Calculated Kinetics - SIG P211/P320 Optic Plates for RMR Footprints

The Calculated Kinetics SIG P211/P320 Optic Plates are crafted from 7075 aluminum, a material known for its strength and durability. This high-grade aluminum is hard anodized, which enhances its resistance to wear and corrosion. The choice of 7075 aluminum ensures that the optic plates can withstand the rigors of regular use, making them a reliable option for both tactical and recreational shooting scenarios. The hard anodized finish not only adds to the durability but also provides a sleek, professional appearance.

These optic plates are specifically designed to fit SIG P211 and some older variants of the P320, allowing users to mount optics with RMR footprints securely. By ensuring a secure fit, they enhance the accuracy and versatility of these pistols, making them suitable for a variety of shooting applications. The plates also allow for a lower 1/3rd co-witness with SIG #8 sights on the P320, which is beneficial for maintaining sight alignment if the optic fails or is removed.

The co-witness feature allows shooters to align their iron sights with the mounted optic, providing a backup aiming method. For the SIG P320, these plates enable a lower 1/3rd co-witness with SIG #8 sights, which means the iron sights are visible in the lower third of the optic's window. This setup is advantageous in tactical situations where quick transitions between optic and iron sights are necessary, such as when the optic's battery fails or in close-quarters combat.

To ensure the longevity and reliability of the optic plates, it is recommended to replace the screws every 10,000 rounds. This practice minimizes the risk of screw failure, which can compromise the stability of the mounted optic. Regular inspection of the screws and the plate's condition is advised, especially after extensive shooting sessions. Keeping the plates clean and free from debris will also help maintain their performance.

These optic plates are compatible with all optics that have RMR footprints, providing flexibility in optic selection. Whether you prefer Trijicon, Holosun, or other brands, these plates offer a secure mounting solution. This compatibility allows users to choose optics based on their specific needs, such as low-light performance or reticle options, without worrying about fitment issues.

The optic plates come with screws tailored for different optics, simplifying the installation process. Specifically, the package includes 6-40 X 10.6MM screws for Holosun and Osight optics, and 6-40 X 0.5" screws for Trijicon optics. This ensures that users have the correct hardware for a secure and reliable installation, reducing the likelihood of installation errors or optic movement during use.

The hard anodized finish on the optic plates provides enhanced resistance to wear and corrosion. This is particularly beneficial in harsh environments where moisture and debris can affect equipment. The finish not only protects the aluminum from physical damage but also maintains its appearance over time, ensuring that the plates remain functional and visually appealing even after extensive use.

The compatibility with the Holosun 509T DOGTAG allows for a lower 1/8th co-witness with SIG #8 sights. This setup is ideal for users who prefer a more streamlined sight picture with minimal obstruction from the iron sights. It provides a clear view through the optic while still offering the option to use iron sights as a backup, enhancing versatility in various shooting scenarios.

When selecting optics for these plates, users should consider the intended use, such as tactical, competitive, or recreational shooting. Factors such as reticle type, battery life, and environmental conditions should influence the choice of optic. Additionally, ensuring that the optic's footprint is compatible with the RMR standard is crucial for a secure fit. Users should also consider the co-witness capability and how it aligns with their shooting style.

A secure fit for optics on pistols is essential to maintain accuracy and reliability during shooting. An improperly mounted optic can shift under recoil, leading to inconsistent shot placement. The Calculated Kinetics optic plates are designed to provide a stable platform for optics, ensuring that they remain in place even under the stress of repeated firing. This stability is crucial for tactical applications where precision and dependability are paramount.
