3E KESKIN scopes and İZCİ: precision shooting optics
Quick answer: 3E Elektro-Optik’s precision shooting catalog consists of two families: KESKIN riflescopes and İZCİ spotting scopes. The KESKIN family holds six models, from the LPVO-class 1-8×30 up to the 6-36×56; the İZCİ line has the 15-45×60 and 20-60×80. The common architecture is a first focal plane (FFP) reticle, zero-stop turrets, and, per the manufacturer, recoil resistance up to 12.7 mm NATO. This file covers 3E’s KESKIN; it has no connection to identically named systems from other manufacturers.
Why does an FFP reticle matter?
A reticle in the first focal plane grows with the image, so the mil marks on the reticle measure the same real value at every magnification. A shooter who measures a hold at 10x does not have to change it at 25x, and a correction called by the spotter is applied regardless of the magnification setting. Five of the KESKIN family’s six models are FFP; the SF variant offers a second focal plane (SFP) and a hybrid MOA+MIL reticle for users who work in MOA units.
KESKIN family table
| Model | Magnification | Reticle | Elevation travel | Length / Weight |
|---|---|---|---|---|
| KESKIN 1-8×30 | 1-8x (LPVO) | FFP | 32+ MIL | 270 mm / 735 g |
| KESKIN 3-12×50 | 3-12x | FFP | 25+ MIL | 335 mm / 975 g |
| KESKIN 5-25×56 | 5-25x | FFP | 32+ MIL | Not disclosed |
| KESKIN 5-25×56 Ultra Short | 5-25x | FFP | 32+ MIL | 315 mm |
| KESKIN 5-25×56 SF | 5-25x | SFP, MOA+MIL hybrid | 90+ MOA | Not disclosed |
| KESKIN 6-36×56 | 6-36x | FFP | 32+ MIL | Not disclosed; 92%+ light transmission |
Across all models the manufacturer reports a 34 mm one-piece aluminum tube, zero-stop turrets with a second-turn pin, 11-level reticle illumination and IP67 protection. The Ultra Short variant shortens the body to 315 millimeters for users mounting a clip-on device in front; this is the direct counterpart of the use case with scope-front thermals such as the PARS SLR.
İZCİ: the spotter’s scope
The İZCİ 15-45×60 and 20-60×80 are tactical spotting scopes for the observer side of a sniper team. Both carry a MIL reticle in the first focal plane: the spotter measures the target with the reticle, and the mil value read matches the value in the shooter’s scope one to one. The body has standard top and side Picatinny rails; a night vision adapter, laser rangefinder or illuminator can be carried directly on the scope. The 15-45×60 model weighs 1,180 grams at 290 millimeters; the 20-60×80 reaches 60x magnification with its 80-millimeter objective. This measurement chain is completed by ballistic-computing rangefinders such as the MLRF-PRO.
Market context
The high-magnification military scope market is the territory of established brands such as Schmidt und Bender, Nightforce and Vortex, and Turkish sniper rifle manufacturers have covered their optics needs largely through imports. The KESKIN family is an attempt to build a domestic alternative in this line item; which rifle programs and units use it has not been officially disclosed. The manufacturer says the reticle patterns were developed with feedback from operational users. The company’s overall product strategy is covered in the company profile and all categories in the products guide; for the close-range side, see the reflex sight file.
Frequently asked questions
Is this KESKIN the same as FOTONIKS’ KESKIN system?
No. The KESKIN name is used on more than one product in the Turkish defense industry. The KESKIN in this file is 3E Elektro-Optik’s riflescope family; it has no connection to identically named systems from other manufacturers aimed at weapon stations.
What does a zero-stop turret do?
It mechanically prevents the turret from dialing below the zero position the shooter has set. The shooter can return to zero by feel, even in the dark; the second-turn pin separately marks the second revolution.
What is an LPVO, and what role suits the KESKIN 1-8×30?
An LPVO (Low Power Variable Optic) is a class of variable scopes starting at true 1x. It provides both-eyes-open close-range aiming at 1x and mid-range aiming at 8x, bridging the gap between infantry rifle and designated marksman roles.
Why does İZCİ use an FFP reticle?
So that the mil value the spotter measures stays valid at every magnification. Correction calls between spotter and shooter then run error-free, independent of either side’s magnification setting.
What calibers can KESKIN withstand?
The manufacturer reports recoil resistance for 7.62 mm NATO, 8.59 mm (.338) and 12.7 mm NATO (.50). No independent test data has been published.
