Aimpoint 3X-C Magnifier - 39mm FlipMount & TwistMount Base - The Aimpoint 3X-C Magnifier is a premium optic designed to increase capabilities for observation or target acquisition at longer distances. Whether it is paired with an Aimpoint red dot sight or used as a hand-held monocular, the 3X-C provides a crisp sight picture with a generous field of view. Utilizing the red dot in Aimpoint sights as the aiming reticle eliminates the need for re-zeroing when shifting between non-magnified and magnified aiming. This rugged magnifier module is fully waterproof and can withstand temperatures ranging from -31degF to +131degF. A shock absorbing protective rubber cover creates the ideal ergonomic grip when used as a hand-held device. Features include a 6-degree field of view (FOV) and a variable dioptric setting (-2 to +2), allowing the magnifier to be adjusted to the individual user's eye. The 3X-C Magnifier can be used with Aimpoint Micro T-2/H-2 and Comp series sights. Offered at an entry level price point, the 3X-C is the ideal solution to increase your capabilities without sacrificing the advantage of extremely quick target acquisition. 3X optical magnification Compatible with Aimpoint red dot sights for longer range aiming or observation Variable (-2 to + 2) dioptric setting Equipped with FlipMount(TM) and TwistMount(TM) base for easy picatinny rail attachment and removal Also serves as a handheld 3X monocular No re-zeroing needed when shifting between non-magnified and magnified aiming - utilizes the red dot in Aimpoint sights as the aiming reticle Ergonomic design for sure grip when used as a handheld observation tool Shockproof and Waterproof Legendary Aimpoint ruggedness at an entry level price point Screws and allen key included Field of view (FOV): 6deg Eye relief: 2.2in (56mm) Submersible to 2 Feet (.5 meters) Temperature range -31degF to +131degF (-35degC to +55degC) Weight 7.8 oz / 220g
