The TM PSG-1 is one of the greatest sniping platforms in airsoft. This gun truly replicates and represents the PSG-1 in all respects. Range, accuracy, power and realism, it has it all.To start, this was one of Tokyo Marui's first gun with electronic blow back, so each shot you make will make the bolt move! The PSG-1 also features a true cocking mechanism. When the cocking lever is pulled all the way back, it will move the air nozzle to load the next BB. The most unique feature of this gun is its special gearbox. Tokyo Marui specifically made this gun to be a true semi-automatic sniper rifle, and to do this, an extended gearbox with a "pre-cocking" mechanism was designed into the PSG-1. With this in mind, you will have almost no trigger delay! After all shooting is done, a special release lever will reset the piston to "rest" position. This is a truly great gun. Highly recomended for any airsofter who wants a semi-automatic sniper rifle that can really deliver.
