Arisaka Defense - Eotech EXPS Mount Mk2 1.93 FDE Cerakote

The Arisaka Defense Eotech EXPS Mount Mk2 offers several advantages for users of the Eotech EXPS3 and EXPS2 holographic sights. By replacing the OEM mount, it eliminates the need for a separate riser, providing a 1.93-inch optic centerline height that enhances compatibility with magnifiers. This streamlined setup is particularly beneficial for tactical scenarios where quick target acquisition is crucial. Additionally, the mount retains the quick-detach (QD) feature, allowing for rapid attachment and detachment without compromising stability or accuracy.

The 1.93-inch optic centerline height of the Arisaka Defense Eotech EXPS Mount Mk2 is designed to improve shooting performance by providing a more natural shooting position. This height allows for a more heads-up shooting posture, which can enhance situational awareness and reduce neck strain during prolonged use. It is particularly advantageous when wearing tactical gear, such as helmets or night vision equipment, as it minimizes the need to adjust your head position to align with the sight.

The Arisaka Defense Eotech EXPS Mount Mk2 is specifically designed for compatibility with the Eotech EXPS3 and EXPS2 models. It supports all reticle variants of these models, including the EXPS3-0, EXPS3-1, EXPS3-2, and EXPS3-DCR. However, it is not compatible with other Eotech models such as the EXPS3 HD, XPS3, XPS2, 518, 558, 552, or 512. Users should verify their optic model before purchasing to ensure compatibility.

The Arisaka Defense Eotech EXPS Mount Mk2 is constructed from high-quality 7075-T651 aluminum. This material is known for its strength and durability, making it an excellent choice for tactical applications. The mount is finished with a MIL-A-8625 Type III hard coat black anodizing and an optional FDE Cerakote layer. This combination not only enhances the mount's resistance to wear and corrosion but also provides a tactical aesthetic that matches other equipment.

The ADM QD lever included with the Arisaka Defense Eotech EXPS Mount Mk2 enhances its functionality by providing a quick-detach mechanism. This feature allows users to rapidly attach or detach the optic from their firearm without the need for tools. It is particularly useful in situations where equipment needs to be reconfigured quickly, such as transitioning between different operational environments or when packing gear for transport. The QD lever ensures that the mount remains securely attached during use, maintaining zero and reliability.

The Arisaka Defense Eotech EXPS Mount Mk2 weighs 2.6 ounces, which is a slight increase of 0.6 ounces over the OEM mount. While this adds a bit of weight to the overall setup, the increase is minimal and generally does not impact the balance or handling of the firearm. The tradeoff for this slight weight increase is the enhanced durability and functionality provided by the mount's robust construction and quick-detach capability.

The Arisaka Defense Eotech EXPS Mount Mk2 comes with all necessary installation hardware to ensure a secure attachment. This includes two 10-32x5/16" Phillips head undercut screws and two 6-32x5/16" Torx flat head screws. These components are designed to provide a stable and reliable connection between the optic and the mount, ensuring that the sight remains firmly in place even under recoil.

The FDE Cerakote finish on the Arisaka Defense Eotech EXPS Mount Mk2 provides both aesthetic and functional benefits. Cerakote is a ceramic-based coating known for its excellent durability and resistance to abrasion, corrosion, and chemicals. This finish not only enhances the mount's longevity but also provides a tactical, non-reflective surface that reduces the risk of glare and detection in operational environments.

When installing the Arisaka Defense Eotech EXPS Mount Mk2, it is important to adhere to the recommended torque values to ensure a secure fit. The recommended torque for attaching the optic to the mount is 25 inch-pounds (2.8 Nm), while the shroud should be tightened to 12 inch-pounds (1.35 Nm). Proper torque application helps prevent damage to the mount and optic while maintaining optimal performance and reliability.

While the Arisaka Defense Eotech EXPS Mount Mk2 offers significant benefits, it does have some limitations. It is not compatible with certain Eotech models such as the EXPS3 HD, XPS3, XPS2, 518, 558, 552, or 512. Additionally, the slight weight increase over the OEM mount may be a consideration for users prioritizing ultra-lightweight setups. Despite these limitations, the mount's robust construction and enhanced functionality make it a valuable addition for compatible optics.
