The Premium Standard for Modern Custom Actions

The Terminus Zeus has developed a reputation as one of the most innovative and refined custom rifle actions on the market.

Built around a Remington 700 footprint and featuring Terminus’ patented Quick Change barrel system, the Zeus allows shooters to swap barrels without the need for a barrel vise, action wrench or gunsmith intervention.

For shooters wanting one action capable of supporting multiple cartridges and barrels, few systems offer the flexibility of the Zeus.

Quick Change Barrel System

The defining feature of the Zeus is its:

Patented Quick Change Barrel Interface

Unlike conventional actions that require specialised tooling to remove and install barrels, the Zeus allows users to install pre-fit barrels quickly and securely using its integrated locking system.

Benefits include:

✔ Fast barrel changes
✔ No barrel vise required
✔ No action wrench required
✔ Repeatable installation
✔ Simplified calibre changes
✔ Reduced downtime

Many Zeus owners regularly swap between calibres and report highly repeatable return-to-zero performance when reinstalling barrels.

The Long Action platform provides maximum flexibility for modern long-range hunting and ELR cartridge families.

Controlled Round Feed Reliability

Unlike many modern custom actions, the Zeus incorporates:

Controlled Round Feed (CRF)

Benefits include:

✔ Positive cartridge control
✔ Reliable feeding under stress
✔ Consistent extraction
✔ Improved reliability from awkward shooting positions
✔ Exceptional hunting performance

This feature has made the Zeus particularly popular among serious mountain hunters and precision rifle shooters.

Providing:

• 60° bolt throw

DLC-Coated Components

Both the receiver and bolt are finished with:

Diamond Like Carbon (DLC)

Advantages include:

✔ Reduced friction
✔ Improved corrosion resistance

The DLC treatment contributes significantly to the renowned feel of the Zeus action.
