Rusan Adapters – The Best Way to Run a Clip-On Thermal
G'day legends, Woody here, back on the range with something seriously cool. If you’ve seen my previous review of the Pulsar Krypton 2 XG50, you already know how impressed I was with its performance when rail-mounted in front of the scope on my Wedgetail Industries MPR308. That setup worked a treat — I dropped deer without issue and found the system to be incredibly reliable. But now… I’ve found something even better.
Introducing the Rusan Adapter System
The Rusan adapter setup has completely changed the way I run my clip-on thermal. Instead of using a clunky rail-mount system, the Rusan system gives you a quick-detach, return-to-zero mounting solution that clamps directly onto the objective bell of your day scope. It’s made up of two parts:
-
The adapter interface that connects to the thermal (in this case, the Pulsar Krypton 2), and
-
The clamping collar that snugly fits around the front of your riflescope.
These two parts lock together with a satisfying twist using Rusan’s cam-locking ring, and just like that, your thermal is mounted — solid, centred, and zeroed.
Return to Zero? Absolutely.
I put it to the test right there on the range. I fired a cold shot with my day optic to confirm zero — nailed it. Then I clipped on the Krypton 2 using the Rusan adapter and took another shot. Bang — dead on.
No re-zeroing. No fiddling. Just on target straight away. That’s what makes this system a game-changer. Whether you’re running pigs at night or taking long shots at first light, being able to quickly clip on and stay zeroed is invaluable.
Fast, Simple, Repeatable
What I love most about the Rusan system is its simplicity. The locking ring system is easier and faster to use than any rail-mounted setup I’ve tried. It always goes back into the exact same position, which means confidence every time you engage. You can mount it, shoot, unmount it, and repeat — all without worrying about shift or alignment issues.
Versatile for Spotting Too
The Krypton 2 comes with an eyepiece, and Rusan even makes an adapter so you can keep the Rusan interface installed on the thermal while still using it as a monocular. No more unscrewing bits and swapping parts — just a seamless switch from scope to handheld and back again.
Why This is Now My Go-To Setup
I’ve used a bunch of thermal mounting options over the years, but this Rusan setup is by far my favourite. It’s faster, lighter, and more intuitive than rail-mounting, and the ability to return to zero every time is a huge confidence booster when you're out in the field.
It’s a short review, but I couldn’t wait to show you this. For anyone serious about using a clip-on thermal like the Krypton 2, you owe it to yourself to try the Rusan adapter system. It makes thermal hunting feel effortless.
