Calculated Kinetics - Glock 43x/48 MOS Adapter Plate for Holosun

The primary function of the Calculated Kinetics Glock 43x/48 MOS Adapter Plate is to securely mount Holosun optics onto Glock 43x and 48 MOS models. This adapter plate is specifically designed to fit Holosun models such as the 407K, 507K, EPS Carry, and EPS. By providing a stable platform, it ensures that your optic remains securely attached, maintaining accuracy and reliability during use. The adapter is crafted from durable 6061 aluminum and features a hard anodized black finish, contributing to its longevity and resilience in various conditions.

The adapter plate is engineered to position the optic at a height that allows for a lower 1/3rd co-witness with Ameriglo GL-453 sights. This means that when you look through your optic, the iron sights will appear in the lower third of the optic window, allowing for quick transition between the optic and iron sights. This setup is beneficial in tactical situations where redundancy and quick sight picture acquisition are crucial.

The adapter plate is constructed from 6061 aluminum, a material known for its strength and lightweight properties. The use of 6061 aluminum ensures that the adapter plate can withstand the rigors of repeated use and environmental stress without adding significant weight to your firearm setup. Additionally, the hard anodized black finish enhances its durability by providing resistance to corrosion and wear, ensuring a long service life even in challenging conditions.

The adapter plate comes complete with all necessary hardware, Vibratite, and installation instructions. The inclusion of these components ensures that users have everything needed for a secure and proper installation. Vibratite is particularly important as it helps prevent screws from loosening under recoil, maintaining the integrity of the mount over time. Following the installation instructions carefully will help ensure that the adapter plate is mounted correctly for optimal performance.

Replacing the screws every 10,000 rounds is recommended to maintain the structural integrity of the mount. Over time, the repeated shock and vibration from firing can cause screws to wear or loosen, potentially compromising the security of the optic. By proactively replacing the screws, you minimize the risk of failure, ensuring that your optic remains firmly attached and your firearm performs reliably.

The adapter plate is compatible with several Holosun models, including the 407K, 507K, EPS Carry, and EPS. This compatibility ensures that users can choose from a range of optics to suit their specific needs and preferences. Each model offers different features, such as reticle options and battery life, allowing users to customize their setup for various shooting scenarios.

The adapter plate includes specific screws tailored for different Holosun models. For the EPS, EPS Carry, and EPS Core models, M4 X 11MM screws are provided, while the 407K and 507K models require M4 X 12MM screws. These precise measurements ensure a secure fit, preventing any movement or misalignment of the optic during use.

The hard anodized finish on the adapter plate provides several benefits, including enhanced durability and corrosion resistance. This finish creates a protective layer that shields the aluminum from environmental factors such as moisture and abrasion, which can degrade materials over time. As a result, the adapter plate maintains its structural integrity and appearance, even with extensive use in harsh conditions.

Manufacturing the adapter plate in the USA ensures high-quality standards and supports local industry. Products made domestically are often subject to stringent quality control measures, resulting in reliable and durable items. Additionally, purchasing American-made products supports the local economy and can provide quicker customer service and support due to geographical proximity.

Using a lower 1/3rd co-witness setup offers quick transition between optic and iron sights, but it also has tradeoffs. While this configuration allows for a clear view through the optic without obstruction from the iron sights, it requires the shooter to slightly adjust their line of sight to use the irons. This can be a minor inconvenience in rapid shooting scenarios. However, the benefit of having backup sights readily available often outweighs this drawback, especially in tactical or self-defense situations.
