System description

The Aries MK 258 is the 1st generation night vision “Smart Scope”. It is affordable and it has all of the standard “ Smart” features. Compact and light it is the perfect scope for every person who is willing to spend under $1000 for a good night vision scope. Its cousin the Aries Mk 238 has been sold in thousands over the past year and performed tremendously for all of our customers since its introduction. Besides the obvious technological advancements of the “ Smart Series”, the Aries Mk258 features several more improvements over the Mk 238.
The front lens optical system has been upgraded to a 90mm lens from a 50mm lens. Normally this would result in a loss of light amplification, however we have designed the 90mm lens specifically for our night vision scope and there is no visible loss of light gain.
Instead it provides an improved 4x magnification with sharp resolution, and without major increase in size or weight. Higher light amplification has been achieved by a new high-voltage power supply using digital technology.
Adjustments have been added for light amplification, infrared intensity, and lit-reticle brightness.
The Aries Mk258 still features the same dependable lit-reticle system of its earlier cousin, as well as internal adjustment for elevation and windage. It is made up of high-impact aluminum compound, and uses only top of the line glass optics. Mounting the Mk258 is a piece of cake, since it easily mounts to any standard 7/8” rail. Camera adaptable and ready for action, the Aries Mk258 is an impressive weapon sight in anyone’s dictionary.
