Terminus Pre-Fit Barrels

DESIGNED FOR THE ENTHUSIAST

PROOF Research carbon fiber & steel pre-fit barrels for the Terminus Apollo, Zeus and Kratos actions come chambered and threaded for an easy install. Simply torque on, double check & ensure headspace with proper gauges and head to the range! Pre-fit barrels that deliver shot for shot accuracy and performance - there is simply no better choice for the Terminus Apollo, Zeus, and Kratos actions than our carbon fiber & steel pre-fit barrels.

Zeus: Pre-fits will fit actions with the "quick change" option but not the "full length" thread option.

Apollo / Apollo Lite / Ti: Pre-fits will fit all actions with integral recoil lug and actions supplied .250" thick recoil lug.

Kratos / Kratos Lite: Pre-fits will fit all actions with 1 1/16" x 16 receiver threads but not actions with 1.100" x 16 threads.

DISCLAIMER:
* All shouldered pre-fit barrels are guaranteed for headspacing.
* Due to variance in actions we do not guarantee the timing and alignment of the barrel engraving to your stock line.
* Barrels are specific to the action type/length and are not interchangeable.
