Two Brothers Military Engineering 2BME Mounting Plate 2BME019 Sig Sauer Legion / M18 / M19 (P320 with removable rear sight) for Aimpoint Acro + rear sight

The 2BME019 mounting plate allows mounting the Aimpoint Acro red dot sight on Sig Sauer Legion / M18 / M19 pistols and the P320 with a removable rear sight.

2BME red dot mounting plates 

The bases are designed and manufactured by the Polish company TBME (Two Brothers Military Engineering), which uses high-class DMG-Mori CNC machines for the production of its components. TBME plates are dedicated to pistols that are factory-prepared (or adapted by a gunsmith) for mounting red dot sights directly on the slide.

The bases are made of 7075-T6 aircraft-grade aluminium, which makes them extremely durable and very lightweight (depending on the model, approx. 8 g). The plate is finished with hard anodizing according to military specifications (MIL-SPEC), increasing surface resistance to scratches and wear. Anodizing is a process that hardens the aluminium surface and protects it from oxidation. TBME mounting plates stand out not only for their durable finish and perfect weapon fit but also for allowing exceptionally low installation of the red dot sight. Thanks to the use of measuring probes, the plates are precisely dimensioned and matched to the factory milling of the firearm. To ensure stable and reliable mounting, the plate uses a system of steel interchangeable "Quad Lock" inserts, which allows the use of screws with strong, multi-thread connections (excluding models mounted on the so-called dovetail). The set includes all components necessary for mounting the optic on the firearm: the strongest 4 A4-class stainless steel Torx screws on the market, a tube of threadlocker, and installation instructions.

For installing the plate and the optic, it is recommended to use a medium-strength threadlocker (included) and a torque wrench set to 1.2 Nm. Before final installation, it is advisable to fit the complete plate (with threaded inserts) and the optic without threadlocker. This verification ensures that the plate is properly matched to both the optic and the firearm.

The TBME 2BME019 plate is designed for mounting the Aimpoint Acro red dot sight on Sig Sauer Legion / M18 / M19 pistols and the P320 with a removable rear sight.
