The new LITEWAVE sight design from HIVIZ features an innovative, diagonal-wave design that increases durability to the protective exoskeleton and allows for more exposed surface area for the LITEPIPE to gather light from all angles, for the brightest sight available. RugerA(R) MKII/III LITEWAVE front sight fits MK II/III(TM) heavy barrel guns including 22/45(TM) with adjustable rear sight only. Does not fit 22/45 Lite model. Also Fits Browning Buckmark pistols (except Challenge, 5.5 Target, and 5.5 Field). Will fit RugerA(R) Single SixA(R) revolvers with adjustable rear sights. Includes interchangeable LitePipes in red, green, and white. Mfg: Hiviz
