FTS

FTS (Flip-to-Side) is a type of mount designed for magnifiers — the zoom modules used behind red dot sights. It allows the shooter to quickly swing the magnifier to the side with a single motion, enabling instant switching between 1× magnification (red dot only) and a zoomed image (red dot + magnifier). FTS mounts are among the most common solutions on modern firearms and in airsoft — mainly due to their speed, reliability, and simple operation. FTS (Flip-to-Side) is therefore the most widely used magnifier mount — fast, robust, and intuitive. The magnifier flips to the side and instantly returns you to a 1× view. FTC (Flip-to-Center) is a more modern and streamlined alternative, where the magnifier folds downward into the mount without increasing the weapon’s width. Both systems have their advantages, but FTS is generally more practical for airsoft, CQB, and dynamic shooting.

Why is FTS important for magnifiers?

Instant switch between CQB and distance — one motion brings the magnifier in or out of view.
Speed — no need to remove or fold the magnifier downward.
Comfort — works intuitively even with gloves.
Full compatibility with red dots — especially Eotech, Aimpoint, Vector Optics, VictOptics, and others.

FTS mounts are most common with 3×–5× magnifiers, where switching between fast and more precise aiming is essential.

Difference between FTS and FTC mounts

FTS – Flip-to-Side
- The magnifier swings to the side (right or left side of the weapon).
- Fastest to operate.
- The most common and widely supported design.
- Simple and reliable mechanism.
FTC – Flip-to-Center
- The magnifier folds downward into the mount.
- Does not stick out to the side → slimmer profile, less snagging.
- More elegant and compact solution.
- Often more expensive than FTS.

When is FTS the better choice?

CQB and outdoor airsoft — fastest switching.
Weapons with accessories on the sides — no issue flipping the magnifier to the free side.
Traditional AR platforms.
When the shooter wants a simple, robust, and reliable mechanism.

When is FTC the better choice?

For users who want the slimmest possible weapon profile (nothing sticking out to the side).
For setups with many side-mounted accessories (lights, lasers, etc.).
For those who prefer minimal risk of snagging the mount on gear or obstacles.
