The Glock MOS Optic Plate can be made by many manufacturers, but only Calculated Kinetics has the DOGTAG. The DOGTAG is an anodized, multi-faceted mount plate that offers protection and helps reduce carbon buildup on the glass by using a gas deflection table on the front. This feature is especially noticeable when running suppressed. Their DOGTAG also minimizes the space between the optic and the slide, securing the optic to prevent any movement and eliminating the risk of the red dot shifting off zero. Additionally, the deflection table doubles as an action point for single-hand operation, such as in case of an injury, allowing the user to perform the action without damaging the optic.Features :Fits GLOCK M.O.S.
