Made to meet the requirements of special forces units the Heckler & Koch MP5SD 9mm integrally suppressed submachine gun delivers. Despite its integrated silencer element, it has the same length and shape as an unsilenced submachine gun and unlike most conventional silenced submachine guns it fires standard ammunition with the same effect, the use of special subsonic ammunition is not necessary. No wonder the MP5SD is one of the most accurate silenced submachine guns of its type. This item requires TWO tax stamps as it is designated a “Short Barreled Rifle” under the NFA and is integrally suppressed. We also have a Silencer Shop kiosk so filing your tax stamp with us is a breeze. If you would like more pictures feel free to ask!
