Red dot adapter plates for Sig Sauer P320 optic-ready models. Crafted from aircraft-grade aluminum, these optic plates from 2BME are ultra-lightweight, minimizing impact on firearm cycling for enhanced reliability. Featuring steel "Quad Lock" threaded inserts for secure, low-profile collimator mounting, plates are coated with a Mil-Spec hard-anodized finish for superior scratch and corrosion resistance.

Precision-manufactured for a perfect fit, sets include high-strength stainless steel Torx screws, thread-lock adhesive, and installation instructions. Replacement parts are available (2BME Service Pack).

For optimal results, tighten screws to 1.5 Nm and consult a gunsmith if needed.

The plate is intended for mounting the red dot collimators given in the Compatibility section. Due to attempts by manufacturers to standardize collimator mounts, it may be possible to mount other collimators with the same footprint (pin and hole spacing). However, this could lead to installation issues due to the differing shapes of housings across various models and manufacturers. If the collimator requires countersunk screws for mounting, attach the collimator to the plate without the slide and choose the appropriate screw length.
