ADVANCED TECHNOLOGY: The Holosun HS510C New advanced technology LED allows up to 50,000 hours of operation on one CR2032 battery. 
PROTECTIVE TITANIUM ALLOY HOOD: The Holosun HS510C Circle Dot Scope with 3 Reticle Options is waterproof down to 1m and durable enough for even the heaviest calibers. 
EASY USE: The reticle can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary.
