What is Slam fire

Slam fire is a feature certain nerf blasters have (primarily springers). This feature is mainly found in stock blasters (Tri strike, Roughcut, Villanaitor, surgefire, e.t.c) but there are some exceptions like the slamfire Talonclaw project and the Lynx. This allows people to hold down the trigger and prime the blaster, and once it is primed it automatically fires, which increases rate of of fire by quiet a bit.
