Rare MP5 clone in 357 Sig. Not 9mm, not 40, not 10mm. Yes, this one is chambered in 357Sig. From what I understand, very few of these were made  from demilled HK MP5 kits originally chambered in .40 S&W.  Can be converted back to a .40 with just a barrel swap by a competent gunsmith. No other parts would need to be changed. You'll probably never see one of these for sale again.


With its pinned and welded barrel extension, it's already in rifle configuration so you're good to go putting a MKE or real HK A3 collapsible stock on it without going through the SBR hassle. Includes two original HK mags, one aftermarket mag, and a fake SD shroud for the barrel and handguard. I also have a box or two of ammo I'll include. 


As this caliber was never a HK factory option, many of these aftermarket builds required some tinkering to cycle reliably. This particular one needs no tinkering and runs flawlessly. Gun has less than 250 rounds through it. Can send additional pics and live fire videos of the gun. Message me through the Armslist system or text me at REDACTED for additional pics or information
