FAQs

Please read our FAQs page to find out more.

What is the difference between the AEMS-226™ and AEMS-193™?

The primary difference is optical centerline height. The AEMS-226™ provides a 2.26" height for aheads-up shooting posture, while the AEMS-193™ offers a 1.93" height. Both share identical construction quality, materials, and mounting technology. The AEMS-226™ is modular and accepts additional accessories like our DB-193™ (Yes the AEMS-226™ is only comaptible with the DB-193™ not the DB-226™)

What does "FORTRESS™ accessory ready" mean?

This refers to our FORTRESS™ series accessories like our DB-193™ Diving Board for additional rail space, and compatibility with offset mounts for backup optics or IR devices. The AEMS-226™ offers maximum modularity in our AEMS™ footprint lineup.

What is the torque specification for installation?

The K-Clamp™ mounting system requires 25 in-lbs of torque. Over-torquing can damage the rail system or mount. Always use a quality torque wrench for installation.

Compatibility & Installation

Will this work with my specific optic?

The AEMS-226™ is designed for any optic with the Holosun® AEMS™ footprint pattern. Refer to our compatibility list above or contact our technical team for specific optic questions.

Can I use this mount with magnifiers?

Absolutely. Your magnifier mount will have to be a 2.26” compatible platform

Does this require any special tools for installation?

Installation requires only a T25 Torx bit (included) T10 Torx bit (included)  and a torque wrench capable of 25 in-lbs. All necessary hardware is included.

Will this co-witness with my iron sights?

No

Technical & Performance

How does the K-Clamp™ technology work?

Our patent-pending K-Clamp™ utilizes titanium components to distribute clamping force evenly across the Picatinny rail, preventing rail deformation while ensuring return-to-zero capability. The entire Kastle mount recesses down into the picatinny rail giving you a proprietary two point recoil lug system optimized at the front and rear of the mount compared to traditional mounting systems that only provide minimal recoil mitigation utilizing a single recoil lug at the center of the mounting interface or even worse interfaces that utilize the crossbolts as primary recoil lugs.

What's the difference between Type III anodizing and standard finishes?

Type III MIL SPEC hardcoat anodizing provides superior corrosion resistance and surface hardness compared to standard Type II finishes, ensuring long-term durability in harsh environments.

Can this mount handle full-auto fire?

Absolutely. The MICRO-226™ has been tested extensively with full-automatic select fire weapons systems and maintains zero under extreme conditions.

What's the expected lifespan of this mount?

With proper installation and normal use, the AEMS-226™ is designed for indefinite service life. That's why we back it with our lifetime warranty.

Why choose the 2.26" height over other options?

The 2.26" height provides the optimal balance for heads-up shooting posture, fast target acquisition and night vision compatibility.

Color & Customization

Which color should I choose?
  • Black - You should know this one.
  • Flat Dark Earth - Traditional deep & rich FDE color. Pairs great with all shades of FDE.
  • Desert Sand - On the lighter side of the "Tanodize" spectrum and pairs well with less saturated shades of tan or FDE.
  • Clear - This anodize produces a champagne grey finish that shifts with the light. Pairs great with all clear ano and Q™ products.
  • OD Green - No, we didn't forget about this classic. Pairs well with anything olive drab or ranger green. Also a good match with Noveske™ bazooka green.

Pro Tip: Try mix-matching colors for a unique look.

Disclaimer: Anodize processing varies slightly in color by batch. Anodize may look different than what is pictured.

Can I have this mount custom Cerakoted?

Yes, any color can be Cerakored but ordering in "Clear" finish is preferred for custom Cerakote applications.
