A large format launcher that is a modified rifle wherein the lower receiver is combined with an upper receiver into a unified receiver and modified to fit large-format flares. It is a single-shot, non-automatic reloading device, slam fire flare launcher device. The gas tube from an unmodified rifle is removed from the upper receiver disabling the bolt carrier group from automatic operation. The gas port is plugged and welded closed which prevents an operational gas tube from being installed on the launcher. The outer tube is pinned with a non-removable hardened pin. A single blank cartridge is fed into the launcher via a ten-round modified magazine. Manual cocking of the charging handle is required between firings. The ported gas barrel / plug, manufactured specifically for this launcher, employs an external hardened end with offset hole with welded plug enabling acceptance of a blank round only. The plug prevents any projectile from passing through the ported gas barrel and prevents the firing of live ammunition. With only gas from the blank passing through the barrels, the flare is launched and propelled approximately 300 feet and lights the flare with appropriate delay to function.
