Maniek44 goes over the Ascend Ninja 23 NBB Pistol if it is a good alternative to the Tokyo Marui MK23 and its clones. This is a non-blowback gas pistol with a CNC aluminium slide that can mount RMR sights and has red and green fibre optic sights for low light aiming. It also has a +16mm threaded outer barrel and a wheel hop design that can be adjusted through the slide without tools.
