Arisaka Defense - Eotech EXPS Mount Mk2 1.93" - Black

The Arisaka Eotech EXPS Mount Mk2 provides a significant advantage by eliminating the need for a riser, thanks to its 1.93-inch centerline optic height. This design choice not only reduces the overall weight of your setup but also maintains a streamlined profile. Additionally, the mount retains the quick-detach (QD) feature of the original equipment manufacturer (OEM) mount, allowing for rapid attachment and detachment without compromising stability. The use of 7075-T651 aluminum ensures durability while the MIL-A-8625 Type III hard coat anodizing provides a robust finish.

The Arisaka Mk2 mount weighs 2.6 ounces, which is a 0.6-ounce increase over the OEM mount. While this might seem like a slight increase, the trade-off is a more robust and versatile mounting solution that negates the need for additional risers. This weight consideration is important for those looking to maintain a lightweight setup, especially in scenarios where every ounce counts, such as long-duration field operations or tactical maneuvers where agility is crucial.

The Arisaka Eotech EXPS Mount Mk2 is specifically designed to be compatible with all reticle variants of the EXPS3 and EXPS2 models. This includes models such as the EXPS3-0, EXPS3-1, EXPS3-2, and EXPS3-DCR. However, it is not compatible with other models like the EXPS3 HD, XPS3, XPS2, 518, 558, 552, or 512. It's crucial to verify your optic model before purchasing to ensure compatibility and optimal performance.

The Arisaka Mk2 mount is constructed from 7075-T651 aluminum, known for its high strength and durability. This material choice ensures that the mount can withstand the rigors of tactical use and harsh environmental conditions. The mount is finished with a MIL-A-8625 Type III hard coat black anodizing, providing additional protection against wear and corrosion. For those seeking a different aesthetic, an optional FDE Cerakote finish is available.

The quick-detach (QD) feature of the Arisaka Mk2 mount is facilitated by the inclusion of an ADM QD lever. This lever allows for rapid attachment and detachment of the mount without the need for tools, making it ideal for situations where quick adaptability is required. Whether transitioning between different optics or removing the sight for transport, the QD feature ensures that you can do so efficiently while maintaining a secure attachment when in use.

When installing the Arisaka Mk2 mount, it is important to adhere to the recommended torque values to ensure a secure fit. The optic to mount should be torqued to 25 inch pounds (2.8 Nm), while the shroud should be torqued to 12 inch pounds (1.35 Nm). Proper torque application prevents damage to the mount and ensures that the optic remains securely in place during use. Using a torque wrench is advisable to achieve these precise values.

Yes, you can use the original screws from your Eotech sight with the Arisaka Mk2 mount. The mount comes with spare screws, but reusing the original screws is recommended for optimal fit and security. This compatibility ensures that you can seamlessly integrate the mount into your existing setup without the need for additional hardware, simplifying the installation process.

The 1.93-inch optic height of the Arisaka Mk2 mount offers several tactical advantages. This height allows for a more natural shooting posture, reducing neck strain and improving target acquisition speed, especially when using night vision devices or gas masks. It also enhances situational awareness by allowing for a heads-up shooting stance, which is beneficial in dynamic environments where quick target transitions are necessary.

The Arisaka Mk2 mount is well-suited for use in harsh environmental conditions due to its robust construction and protective finishes. Made from 7075-T651 aluminum, the mount is both lightweight and strong, capable of withstanding the demands of rugged use. The MIL-A-8625 Type III hard coat anodizing further enhances its resistance to corrosion and wear, ensuring reliability in challenging environments, whether in desert, jungle, or arctic conditions.

The Arisaka Mk2 mount is protected by U.S. Patent No(s). US7823316B2 and other pending patents. This patent protection underscores the unique design and engineering innovations that the mount incorporates. These protections ensure that the specific features and benefits of the mount are exclusive to Arisaka, providing users with a product that is both innovative and legally safeguarded against imitation.
