Moderator End Caps
Moderator End Caps
Our moderators ship with end caps threadlocked in place for secure use. Swapping end caps is the most direct way to move a moderator between rifles with different thread standards, or to switch between aluminum and POM/Delrin for weight savings. Replacement and alternate-thread caps are available individually, with an optional soft-jaw removal tool for extracting threadlocked caps without damaging them.
Key Features:
Multiple thread standards: 1/2-20 UNF, M14x1.25, M18x1, M20x1, and M10x1 available; front caps in aluminum and POM/Delrin
Two material options: Aluminum for durability; POM/Delrin for weight savings
Threadlocked from factory: Caps are secured to prevent backing out during use and moderator removal; included removal tool required for cap changes
Included removal tool: Soft-jaw vise tool with depth stops grips only the end cap; prevents damage during threadlocked cap removal
The easiest way to run one moderator across multiple rifles with different thread standards. Select your thread and material, and add the removal tool if you don't already have one.
