A magnifier sits behind your red dot or holographic sight and adds 2x to 6x when you need it. Flip it to the side and you are back to a fast 1x dot. It is the simplest way to give a red dot rifle more reach without changing your zero.
What you will find
- SIG SAUER JULIET3 and JULIET3-Micro, including the popular ROMEO5 + JULIET3-Micro combo kits
- EOTECH G33, G43 and G45 magnifiers with or without STS mounts
- Vortex VMX-3T, Holosun HM3X, Primary Arms SLx and GLx, Bushnell and Sightmark T-3
- Monstrum Ghost G3 bundles and the Monstrum 2X forward magnifier for prism scopes and LPVOs
How to choose
Match the magnifier's centerline height to your sight (absolute or lower 1/3 co-witness), and check that the flip mount clears your charging handle and rail space. A complete combo kit removes the guesswork.

Frequently asked questions
Do I need to re-zero my red dot after adding a magnifier?
No. A magnifier does not change the point of aim of the red dot; you only need to set the magnifier's own position on the rail.
3x or 5x magnifier?
3x is lighter, shorter and has a wider field of view. 5x helps identification at longer range but is bigger and more sensitive to head position.
Will any magnifier work with my red dot?
Most work with tube and holographic sights if the centerline heights match. Check the mount height listed for both the sight and the magnifier.
