SIG Sauer ROMEO5 Red Dot

My take on this unit is simple, easy use and long life of battery. Optic automatically turns off after minutes of no use (movement) and turns on when the firearm is picked up (movement). This works very well for home defense. Biggest downfall is riding in vehicles would turn optic on but battery life is supposibly 50,000 hours per battery. This optic is awesome for the price!

The Sig Sauer ROMEO 5 compact red dot sights provide civilians and armed professionals a robust 1x aiming solution for any situation. The sights are parallax-free so point-of-aim and point-of-impact remain the same. Unlimited eye-relief allows you to acquire the aiming point and the target regardless of the position of your eye behind the sight. The readily available CR2032 battery is side-loading, allowing for quick battery replacement (featuring 50,000 hours or more of life). Dependable waterproof (IPX-7 rated for complete water immersion up to 1 atmosphere) and fog-proof performance.
