A semi-automatic flywheel blaster designed for .50 full length foam darts.

Extra options exist for a crappily designed optional foregrip and mount that replaces the central front component of the magwell, a 14mm tightbore cage option, and battery tray sizes ranging from 16mm of height to 24mm of height.
