OI-M3-W3303 75mm Pump-Action Gauss Cannon

The OI-M3-W3303 75mm Pump-Action Gauss Cannon is an alternative primary firearm for the M3 Gekido that is intended to act as a close-range shotgun-style weapon for frames; similar to the OI-M3-W3302 25mm Automatic Gauss Cannon, it uses two HONEY BURST units to provide the power necessary for propelling its ammunition downrange and significantly boost the performance of the chemical propellant.

About the 75mm Pump-Action Gauss Cannon

The weapon is constructed of Durandium Alloy reinforced with a triangular ADNR lattice - similar to the OI-M3-W3302 25mm Automatic Gauss Cannon - and is designed with several recoil reduction mechanisms and numerous buffers to protect the weapon and the unit firing it from being damaged. It is designed primarily to be manually actuated with a large pump in order to cycle in the next round.

Though similar in operation and appearance to a human-scale shotgun, the 75mm Cannon is a precise heavy anti-armor weapon intended for use against fortifications, frames, mecha, and other heavily-armored units.
