This Chester County Armory listing is for a phenomenal, new condition Heckler & Koch MP5SD 9x19mm Parabellum transferable Fleming HK sear submachine gun with a removable RDTS Mfg. integral HK MP5SD-HE silencer.
Freshly built by renowned HK Gunsmith Ralph Smith Sr. of RDTS Manufacturing, this NFA transferable submachine gun setup consists of an excellent condition Fleming Firearms HK sear newly installed into a brand new Heckler & Koch 4-position ambidextrous Navy pack with 0,1,3,F firing positions. This pack has been professionally clipped and pinned for use on a shelf gun. It was then nestled into an also brand new condition SP5L host pistol that has been changed into an HK MP5SD pistol configuration by RDTS. This German manufactured and imported host weapon has properly had the bolt blocks professionally removed by Ralph Smith for use with this NFA sear. With removal of the denial block for use with this sear, this model will accept standard MP5 spec full-auto bolt carriers, and does not need an additional trip section or non-factory HK parts installed to work properly.
To setup this host weapon to original HK factory MP5SD specifications, RDTS also turned down the original factory barrel to the correct SD length and properly ported and threaded it for integral suppressor use. The installed suppressor is RDTS’s MP5SD-HE 12″ silencer, made to original HK factory specifications, but with an improved baffle system by Ralph that makes this setup even quieter than the HK original. This host weapon also features all of the proper MP5SD upgrades, including the a paddle magazine release and being properly remarked to “HK MP5SD.” The Fleming Firearms HK sear is NFA registered independently of the host weapon, and is not married to the host gun.
Overall, this beautiful transferable submachine gun setup is in like new condition both mechanically and cosmetically. It has been test-fired by RDTS and runs flawlessly with standard 9x19mm SAAMI spec ammunition. All parts and components except for the Fleming sear itself are in factory new condition and have not been fired outside of the testing and setup by RDTS.
