The latest gas blowbacks from KWA, the KZ.61 SMG and the AKG-74SU are now available at Airsoft Outlet Northwest... "KWA Airsoft finally dropped a couple of their new releases, and we managed to get a handful of them in stock. The AKG-74SU is a compact gas blowback AK model with full metal construction and a side-folding stock. These are loud and really fun to shoot.
