Steiner M7Xi 2.9-20x50 34mm Rifle Scope - Matte, Illuminated Tremor 3 Reticle, Side Focus
The Steiner M7Xi 2.9-20x50 34mm rifle scope is a versatile optic built for hunters and precision shooters who need both close-range clarity and extended magnification in a single package. The wide 2.9x to 20x zoom range lets you dial in on targets from intermediate distances all the way out to long range, making it equally at home on a hunting rifle or a competition platform. The 34mm tube and 50mm objective give you light-gathering power and optical quality that punches above its weight class, while the matte finish keeps reflections out of an adversary's eye—or simply looks right on a working rifle.
Built with a first focal plane design, the Tremor 3 illuminated reticle stays true for holdover and wind calls at any magnification, a genuine advantage when you're ranging past 300 yards. The side-focus mechanism puts parallax adjustment right where your trigger hand naturally reaches, eliminating the fumble of turning a bell on the back of the scope when you're already behind the gun. Illumination lets you use the reticle in low light without abandoning your zero.
Steiner's optical pedigree—German engineering married to real-world durability—means this scope handles the abuse hunters and shooters dish out. Whether you're glassing from a treestand, making precision shots across a canyon, or working steel at the range, the M7Xi delivers the magnification range and brightness you need without unnecessary bulk.

Frequently Asked Questions
What is first focal plane and why does it matter?
First focal plane (FFP) means the reticle sits in front of the erector lens, so it magnifies along with your target. That means your reticle subtensions—the dots and lines you use for holdovers—stay accurate at any magnification setting. This is crucial for long-range hunting and precision shooting where you're dialing in wind and elevation at different powers.
What's the advantage of a side focus knob?
A side focus (side parallax) adjustment is faster and more intuitive than turning a rear bell. Your hand is already near the side of the scope body, so you can tweak parallax without shuffling your grip or moving your eye from the reticle. This matters when you're ranging different distances quickly or setting up for a precision shot.
Is the reticle illuminated, and when would I use it?
Yes, the Tremor 3 reticle has illumination. You'll use it in low-light hunting situations—dawn, dusk, or overcast days—where the reticle would otherwise disappear against a dark target. Illumination doesn't change your zero; it just makes the reticle visible when ambient light is weak.
What hunting or shooting applications is this scope suited for?
The 2.9-20x range makes it flexible across hunting scenarios—2.9x is low enough for closer brush hunting or running distances, while 20x handles long-range shots across canyons or open country. Precision shooters and competitors also favor this zoom range for both close-range and extended-distance accuracy.
