M-37 Falcon: Alliance Grenade Launcher Rifle
Mini-Grenade Support Weapon
The M-37 Falcon was a Systems Alliance assault rifle that launched 25 millimeter mini-grenades instead of conventional rounds. Lighter and more accurate than most grenade launchers, it relied on a field fabrication kit to produce its specialized ammunition, leaving thermal clips as its only real constraint.
The M-37 Falcon was an assault rifle fielded by the Systems Alliance that broke from the conventions of its class by launching small explosive grenades rather than firing solid rounds. Lighter and more accurate than most grenade launchers, it gave infantry a portable source of area fire that could be carried and aimed much like a standard rifle.

Design and function#
The Falcon was built around 25 millimeter mini-grenades, trading the high rate of fire of a conventional rifle for explosive munitions that could strike an area rather than a single point. Despite this, it remained lighter and more accurate than most grenade launchers, retaining the handling of a standard rifle while delivering the effect of a heavier support weapon. (Mass Effect 3; Mass Effect: Andromeda)
Its supply system set it apart further. A field fabrication kit generated the rifle's specialized ammunition on the spot, sparing its user from carrying large stocks of grenades. The weapon also accepted standard thermal clips, and with the fabrication kit producing its rounds, those clips were the only practical limitation on how long it could keep firing.
