Zero Compromise
Every aspect of our manufacturing process is approached with the highest level of detail to both form and function. We believe a superior optic mount should perform impeccably while maintaining an equally impressive aesthetic profile. In an era where production is often outsourced, our lineage in advanced in-house manufacturing shapes our steadfast commitment to precision, reliability, and unparalleled quality. The MICRO-226™ represents this philosophy at its pinnacle—uncompromising performance with maximum modularity.
What is the difference between the MICRO-226™ and MICRO-193™?
The primary difference is optical centerline height. The MICRO-226™ provides a 2.26" height for aheads-up shooting posture, while the MICRO-193™ offers a 1.93" height. Both share identical construction quality, materials, and mounting technology. The MICRO-226™ is slightly more modular and accepts additional accessories like ourRMR-45™ andACRO-45™ offset mounts.
Which height should I choose - 1.93" or 2.26"?
The 2.26" height is ideal for shooters who prefer a heads-up shooting position, absolute co-witness with backup iron sights, or need additional clearance for night vision devices and magnifier combinations. Choose 1.93" if you prefer a more compact profile with lower third co-witness.
What does "FORTRESS™ accessory ready" mean?
This refers to our FORTRESS™ series accessories like ourDB-226™ Diving Board for additional rail space, and compatibility with offset mounts for backup optics or IR devices. The MICRO-226™ offers maximum modularity in our MICRO™ 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 MICRO-226™ is designed for any optic with the Aimpoint® MICRO™ 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 MICRO-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, absolute co-witness capability, night vision compatibility It's the preferred height for professional users who need maximum versatility.
