UMP conversions and Fixed UMP style stocks. UMP conversions have multiple options as well. The basic build can be done with an H&K USC and a stock adaptor Block. This type of build requires a UMP lower, UMP stock , UMP stock roll pin, stock block and a combination of 3 922R parts. Unlike the G36 conversions, The stock block set up doesn't add much to the LOP and is a great way to get the UMP look. For the H&K purist, The Rear section fuse job is the way to go. Adding a Real UMP rear section allows the lower to be removed with the factory takedown pin and is dimensionally correct to a real UMP. The average labor cost is $750 on this type of conversion and it requires a UMP rear section,take down pin, stock, stock axle pin ,lower ,mags and three compliance parts. The trigger, sear , followers and floorplates are the most popular , there are some barrels available as well. These parts can be found at hkparts.net. Please remember to check all your local , state and federal laws about the legality of any changes you make to your factory rifle (highcap mags, folding stock, pistol grip , etc..) Please contact us for the specific needs on Your UMP style build.
