The absolute co-witness height makes it perfect for users who prefer a seamless sight picture between red dot and backup irons. Whether you re transitioning optics between rifles or fine-tuning your setup for close-quarters precision the RMR SIDELOK mount maximizes speed and confidence under pressure.
