The TSD SD700 Spring Rifle is an airsoft sniper rifle and copy of a Tokyo Marui VSR-10. As such, it can be upgraded with the same parts as the Marui VSR-10. However, it shoots 400 fps out of the box, so it's not necessary to upgrade it. We recommend a good 3-9x scope to go with this gun. Also known as the M700 sniper rifle. This version comes with Olive Drab (OD) Green furniture on it.
Some of our TSD Rifles may be equipped with a velocity reducer that limits the velocity to 400 fps with 0.20g BBs. This restrictor can be removed from the end of the air nozzle to increase the velocity to around 480 fps. If your TSD Rifle did not come with a restrictor, it should shoot around 480 fps without modification. Please contact us if you have any further questions.
