STEINER 5117 T6XI 2.5-15x50 Tactical Rifle Scope - MOA Reticle

The Steiner T6XI 2.5-15x50 tactical rifle scope brings serious versatility to carbines and bolt guns that need to reach from close quarters to distance. Built in the USA, this first focal plane scope spans a 6x zoom range—from 2.5x for quick target acquisition in tight spaces to 15x for precision work downrange—making it equally at home providing overwatch or engaging targets across unpredictable terrain. The 50mm objective and 34mm tube diameter strike a practical balance between light transmission and ruggedness without excess weight.

What sets the T6XI apart is its attention to shooter feedback and consistency. The low-profile, never-lost locking turrets eliminate the guesswork: an innovative second rotation indicator tells you instantly when you've turned a full revolution, so you stay oriented even during rapid adjustments. The resettable zero elevation knob and 1 cm (0.1 mrad) click value let you dial in adjustments with confidence, backed by 60 MOA elevation and 50 MOA windage range at 100 meters—enough travel for most hunting and tactical applications. The side-focus parallax adjustment spans 25 yards to infinity, keeping the sight picture sharp across real-world distances.

A four-level nighttime and seven-level daytime illumination system handles low-light hunts and bright-sun range days. The scope is fully waterproof (submersible to 33 feet), fogproof, shockproof, and filled with nitrogen to resist environmental stress. At 12.8 inches long and 32 ounces, it's compact enough not to throw rifle balance but substantial enough to take hits in the field. The SCR-MOA reticle is clean and functional—no clutter, just aiming points that work.

Whether you're running a hunting rifle or a defensive carbine, the T6XI delivers the optical performance and mechanical reliability Steiner built its reputation on. This is a scope that doesn't ask you to choose between power and speed.

Specifications

Frequently Asked Questions

Is the Steiner T6XI compatible with my rifle?

The T6XI works on any rifle with a 34mm scope mounting system—carbines and bolt-action rifles alike. The compact 12.8-inch length fits most setups without overhang.

What does "first focal plane" mean for my shooting?

In a first focal plane (FFP) scope, the reticle sits in front of the magnifying lens. That means the reticle scales proportionally with magnification: your holdover marks remain accurate no matter what power you're zoomed to. This is especially useful for variable-power scopes like the T6XI, where you might jump from 2.5x for a quick shot to 15x for a distant target.

How durable is this scope in the field?

The T6XI is waterproof to 33 feet, fogproof thanks to nitrogen filling, and shockproof—built to handle wet weather, temperature swings (−13°F to +145°F), and the recoil of centerfire rifles. Steiner manufactures it in the USA to strict standards, and the locking turrets stay locked through rough handling.

Can I use the illuminated reticle in daylight?

Yes. The illumination control features seven daytime levels specifically for bright conditions, so you can dial in the brightness that works for your situation without washing out the reticle.
