Calculated Kinetics has engineered a robust solution for shooters who want to use RMR-pattern optics on SIG pistols originally cut for the Romeo 1 Pro. This adapter plate bridges that gap with precision and durability.
The adapter is straightforward to install on any SIG Romeo 1 Pro cut featuring the required two channels in the milled space. Vibratite threadlocker is included to ensure your optic stays put through thousands of rounds.
If you've invested in quality RMR optics and want to use them across your SIG platform, this adapter eliminates the need for multiple optics or expensive re-cutting. It's a practical solution for serious shooters who demand flexibility and reliability.
