Red Dot Magnifiers & Flip-to-Side Magnifier Mounts 

Explore red dot magnifiers, holographic sight magnifiers and flip-to-side magnifier mounts for compatible optics setups. This collection includes Holosun HM3X, HM3XT and HM6X magnifiers, the EOTECH G33 STS 3x magnifier and the Unity Tactical FAST FTC OMNI magnifier mount.

A magnifier sits behind a compatible red dot sight, reflex sight or holographic optic to add fixed optical magnification while still allowing fast return to an unmagnified 1× view. Before choosing a magnifier, confirm magnification level, mount height, eye relief, field of view, optical centreline, co-witness compatibility, rail interface and available space behind the primary optic.

Choose the Right Red Dot Magnifier

3x Red Dot Magnifiers

3x magnifiers are the most common option for users who want extra detail without heavily changing the feel of a 1× red dot setup. The Holosun HM3X is an aluminium-bodied 3x magnifier with an ambidextrous flip-to-side QD Picatinny mount, absolute and lower 1/3 spacer compatibility, 70 mm eye relief, 7-degree field of view and IP67 water resistance.

The Holosun HM3XT is a compact titanium-bodied 3x magnifier with a quick-release flip-to-side mount, absolute and lower 1/3 co-witness compatibility, 70 mm eye relief and IP67 water resistance.

EOTECH G33 Magnifier

The EOTECH G33 STS Magnifier is a 3x magnifier designed for EOTECH HWS setups and supplied with a Switch-to-Side mounting system. It offers 2.2 inches of eye relief, a 7.3-degree field of view, 10 m water resistance and compatibility with 1-inch Weaver or MIL-STD-1913 rails.

Use the G33 when pairing with EOTECH EXPS or compatible holographic optics, especially where a proven 3x magnifier with tool-free adjustment and STS mounting is preferred.

6x Magnifiers

The Holosun HM6X provides 6x magnification for users who want more detail than a 3x magnifier can provide. It includes an ambidextrous QD flip mount, spacer for absolute and lower 1/3 height optics, adjustable diopter, 65 mm eye relief, 3.7-degree field of view and a 7075 aluminium housing.

A 6x magnifier provides more optical reach, but it can also make eye position, field of view and stability more demanding. Compare 3x and 6x magnifiers according to the intended optic, mount height, distance, viewing position and comfort behind the optic.

Flip-to-Side and Flip-to-Centre Magnifier Mounts

The Unity Tactical FAST FTC OMNI is a magnifier mount rather than a magnifier. It raises compatible magnifiers to a 2.26-inch optical centreline and uses a flip-to-centre mechanism to stow the magnifier below the optical sight plane instead of pushing it outward to the side.

This mount should be selected only after confirming magnifier compatibility, optic height, rail space and preferred stowed position. It is designed for compatible EOTECH, Aimpoint, Holosun, SIG Sauer, Trijicon and Vortex magnifiers, but the exact model and footprint should be verified before ordering.

Magnifier Compatibility Checklist

Before selecting a red dot magnifier or mount, confirm:

• Magnification level: 3x or 6x
• Primary optic type: red dot, reflex sight or holographic sight
• Mount height: absolute, lower 1/3 or 2.26-inch FAST height
• Rail interface: Picatinny / MIL-STD-1913 or Weaver
• Eye relief and usable eye box
• Field of view
• Exit pupil
• Diopter adjustment
• Windage and elevation alignment adjustment
• Flip-to-side or flip-to-centre operation
• Included spacer, riser, QD lever or STS mount
• Clearance with backup sights, switches and rear accessories

Magnifiers and Night Vision

Magnifiers are primarily used behind day optics. For passive night vision aiming, a night-vision-compatible red dot or holographic sight is usually more important than adding magnification. Users building night vision setups should compare optic brightness settings, mount height, reticle bloom, helmet-mounted device position and magnifier clearance before relying on a magnified setup.

Browse compatible red dot and holographic sights, scopes and optic mounts, laser aiming modules, tactical lights and IR illuminators, remote pressure switches and night vision goggles.

Complete Your Optics Setup

Pair a magnifier with a compatible Holosun or EOTECH red dot / holographic sight, a correct-height optic mount, rail space, lens protection and any required risers or spacers. Read our night vision and optics terminology guide and helmet-mounted night vision setup guide for wider setup planning.
