Truglo Eminus 3-9x42mm Tactical Rifle Scope, Illuminated TacPlex Reticle, 30mm Tube, Black Hardcoat Anodized

The Truglo Eminus 3-9x42mm tactical rifle scope brings accurate, practical optics to modern sporting rifles without unnecessary complexity. Built for shooters who want repeatable precision and easy adjustments in the field, this 30mm tube scope pairs quarter-MOA locking turrets with an illuminated reticle designed to track shots and dial elevation changes without cluttering your sight picture. Whether you're dialing for distance on a precision build or making quick holdover calls at distance, the Eminus gives you the adjustment range and clarity serious riflemen expect.

The 3-9x magnification range and 42mm objective lens strike a practical balance—enough power for target work and longer shots, enough light gathering for early morning and late afternoon hunting. Multi-coated optics cut glare and boost contrast, while the 30mm main tube opens up turret adjustment travel and brightness compared to smaller tubes. The scope is filled with nitrogen to defeat fog, sealed against water and impact, and finished in hardcoat anodized matte black that won't flash in the field.

Each turret click equals one quarter-MOA, making it simple to track your dope and communicate adjustments. The Illuminated TacPlex Reticle is calibrated in MOA so your holdovers stay true. A leaf-spring turret mechanism gives positive, responsive feedback with each adjustment, and the included APTUS-M1 mount positions the scope ideally on modern rifle platforms. Generous eye relief and side focus adjustment (20 yards to infinity on the variable-focus model) round out an optic that respects your time and your rounds.

Frequently Asked Questions

What caliber rifle will this scope work on?

The Truglo Eminus is a 30mm tube scope compatible with modern sporting rifles and precision builds. It is not caliber-specific; the optical design and turret adjustments work across rifle platforms. Confirm that your chosen mount interfaces properly with your rifle's receiver.

Is the reticle illuminated, and does it require batteries?

Yes, the illuminated TacPlex Reticle (T.P.R.) is illuminated. The details on battery type and runtime are not specified in the available product information—contact Bosque Outdoors for those specifications.

What is included with the scope?

The Truglo Eminus comes with an APTUS-M1 mount, which is designed for secure positioning on modern sporting rifles. This eliminates the need to source a separate mount for compatible platforms.

What is the difference between the side-focus and fixed-focus versions?

The side-focus model (TG8541TLR) includes a side focus dial that adjusts from 20 yards to infinity, allowing you to fine-tune the image clarity for different shooting distances. The fixed-focus version (TG8539TLR) is set at the factory and does not adjust. Choose the side-focus model if you shoot at varying distances or demand maximum image sharpness across your range.
