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 three 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. Includes a M1913 Picatinny low mount riser and a co-witness 1.41 riser mount.
