A rotary-cylinder grenade launcher holding six 40mm rounds, built with the overengineered brutality that characterizes all Arcturus ordnance. The GL-6 uses a clockwork-style mechanical action — no electronics, no batteries, no firmware to hack. Each cylinder position accepts any standard 40mm casing, allowing operators to load mixed payloads: fragmentation, incendiary, smoke, flashbang, and chemical in whatever combination the situation demands. The weapon's nickname 'Sermon' derives from the practice of loading all six cylinders with different munition types — operators call it 'preaching the full gospel.'

The GL-6's mechanical simplicity makes it the preferred launcher for operations in EMP-hardened environments or against targets with electronic warfare capability. While competitors have introduced smart-linked launchers with programmable airburst and guided munitions, the Sermon continues to outsell them in actual combat deployments because it always works. No boot sequence, no calibration, no network dependency. Point it at the problem and pull the trigger six times.
