Introducing the all-new SIS2 Sight. The SIS2 is an advancement of the SIS sight providing the following new features:
•Larger Viewing Window
•Streamlined exterior silhouette for more compact profile
•Upgraded internal LED giving better changeability and overall brightness

The Shield Switchable Interface Sight (SIS) is a compact, lightweight ruggedized reflex sight designed for rapid target acquisition at close combat distances and capable of operating under the harshest military environmental conditions. The SIS is an advancement on the CQB sight, combat proven with over 45,000 units in use by the British military. The SIS was designed with real-world application input from Special Forces, Law Enforcement and Military users. 

The SIS sight is manufactured in England using hard anodized aluminum construction. Smaller and lighter than the competition, at just 2oz and just 2” x 1.5” x 1.1” in size, the SIS is a versatile sight optimal for a variety of uses including: as a primary optic, offset rifle mounts, offset scope mounts, and in conjunction with magnified optics. The SIS features a switchable reticle system (1MOA, 8MOA, 1MOA & 65 MOA Ring, 8MOA & Ring), allowing the user to change reticles depending on the type of firearm being used or to tailor to mission requirements. Being an enclosed sight, it can be used in the rain without worry of water getting between diode and lens

The brightness is controlled automatically based on ambient light conditions, however it can also be adjusted manually via side buttons to fit user requirements. In order to minimize the visual signature, the SIS is designed without a red reflective filter on the lens.

The SIS has a streamlined design to prevent snagging of body parts on slings, harnesses, vegetation, etc. The SIS includes a variable height picatinny mounting system, allowing the user to adjust the height of the SIS for optimal check weld on various system platforms, to co-witness with iron sights or align with a magnifier.

Comes with variable height picatinny mount, dust cover, battery, and manual.
