Post Sample HK MP5A3

I have for sale a Post 86 Heckler and Koch MP5A3. This is availible only to Law Enforcement Departments (Not Officers) and FFL/SOT holders with a Demo Letter. If you aren't one of the above then you cant buy it. I have had this for 2 years and it came to me with a fixed stock and burnt out Surefire handgaurd. It is an older one as it has only the three lug mount and is not threaded, also stamped made in W. Germany. The grey finish is Duracoat sprayed over the original black, it showed wear so I wanted to keep the rust off it. I fitted a Dakota Tactical M-Lok rail and then sprayed everything durakote grey except stocks. It comes with 2 HK 30 round magazines, both old school straight ones, a 3 point sling from a Zenith, the screw on sling loop takedown pins, a HK parts optic mount, a Magpul VFG, and one A2 stock that came with it and the POF A3 stock pictured. I am keeping the Surefire pictured and the handstop. This is on a Form 3 in my shop but I don't shoot it much since I got a post sample trigger pack and a K clone. I am open to trades or partial trades in either post sample AR lowers, post sample AK 47s, Accuracy International, Surgeon, Or GA Precision (or comparable quality) bolt guns, or high end FFP scopes. Thanks for looking, oh and I am not giving up my SOT so manufacturers will need a letter. I got tons of pictures of this gun on my Instagram also and the UMP stock isn't included. Will ship in a Blackhawk Discreet Raquet Ball case.
