Heckler & Koch MR223A3 5.56mm NATO Transferable Machine Gun in Factory RAL8000 Finish


Status: In-Stock / Please Call to Purchase

This Chester County Armory listing is for an extremely rare, fully select fire version of a Heckler & Koch MR223A3 5.56mm NATO transferable machine gun. 

This model started its life being imported into the United States as a rare 14.5″ HK semi-automatic pistol. The RAL8000 finish was done by Heckler and Koch, themselves, and is not an aftermarket finish. This pistol was then transformed into a host gun with an NFA registered, fully transferable SWD Lightning Link that was installed by famed Lightning Link specialist John Ciszek of JEC Enterprises. John is known throughout the industry as “The Lightning Link Guy” because of extraordinary work making these custom setups run absolutely flawlessly! His work on this gun is no exception, as it is now a fully select fire setup that runs just like it came from the HK factory that way!

This incredible specimen also features the factory correct HK factory front and rear back up iron sights. It also features the correct RAL8000 matching HK furniture and comes with a current generation HK Gen 3 30rd magazine, also in the RAL8000 finish. 

The host pistol is being offered as new condition, having only been fired by JEC Enterprises during the installation and testing of the SWD Lightning Link.  It does note some minor handling-type marks on the exposed section of the barrel in the parkerization (see photos) however this was the condition in which it was originally imported. This weapon setup is only being offered for sale complete, and will not be separated by us. 

This NFA registered SWD Lightning Link is fully transferable and is currently on a Form 3. The HK MR223 acting as a host gun will transfer as a standard Title One pistol.
