners provide the precision and performance needed to take your shooting to the next level.

In conclusion, the FX Airguns Superior Heavy Liner and Superior STX barrel liners represent the pinnacle of barrel technology, offering shooters unparalleled performance with heavier grain slugs and pellets.
