Superior Heavy Slug Liners (.177 Pre-Order)
Regular price $109.00
This liner is highly recommended in order to get the best results with heavier grain slugs. In our preliminary testing we have found this liner shoots pellets very well. It has also been found it shoots Nielsen Specialty Ammo Slugs just as well, or better, as the STX Slug A Liner.
The groundbreaking Smooth Twist X barrel liner has been further perfected. FX Airguns proudly introduces the new FX Superior Smooth Twist X Barrel Liner (or FX Superior STX). The new Superior STX barrel liners are still created using the patented way of pressing the rifling into the barrel from the outside; but this is now done with a higher degree of precision, lower tolerance, and some other slight modifications that result in a superior liner to the standard STX liners.
