Steiner 4-28 IFS - ballistic military scope with no compromises

Steiner latest contribution for military-type long-range shooting was unveiled few days ago in EnforceTac / IWA exhibition. We are very delighted to see development finally came into finalized product - and was probably a big surprise for almost all.

We are also happy to ensure that this is not only a concept or technology presentation made for just for show. Or product without true intention or capability to deliver. We have been behind scenes in long development phase already- and assure that this is real deal. We also recommend anyone who is planning to buy integrated ballistic scope in near future to try it, before making any decisions.

As far as we know, Steiner IFS is only integrated computer with feedback from both turrets, a feature which makes surprisingly big difference when using scope. It is also only riflescope with transparent matrix screen, a screen that is also very large covering almost half of entire FOV. IFS offers, quite exceptionally, true computing of whole trajectory based on all input variables- and it does it again in a split-second if any of variables change. This requires both very sophisticated software and CPU power.

All elements on integrated display are customizable. Objects can be moved, activated or de-activated to fit any user need best. FOV offers wide artificial horizon, showing tilt to user at all times based on very sensitive 3-axis sensor measurement. It can also communicate with external devices wirelessly. It will be very interesting to see what else brilliant people in Steiner will come up with. We may have some idea about it, but we wont tell :)


Obvious question is that "what this can do better than existing similar products?"

Beside ballistic engine and pure CPU crunching, this is a true military-grade scope withstanding 900G (!) impacts and other environmental requirements typical to mil-optics. It is extremely difficult (=expensive) to achieve such in practice. Electronic circuit board is naturally fragile component, as displays are too.

Scope is still shorter than existing M5Xi 5-25 scope, and weight is not more than 1150g - tad over 40oz. Eyepiece looks bulky in pics, but is not really that big when handling scope. Right side of eyepiece is actually very close to normal scope. IFS scope is shorter than current 5-25 scope and not much heavier either.

Scope is made with principle that user sees everything in FOV without need to look away from scope at basically any time. IFS, as well as normal M7Xi 4-28, will also be offered with new MSR2 which is more or less perfect fit for this type of riflescope too. Scope is providing elevation and windage solutions directly on field of view, but also turret postion feedback same time. There is no need for ballistic reticle, especially as fixed grid can not be as accurate as tilt/cant/weather corrected solution on screen already is.

MSR and particularly MSR2 work in very wide range of magnifications as new M7Xi 4-28x56 7x ratio scope requires.

IFS also has programmable milling reference screen for fast milling, showing any predefined object mrad size for distance where elevation turret is adjusted at any time. MSR with ultra-fine milling capability is very beneficial and natural extension for this feature. Reticle ranging measurement time decreases significantly, mrad size for set distance can be seen inside scope, without looking notes or making any additional calculations.

See upper photo, box on lower left. 1.7m tall objective size is 2.07mrad at 823m distance. Range as solution from elevation turret position: with current air pressure, temperature and weapon cant. Some may notice that mathematically correct result would be 821m - but IFS rounds it to closest 1/100 in mrads. 2.06 or 2.08 would cause more range error, it is sensible to keep mrad target size decimals limited to two for clarity.


We accept IFS reservations- see product in our webshop. Long wait guaranteed for those who are not reserving this on time!

    Cool, for all except competition shooters!
