Your post isn't clear. If you are looking for a real MP-5 (submachinegun) I would suggest posting under the NFA Firarms and parts heading and plan to spend $10-12,000 if you can find one. If you are looking for a semiauto, try contacting Bobcat Weapons (480)832-0844 or at their website www.bobcatweapons.com. Also keep in mind, if you have a foreign (HK) parts kit, the 10 parts "sporting use" ban is still in effect. I'm sure the people at Bobcat can explain it to you. If I can be any help please drop me an email. Good luck with your project.
