I wondered if any one knew how the vector knock off of the Mp5k is comparabel in quaility to the h & K. I found a Vectok Mp5k Pistol grip, its classifed not as a rifle or pistol but any other weapon because it has a front grip; the guns price is $2500. Compared to a H & K MP5K with a factory coolant, 6 mags, lazer and thing that combines mags for $3,500. Which one should I go with? Is the Vector UZI for $900 a good buy. Could use some advice on what the best submachine gun is and where there sold?
