The Sig Sauer JULIET3 3x24mm Magnifier features a flip-up design with a reliable PowerCam 90° Mount, which makes transitioning from close quarters to intermediate ranged targets fast and easy by quickly flipping up when you’re engaging with targets at extended ranges and flipping down and out of the way when you need true 1x magnification for close quarter targets. The CNC-machined aluminum housing offers lasting durability and shockproof performance, while O-ring seals deliver an IPX8 submersible waterproof rating for maximum versatility. The dialect-coated prism delivers optimal clarity. Plus, the front and rear thread-in lens protectors offer superior scratch, drop, and water protection when working in challenging environments. Backed by Sig’s lifetime Infinite Guarantee™. Includes 1.41″, 1.53″, and 1.63″ spacers for customizable height.
