The Vektor V.21 is the result of experiments with the Thermal Propeller Chip, licensed from OT. Its firing rate is quite unusual, and the modified Biovascular recoil absorbers make the gun easy to control. The choice of lightweight Notum alloys also seems to benefit the gun to a great extent. The .30 features 4 rows of vertical-running nano spurs and SemiSmart Nano input.
