ButtonBlocker - Sig Sauer Romeo4TPro

We really like everything about the Romeo 4T Pro. However, we noticed one design issue that stood out during real-world use. The night vision button is significantly larger than the brightness buttons, making it easy to accidentally engage NV mode. Even worse, when exiting NV mode, the optic defaults to its highest brightness setting. In critical moments, that’s far from ideal. So we set out to fix it.The result is the ButtonBlocker. This simple, snap-fit shield shrouds the button assembly, making it much harder to unintentionally activate the brightness controls—or the oversized NV button—while still maintaining full functionality when you actually need it. A small solution to a frustrating problem, designed the way it should have been from the start.
