HS510C FDE Red vs. HS510C FDE Green — Which Is Right for You?

Both are identical in features and FDE finish. The FDE Red ($365.99) uses a red dot — preferred by many shooters in low-light and indoor conditions. The FDE Green ($365.99–$379.99) uses a 540nm green dot — more visible in bright outdoor daylight. Choose based on your primary shooting environment.

Who Is the HS510C FDE Red For?

The HS510C FDE Red is the top choice for AR-15 and MSR shooters building a tan or FDE rifle who want a feature-packed open reflex sight with a red dot. It's ideal for FDE build enthusiasts who want a cohesive aesthetic, hunters and 3-gun competitors who prefer red dot visibility, and anyone upgrading from a black HS510C to match their FDE build. If you're asking "best FDE red dot for AR-15?" or "Holosun HS510C FDE red vs green — which should I buy?" — the FDE Red is the answer for red dot preference.
