This is all-HK carbine that I built with an HK lower I bought years ago, then later purchased an HK complete upper that is stamped MP5-N. All parts are genuine HK.
It is in excellent condition. Since I have owned it I only put about 300 rounds through it. It has been safe kept. Included with the carbine are 8 genuine HK curved magazines.
Greater Houston area.
$4000 + shipping, or FTF in East Texas. PMO or Paypal (+4%). The first person to get me the funds takes it.
