ASG Boost 30000 RPM (30K) Long Motor (high torque). A solid 16 TPA CNC quality motor for very heavy duty upgrades.  Can use this motor in any custom upgrade gearbox build up to a M150 spring. Made of high quality components, the BOOST style is an excellent choice to most guns.  While not as robust or efficient as the Infinity series, the Boost is still a solid motor that competes with SHS and other types.  This is considered a high torque motor while retaining a higher ROF speed for guns.

30,000 RPS

16 TPA Rating (faster speed and less torque than the U-22000)

Long axle type for most guns, most notably M4 guns.
