Testing the waters on a Classic Army MP5A4 that a buddy of mine is trying to sell. He got it in an estate sale, and I tested it out to make sure it cycles. The gun is in reasonable condition and cycles properly, but I do not know the history on the gun (i.e. how many rounds have been put through it). The butt plate needs to be replaced, and it currently is wired with Tamiya connections. All reasonable offers will be considered.
