Questions & Answers
I plan on using this with a holosun AEMS pro. Will I need a riser for that red dot to pair with this magnifier? If so, which one?

Yes, you will need a riser as this magnifier is designed to operate at 2.26" center. I have this magnifier paired with the AEMS on a unity fast mount.

I have a Unity Tactical FAST Micro Mount paired with a holosun HE515GT. Will this magnifier line up correctly? Can you answer this question?

conditional recommendation by Chip Johnson, Verified Owner, August 5, 2025
Friend has one and I was impressed with optics and how it center folds. Purchased for a new AR build and have high hopes. The “conditional” part of my recommendation comes from just unboxing the magnifier. A small spring on the arm holding the optic ...

Awesome Product. by CKH, Verified Owner, July 29, 2025
Product is great, easy to install and works great. For High-End AR Builds it's the perfect setup, and paired with Micro Prisms (Primary Arms), it's absolutely amazing, best part is obviously the flip-to-center, which is very nice and quick, compared ...

Excellent addition by Dom, Verified Owner, January 15, 2026
Anything Unity tactical is going to cost you but it's worth it. Great quality equipment all around. The glass is super clear, it's built with solid materials and the flip-to-center is badass. I especially like the 4x magnification

FAST FTC 4X by Alpha9, Verified Owner, December 7, 2025
Unity Tactical is of course a top notch, leading firearms gear maker. Hard to find a 4X Magnifier, and this is a really good one. Great glass and a 2.260 CL Height. Just be careful with whatever optic you mount in front of it...check the heights care...

Product Info for Unity Tactical FAST FTC 4X Magnifier

The FAST FTC 4X is the first integrated magnifier available on the market, bringing the magnifier up to a 2.26in optical centerline from the rail. Integrating the mount with the optic shaves weight, increases strength and ensures streamlined functionality with near-zero occlusion of the primary optic when stowed. The optical glass provides a clear and durable sighting solution while UNITY's FTC (flip-to-center) technology allows for easy stowage when not in use. Designed for use with a red dot mounted at the same height, the FAST FTC 4X provides ultimate picture clarity, utilizing the red dot in the primary optic as the aiming reticle. This allows the shooter to shift between non-magnified (stowed) and magnified aiming without re-zeroing the optic. The magnifier can be mounted on multiple weapons platforms behind a red dot sight or used as a hand-held monocular. It comes with an integrated FAST QD Lever that makes it even more low-profile.image
