High-powered airsoft electric guns shoot at about 300-400 FPS (feet per second), and deliver great power for those who are in need of such a weapon, whether for backyard shootouts, airsoft games, realistic target practice, tactical training, airsoft competitions, or mil-sim exercises.  All of these come with full metal gearboxes, full metal gears, and metal barrels for power and accuracy that is unmatched by other cheaper models of airsoft.  Most of these are heavily weighted to accurately resemble their real counterparts ounce for ounce.
