Compatibility Specifications
Zeus Action Compatibility
Pre-fit versions for the Zeus action accommodate the "quick change" feature, though they are not suited for the "full length" thread design.
Apollo and Apollo Lite, Ti Features
The Apollo variants fit actions with an integral recoil lug and those supplied with a .250" thick recoil lug, ensuring secure marriage between barrel and action.
Kratos and Kratos Lite Adaptability
Pre-fit barrels for the Kratos series support 1 1/16" x 16 receiver threads but are incompatible with 1.100" x 16 threading. This ensures precise alignment and reliable headspacing.
