Sig Sauer ROMEO5/JULIET3 1x20 mm Magnifier Combo 2MOA ROMEO5 compact red dot sights provide civilians and armed professionals a robust 1x aiming solution for any situation. Ultra-low parallax 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. The readily available CR2032 battery is side-loading, allowing for quick battery replacement (featuring 40,000+ hours or more of life). Dependable waterproof (IPX-7 rated for complete water immersion up to 1 atmosphere) and fog-proof performance. The JULIET3 3x Magnifier is designed to work as a stand-alone magnification solution or in conjunction with reflex optics. This family of magnifiers is an excellent choice for transitioning from close quarters to intermediate ranged targets. In conjunction with a reflex optic, the JULIET3 can be adjusted for height through the use of spacers. It has a PowerCam 90° Mount so it can be quickly flipped to the side for more immediate, close quarters scenarios or deployed rapidly to bring targets four times closer. Its quick release mount comes with built-in recoil lugs for repeatable zero. The JULIET3 has a front and rear thread-in lens protector to keep it secure from the elements.
