    • You can likely install a Holosun 507K on a Mossberg MC1SC as it shares the same footprint as the Shield RMSC. However, the rear studs on the slide might not align perfectly with the rear divots on the 507K. This could affect the sight’s accuracy, making it shoot low. So, while it fits, it may not be a seamless installation.
