Airsoft Entrepot reviews the STTI MK23 Non-Blowback Pistol. A hard hitting pistol, this is based on the popular Marui SOCOM 23 NBB Pistol though it does not come with a case and a LAM unit. You will need a universal holster to holster this as it is hard to find a holster specifically made for it... "The MK23 STTI is a NBB, for 'Non BlowBack', ie the breech does not move during the shooting. This makes the replica particularly discreet, making it a good choice for snipers. It is also a very cheap replica, which can be an interesting choice for players with a small budget!"
