Mounting & Compatibility Notes
-
Designed to be used with red dot sights, holographic sights and 1× prism optics mounted at the same height. No special footprint is required beyond a standard accessory rail spacing.
-
The flip-to-side mount lets you rapidly move the magnifier out of alignment when not needed.
-
Because different rifles and optics have slight height variations, you may want to confirm co-witness / sight height when pairing with a red dot (e.g., 1/3 vs absolute co-witness) — proper rail and riser heights can help align the magnifier pipe to your dot.

User Manual.
Q: What optics does this magnifier pair with?
A: It pairs with reflex red dots, holographic sights and 1× prism scopes that are mounted at the same optical height — letting you move between 1× and 3× instantly.
Q: How do I mount it?
A: The unit includes a Picatinny/Weaver flip-to-side mount that locks to your rifle’s rail; flip it into place for 3×, or out of the way for un-magnified vision
Q: Does it affect the sight picture sharpness?
A: It has tool-free diopter and azimuth adjustments so you can centre and focus the magnifier to match your red dot or prism output for clearer visuals.
Q: Can I use it with a holographic weapon sight?
A: Yes — it’s compatible with most holographic sights as long as the optic is at matching height on your rail.
Q: What’s the benefit of a flip-to-side mount?
A: Flip-to-side lets you maintain 1× reflex speed when magnification isn’t needed and then instantly snap into 3× for more precise shots — without changing optics. (General magnifier tip from red dot mounting practice.)
Q: What do co-witness / height relationships mean here?
A: Because red dot and magnifier optics must align in height, many shooters aim for co-witness heights (e.g., absolute co-witness ~36 mm or 1/3 co-witness ~40 mm) so both optics align well through the sight picture. Proper mount and rail choices help ensure this. (General magnifier alignment guidance.)
