I'm working a trade deal for a customer police dept wanting to trade out 3 HK MP5-40 SMGS with extra mags and 2 HK 53 post 86 dealer samples for new firearms that I am providing. Will need LE demo request letters and it would be better to take all or one of each in the demo request letter. I can also cut the guns up and sell as a parts kit . Looking to get $2500 each gun delivered with accessories. Let me know of your interest. The guns are in very good condition.
