Description
The Steiner M7Xi M-Series 8717-T3 is a 2.9×20 x 50mm fixed-power riflescope from Steiner built on a 34mm tube with a Tremor 3 reticle in the first focal plane.
Steiner M7Xi M-Series 8717-T3 Overview
A fixed-power scope keeps things simple: fewer moving parts, less weight and nothing to forget to adjust, with a consistent sight picture every time you shoulder the rifle.
The trade-off is flexibility, so pick a power that matches the distances you actually shoot.
Optics and Reticle
Magnification runs 2.9×20 with a 50mm objective lens. The distributor lists a field of view of 12 – 1.78 meters @ 100 meters. The reticle is listed as Tremor 3.
Because the reticle sits in the first focal plane, it grows and shrinks with magnification, so holdover marks stay correct at every power setting. The trade-off is a reticle that looks fine at the low end and bold at the high end.
Turrets and Adjustments
Parallax: 50 yds to Infinity. Zero the turrets at your chosen distance and note how many clicks you need for longer shots.
Mounting and Fit
The 34mm main tube needs matching 34mm scope rings or a one-piece mount. Eye relief is listed as 3.23″ – 3.43″, so set the scope far enough forward that recoil cannot drive the eyepiece into your brow, then level the reticle and confirm you get a full sight picture with a natural cheek weld. Listed length is 13.80″.
Build and Durability
The tube is aluminum, finished in black, and the distributor lists it as fog / waterproof. Listed weight is 32.50 oz. Check ring screw torque after the first range session and again before hunting season.
Honest Limitations
Every scope involves trade-offs. More magnification brings a narrower field of view, more visible shake and more heat mirage on warm days, and a larger objective adds weight and height over the bore. Budget and mid-priced scopes can be excellent values, but their adjustments and low-light performance do not match premium glass, so match the scope to how and where you hunt or shoot.
Low-light performance depends on the objective size, coatings and your own eyes as much as the spec sheet, so compare scopes at dusk if you can.
Sighting In
Bore sight first, then fire a three-shot group at 25 yards to get on paper and move to 100 yards to refine. A 100-yard zero is the common starting point for centerfire hunting rifles, 50 yards for rimfires, and the distance your ballistic data assumes for long-range work. Confirm the zero with the exact ammunition you plan to use.
Care and Storage
Keep lens caps on in the field, clean the glass with a lens brush and microfiber cloth instead of a shirt tail, and store the rifle where temperature swings will not fog the optics. Recheck zero after any hard knock or after travel.
Before You Buy
Confirm the ring size, mounting height and the distances you shoot most. Riflescopes are not firearms and ship without an FFL transfer.
