Product Info for SIG SAUER Romeo4B 1X20 Low/Co .5MOA
Romeo4 is the ultimate red-dot sight when fast, accurate target acquisition is a must whether it's a moving target, dangerous game at full charge, or a fast breaking tactical situation at close quarters. Romeo4 sights are parallax-free so point-of-aim is point-of-impact and the red dot remains parallel to the bore of your firearm, no matter what your viewing angle is relative to the optical axis of the sight. Unlimited eye-relief allows you to acquire the aiming point and the target regardless of the position of your eye behind the sight. 5000+ hour battery life and the readily available CR2032 battery is side-loading, allowing for quick battery replacement. Dependable waterproof (IPX-7 rated for complete water immersion up to 1 atmosphere) and fog-proof performance.![]()
