Pulsar Proton FXQ30 Thermal Clip-On
The Pulsar Proton FXQ30 is a compact thermal clip-on: it attaches in front of your existing day scope so you gain night capability without re-zeroing. Built around a 384x288 (XQ) sensor in a small body, it suits hunters who want a light, affordable front attachment for shorter-range work rather than a full dedicated thermal scope.
Pros
- Compact, lightweight front attachment that is easy to carry
- Mounts ahead of your day scope - add thermal with no re-zero
- 384x288 sensor suited to closer and moderate hunting ranges
- Keeps your existing day rifle usable day and night
Cons
- 384x288 sensor shows less detail at distance than a 640x480 clip-on
- Shorter detection range than the Krypton 2
- Needs a correctly sized adapter for your day scope's objective
- ITAR export-controlled
How a clip-on differs from a dedicated scope
The core idea behind the Proton is the clip-on form factor. Rather than replacing your optic like a dedicated thermal riflescope, it mounts to the objective of your day scope through an adapter. Your day scope keeps its own zero, you add thermal for the night, and you pull the attachment off for daytime shooting. That gives you one rifle and one zero used around the clock. The compromise is that the resulting image comes from pairing two devices, so adapter fit and the quality of your day scope both shape the final picture. See the category on our thermal clip-ons page.
What the Proton FXQ30 is and who it suits
The FXQ designation points to a 384x288-class thermal sensor, and the 30 reflects a compact objective. That combination keeps the Proton small and light, which is its main appeal: it is an easy-carrying front attachment for hunters who prioritize portability and value over maximum reach. A 384x288 sensor is well matched to closer and moderate distances - think field edges and stand hunting for hogs and predators - where fine long-range detail matters less. If you mostly scan and shoot inside typical hunting ranges and want to keep your current rifle setup, the Proton covers that cleanly.
Where the Proton sits and who should look elsewhere
Within Pulsar's clip-on family the Proton is the compact, lower-resolution option. Step up to the Krypton 2 when you want a 640x480 sensor, a faster lens, and much longer detection for open-country reach - at higher cost and weight. The older Core attachments are an alternative to research on the used market. If you would rather not stack a clip-on on an existing scope at all, a dedicated Talion scope is the value route to purpose-built thermal. Compare options on the best thermal clip-ons shortlist.
Frequently Asked Questions
Does the Proton need re-zeroing?
No. It clips in front of your day scope, which keeps its own zero. You attach the Proton for night hunting and remove it for daytime without changing your zero - the main benefit of a clip-on over a dedicated scope.
Is the Proton a scope or an attachment?
It is a front thermal attachment, not a stand-alone scope. It works with your existing day optic. If you want a dedicated thermal scope you mount and zero on its own, look at the Talion instead.
How does the Proton compare to the Krypton 2?
The Proton is the compact, 384x288 option for shorter ranges and easy carry. The Krypton 2 uses a higher-resolution 640x480 sensor and a faster lens for far greater reach, at more weight and cost.
What adapter does the Proton need?
You need an adapter matched to your day scope's objective-bell diameter so the thermal image lines up concentrically with your optic. Confirm the correct adapter for your scope before buying.
