Description
A fixed 5.5x50 ACOG riflescope with a red chevron .223 / 5.56 BDC reticle, for users of 5.56 rifles who need magnified, illuminated aiming by day and night.
This Trijicon ACOG combines 5.5x magnification with a 50mm objective and a red chevron reticle with bullet drop compensation calibrated for .223 / 5.56.
The reticle is illuminated by fibre optics and tritium, and the brightness adjusts automatically to the available light.
The scope is supplied with a flattop thumbscrew mount, and the housing is forged aluminium with a matte black finish.
Key features
- Chevron zero and ranging — The chevron reticle is zeroed using its tip at 100 metres, and its 5.53 MOA base width allows range estimation for silhouette targets.
- Tritium and fibre illumination — Fibre optics and tritium light the red reticle, with brightness adjusting automatically to the available light.
- Bindon Aiming Concept — The Bindon Aiming Concept supports shooting with both eyes open for improved situational awareness.
- Fixed-power design — The fixed-power design keeps moving parts to a minimum for a robust sighting system.
- Multi-coated lenses — Multi-coated lenses maximise light-gathering and give a clear field of view.
- Shock-resistant — The scope is proven to withstand recoil from a .22LR to a .50BMG.
- Waterproof, nitrogen-filled — The waterproof housing is filled with dry nitrogen to mitigate fogging in extreme cold and heat.
Typical applications
- Magnified day and low-light aiming on .223 / 5.56 rifles.
- Range estimation and holdover on silhouette targets at extended distances.
- Duty and professional use where a robust, self-illuminated optic is required.
