Just released the new MFI Low Profile Scope mount for the GSG-5 and the Umarex HK MP5 models offers the lowest profile of any HK scope mount on the planet with the best fit as these were made exclusively for the GSG-5, Umarex HK MP5 .22 models. A favorite of LE/Military units, firearms dealers, shooters & operators as they do not have to carry 3-4 different models to fit different weapons platforms. The MFI mount takes less than 3 minutes to mount on your rifles or pistols. Please note: This was a sperate model that was made specifically for these two brands of .22 firearms and was machined to fit both brands as a “universal” mount. Only the MFI mount offers this flexability.
