Calculated Kinetics - SIG P211/P320 Romeo 1 Pro Optic Plates

The Calculated Kinetics optic plates are crafted from 7075 aluminum, which is known for its strength and durability. This material is often used in aerospace and military applications due to its high strength-to-weight ratio. The plates are also hard anodized, which enhances their resistance to wear and corrosion, ensuring longevity even under rigorous use.

These optic plates are designed to provide a lower 1/3rd co-witness with SIG #8 sights on P320s. This means that when you look through your optic, the iron sights will appear in the lower third of the sight picture. This setup is beneficial for quick target acquisition and allows for a backup sighting method in case the optic fails.

These optic plates are compatible with a variety of optics including the Holosun EPS, EPS Carry, 407k, and 507k. They also accommodate Trijicon RCR optics, although longer Capstan screws are required for these. This versatility makes them a great choice for users who may want to switch between different optics without needing new plates.

Yes, the Calculated Kinetics optic plates are designed to fit some older variants of the SIG P320. This makes them a flexible option for users with different versions of the P320, ensuring that they can upgrade their optics without compatibility issues. However, it is always recommended to verify specific model compatibility before purchasing.

Installing the Calculated Kinetics optic plates is straightforward, thanks to the included screws for different optic types. The plates come with 6-40 X 10.6MM screws for Holosun optics and 6-40 X 0.5" screws for Trijicon optics. For Trijicon RCR optics, longer Capstan screws are needed, which can be sourced with the optic. It's important to follow the installation instructions carefully to ensure a secure mount.

It is recommended to replace the screws on the Calculated Kinetics optic plates every 10,000 rounds. This helps prevent potential failures due to the cycling forces experienced during firing. Regular maintenance and inspection of the screws and plates can ensure optimal performance and safety.

7075 aluminum is highly valued for its exceptional strength and lightweight properties. This makes it an ideal material for optic plates, as it can withstand the stresses of repeated firing while adding minimal weight to the firearm. The hard anodized finish further enhances its durability, making it resistant to scratches and corrosion.

The Calculated Kinetics optic plates are engineered to withstand the cycling forces of various firearms, including those with significant recoil. The robust construction using 7075 aluminum and precise machining ensures that the plates remain secure under heavy use. However, it is crucial to ensure that the screws are properly tightened and inspected regularly to maintain their integrity.

Co-witnessing with OEM iron sights allows shooters to use both the optic and the iron sights simultaneously. This setup provides a backup sighting method in case the optic fails or the battery dies, ensuring continued accuracy and target acquisition. The lower 1/3rd co-witness offered by these plates is particularly useful for maintaining a clear sight picture.

Ensuring compatibility of optic plates with your firearm and chosen optic is crucial for a secure and functional setup. Mismatched components can lead to improper mounting, which may affect accuracy and reliability. Checking compatibility helps avoid potential issues and ensures that the optic functions as intended, providing the best possible shooting experience.
