A: An "Occluded Eye Gunsight" works because of the brain's ability to "blend" the red dot in the sight with the object that you are sighting at. This is a function of "binocular vision" that we posses. It is important to note that both eyes remain wide open while sighting allowing for maximum peripheral vision.
Q: Do the Armson O.E.G. sight requires batteries?
A: No. Armson sights use a fiber optic light collecting element, and do not use batteries. Tritium models are also available to provide additional self powered illumination in low level light conditions.
Q: Do Armson O.E.G. sights contain Tritium?
A: Armson OEG sights were produced without Tritium for a period of time but are now available either with or without Tritium. A Tritium upgrade is available for O.E.G. sights originally purchased without Tritium.
Q: Can you replace the Tritium element in my older Armson sight if it becomes dim?
A: Yes. Tritium replacement service is now available. There is a downloadable Return Form with additional information on the Tritium Upgrade page.
Q: How long does Tritium continue to illuminate the dot?
A: Typically 12-15 years at which point the Tritium can be replaced by our service department for a small fee.
Q: How durable are Armson O.E.G. Sights?
A: Armson Sights are designed and built to exacting Military standards, and are considered virtually indestructible under normal operating conditions.
Q: What is the difference between the new Armson sights and the Armson sights from Trijicon?
A: There is no difference. Trijicon became a distributor of Armson sights in 1981 +/- and was the primary distributor in North America until approximately 2000. They did an excellent job of originally introducing Armson to the U.S., as well as maintaining a high standard of customer service during that time.
Q: Did Armson build the Singlepoint sight?
A: No, the Singlepoint was produced by Normark (an aircraft manufacturer, in England). The founding partner of Armson was involved with Normark, and moved to South Africa to develop the O.E.G. as an improved version of the Singlepoint after production had stopped in the mid-1970s. The Armson O.E.G. is the most similar, fully functional, sighting system of the Singlepoint "type" currently available.
Q: How are O.E.G. sights "sighted in"?
A: The O.E.G. (Occluded Eye Gunsight) sight must be used with both eyes open at all times. The user must concentrate on the target not the sight when aiming.
Ensure that the mounting system is correct for your weapon and that the sight is secured firmly in place before operation.
Prior to final zeroing, practice raising the weapon with both eyes open and placing the red dot on the target until it can be done quickly every time. This will save time and ammunition.
The small flat head screw in the center of each adjuster may need to be loosened slightly until the adjuster can be turned by hand.
At a range of approximately 25 yards (depending upon weapon type, and the expected range at which the target will be engaged), raise the weapon, place the spot on the target and fire immediately. The sight is then adjusted up or down and then left or right until the hits are in the center of the target (*see below). The range may be moved to 50 or 100 yards for final zeroing if it is required. When zeroing is complete, re-tighten the locking screw in the center of the adjusters.
*Turning the side Windage Knob CLOCKWISE will move the point of impact to the LEFT. Turning the Top Elevation Knob CLOCKWISE will move the point of impact DOWN. Turning either Knob COUNTER CLOCKWISE will produce the opposite result.
Dry fire practice is very beneficial and will improve skill without using ammunition. Remember that you must fire immediately when the dot is on the target.
