Rival Arms Channel Liner Features The Rival Arms Channel Liner is built from a tough polymer material that stands up to the repeated friction of slide cycling without breaking down. Because it sits directly in the slide channel it acts as a buffer between the slide and frame rail helping to cut down on the metal shavings and wear marks that build up over time on a bare Glock frame. That reduced wear can help preserve a smoother quieter cycle across the life of the pistol. For competitive shooters and daily carry owners alike protecting the rail surfaces means more consistent function round after round. Each pack ships with five liners giving an owner or armorer enough supply to service more than one pistol or to keep spares on hand for future maintenance. The liner is molded in black to blend cleanly with factory Glock finishes and requires no special tools to install. Because it is purpose fit for Glock platforms installation is straightforward for anyone comfortable with basic pistol maintenance. This small upgrade is a practical low-cost way to extend the service life of a Glock slide and frame.
