These Heckler and Koch bolt carrier groups are all new, German manufactured. They will fit on any appropriate MP5, MP5K. These can be put on factory original guns, registered sear conversion weapons or registered receivers. These will may or may not fit on the semiautomatic versions of the MP5 or its variants. All the H&K bolt groups have become restricted items and are no longer available for private purchase. Only new German HK bolt groups imported into the United States prior to January 19, 2009 can be sold to private individuals or even Class 2 or 3 dealers. Any new H&K bolt group, imported into the United States, can only be sold to law enforcement or military agencies. We have a few of the remaining, registered new German H&K factory bolt carrier groups available. These items will only fit on H&K factory original guns. Once these units are gone, no more new German HK bolt carrier groups or trigger packs will be available.
