Description
A 4x32 ACOG ECOS combined with a 3.25 MOA RMR Type 2 red dot, for professional users who need both close-quarter speed and magnified precision on one rifle.
This dual-sighting system pairs a fixed 4x magnified ACOG with a 32mm objective and an RMR Type 2 red dot mounted on top, so the shooter can choose between quick target acquisition and precise aiming for the situation at hand.
The ACOG uses a green crosshair reticle with bullet drop compensation for 5.56 (Caliber 0.223), illuminated by fibre optics and tritium without batteries; the RMR adds an automatic LED 3.25 MOA red dot.
It is supplied in Flat Dark Earth (FDE) on a Trijicon Quick Release Mount, together with a set of backup iron sights.
Key features
- Two sighting options — The shooter can switch between the RMR Type 2 for close quarter battle and the magnified ACOG for longer distance shooting.
- Battery-free ACOG reticle — The tritium and fibre optic illuminated reticle is battery free and adjusts its brightness automatically to the available light.
- Bindon Aiming Concept — The Bindon Aiming Concept allows both-eyes-open shooting for improved situational awareness.
- External adjusters — External windage and elevation adjusters mean no tools are needed for windage and elevation adjustments.
- Rugged fixed-power design — The fixed-power design keeps moving parts to a minimum in a forged aluminium housing.
- Shock resistant — The sight is proven to withstand recoil from .22LR to .50BMG.
- Fog-free housing — The dry nitrogen-filled housing eliminates fogging and is tested for extreme cold and heat.
- Multi-coated lenses — Multi-coated lenses maximise light-gathering capability and give a clear field of view.
Typical applications
- Service and duty rifles that must cover both close-quarter and longer-distance engagements.
- Law enforcement and military units standardising on a single combined optic.
- Professional shooters who want quick transitions between magnified and red dot aiming.
