MISO M1/M1A Lens Kit MISO Optics: Miniature Iron Sight Optics The MISO Sight: Includes MISO M1A Lens O Rings (2) Ridged Retainer Ring Insertion Tool Lens Remover Variable Focus Lens technology for true multifocal capabilities. Natural focusing from post to target and all those points in-between. NOT affected by slight changes of angle, perpendicular to the front post. This advantage allows the MISO lens to be easily adapted to the M1 Garand or M1A hooded rear sight. The MISO Lens is a single aspheric lens utilizing Variable Focus Lens Technology that creates a multifocal effect that brings near, intermediate and distance objects into focus at the same time. Simultaneous vision principles allow natural focusing at all distances from post to target and all those points in between. The lens optical center must be positioned directly in front of the pupil for best results at all distances. However, the image clarity through the lens is not affected by slight changes of angle, perpendicular to the front sight. This advantage allows the MISO Lens to be adapted to the M1A rear sight. High definition optics are incorporated for sharper image contrast and color and AR coated to maximize lens performance. The MISO lens is the best balance of powers to maximize a clear post and target aiming system without reducing the target image. For more information: www.ironsightoptics.com
