Special variant for left handed shooters. On this device the target focus knob is placed on right side of objective lens housing making it easy to reach for lefty’s.



Let’s face it, sometimes things get up close and personal. Having a secondary red dot sighting system mounted in tandem with your Fusion Thermal sight provides a fast and efficient aiming point for close targets. And we’ve made it easy by designing our thermal optic mounts in conjunction with our friends at UNITY Tactical to be compatible with their FAST™ system Offset Optic Base and Offset Adapter Plates, allowing you to mount a secondary red dot right to your thermal optic. When the need arises, simply cant the rifle 35% and rock & roll.

The FAST™ Offset Optic Mount includes both the base and optic adapter plate, everything you need to mount your red dot optic to the Fusion Thermal unit. Each plate comes with a specific optic footprint and uses the optic manufacturer’s hardware. Each plate footprint will accept any mini red dot with that footprint pattern. Plates can mount in three positions on the Offset Optic Base (forward cantilever, centered, rearward cantilever) for a customized fit.

It’s been nearly a decade since thermals scopes started becoming affordable to the average Joe, and since that time there has always been a keen interest in the clip-on concept. It seems like the perfect way to go. You can deploy it when you need it and keep it concealed when you don’t. You can move it around from one rig to the next in a matter of minutes offering maximum flexibility to meet changing needs. If designed right it also offered some really great secondary uses like as a handheld observation device. It all seems so perfect. Problem is they just have not performed up to the promise, so adoption of the clip-on by the American shooter has been slow to come. Well, my friends we’re happy to tell you that the clip-on has come of age. Enter the Recon 55XR and its groundbreaking optical system called MORE (Magnification Optimizing Range Enhancement). This new technology brings clip-on performance into the modern era buy solving the biggest hindrance to clip-on mass adoption, that of being forced to use your clip-on on the lowest magnification settings of your day scope. Gone are the days of using your clip-on with your day scope on 3X and acting happy. The MORE optical system unleashes the full potential of the clip-on concept by allowing you to use significantly higher levels of magnification, usually by a factor of two, occasionally more.
Sometimes it takes years of obsession and serious brain power to make significant technology breakthroughs, but once the barriers are broken great things happens. If your intrigued and want to know more about what the Recon 55XR might do for you, we invite you to take deeper dive into the information we’ve provided. You just might find that the moment you’ve been waiting for has arrived.
This variant is optimized for right handed shooters.



It would be hard to overstate the level of performance unleashed by the Boarmaster 55XR. This big brother in the Boarmaster family brings to bear our upsized 55mm Arclight Ultra HD Germanium Lens and our flagship WAVE12 sensor with 640×512 resolution. There is so much here that stacks the deck it hard to find a beginning point without sounding like we’re bragging. However, all great things must have a start so here we go.

You can expect everything common to the Boarmaster product line and that begins with our T3 -Three Button Control System that allows you to operate everything with three buttons. This ingenious design features a center tower that always gives your fingers a position operational awareness, even in complete darkness. Our English language KISS (Keep it Simple Stupid) operators’ menu is so easy to understand you’ll likely never read the manual.  The Micro Click Focus system allows for an unprecedented focus opportunity that gives you the ability to get precisely on top of the perfect focus point. Finally, our XGEN Next Generation Alloy Housing wraps your expensive device in a clad of armor and dissipates heat 71,900 % better than plastic and fiber filled epoxy plastics.

The Boarmaster 55XR truly delivers a thermal experience uncommon for what’s commercially available. Your only mistake may be looking thru one if you didn’t plan on owning one!

Our premium Avenger 35 is the stallion of our dedicated thermal scope line.

Rusan Adapters are a simple and effective way of attaching a thermal clip-on device to your scopes objective bell. Once the adapter is screwed on to your thermal clip-on you simply slip it over the front lens of your scope and move the lever to the clamp closed position. The attachment takes just a few seconds. The Rusan adapter slips over approximately 1.4” of your objective lens so there’s lots of clamping surface area for a great hold. The inside of the adapter is lined with a special film to provide for extra gripping power and assures a scratch free attachment.

Important Notice
It is the outside diameter of your scope lens housing that determines the adapter size needed, not your lens size.
For example, Swarovski scopes with 50mm objective lenses have an external housing diameter of 56mm. For a Swarovski 50mm scope you would need Rusan Adapter Model: ARM52-56. It is the last two numbers in the product SKU that indicate adapter size.
Call before ordering if you have unresolved questions.
