Already in the market is the anticipated Sten Mk5 GBBR from Northeast Airsoft. The Sten is the SMG used by British paratroopers in World War II as well as in other conflicts after. The MK5 comes with a wooden stock and wooden vertical foregrip. The Northeast Airsoft version is an open bolt gas blowback with semi and auto fire modes and uses a Marui-spec Hop-up. Jonathan Higgs of Airsoftology does an unboxing and review of this GBB SMG.
