Accuracy test for multiple groups of shots using a competition Biathlon Rifle
The Ace models are built with high quality optics that provide sharp and high resolution viewing in various conditions. The fully multi-coated optics with green tint was designed to improve the light transmission coefficient in order to achieve a brighter, clearer image in sunset or sunrise environment. The robust d30mm mono-tube scope body is milled from one solid piece of aircraft aluminum and finished in matte black to prevent undesirable reflections.
The sights feature illuminated switchable reticle, red or green, with five brightness settings. The sights may be used without a battery. The reticle is black in off position. The Ace sights have a side focus parallax adjustment mechanism that allows parallax correction from 10 yards (meters). The parallax correction wheel is included with the sight to make the adjustment precise and convenient. The parallax correction wheel has specially designed grooves to avoid off-set positions when it is set up and in use.
All adjustment mechanisms such as focus, windage and elevation have been perfected to have smooth and pleasant action to make the sights use satisfactory. Optional accessory includes a 3" (77mm) sunshade BE55901 to prevent glare in sun bright conditions.
