Pulsar PSP-42B Ring Adaptor
The Pulsar PSP-42B Ring Adaptor is a precision mounting adapter designed to let you fit Pulsar Krypton and Proton thermal clip-ons onto daytime rifle scopes with 40–42mm objective lenses. It uses a clever insert system and a quick-release bayonet lock, so once it’s set up properly it gives you a rock-solid, repeatable alignment without fiddling every time you mount the thermal unit. Built for stability, speed, and optical alignment, it basically turns your day scope into a reliable thermal-ready platform without permanently modifying anything.

1. What is the PSP-42B used for?
It’s used to mount Pulsar Krypton and Proton thermal imaging attachments onto compatible daytime rifle scopes.
2. What size scopes does it fit?
It’s designed for scopes with a 40–42mm objective lens diameter, using interchangeable inserts for exact fitting.
3. Does it work with all rifle scopes?
It works with most daytime optical scopes and tube-style scopes (including 30mm tube designs), as long as the objective diameter matches the adapter range.
4. What makes it different from a basic ring mount?
It uses a bayonet quick-release system and a precise alignment mechanism so the thermal image stays correctly centred in the scope view.
5. Is installation permanent?
No, it’s fully removable, so you can switch the thermal attachment between scopes if needed.
6. Does it affect zeroing or alignment?
It’s designed to maintain repeatable positioning, helping keep alignment consistent when reattaching the clip-on.
7. What comes in the box?
Typically the ring adapter body, insert rings, Allen keys, double-sided tape, and a manual.
8. How is it mounted to the scope?
It clamps onto the objective housing using an insert matched to the exact diameter, then locks in place with a lever system.
9. Why are inserts needed?
They allow one adapter model to fit multiple slightly different scope diameters while keeping a tight, secure fit.
10. What’s the main benefit in the field?
It lets you quickly attach or remove a thermal clip-on while keeping consistent optical alignment for reliable use in changing conditions.
