A novel dearmer enables EOD technicians to propel dearmer projectiles using conventional electric .50 caliber blank cartridges or conventional non-electric 12 gauge blank cartridges. The dearmer projectiles may render energetic threats safe without requiring an opposing force to offset the recoil. The conventional blank cartridge functions as a rocket motor that supplies gas to a converging/diverging nozzle. Alternatively, liquid is loaded into the dearmer (creating a liquid rocket effect) and the EOD projectile is propelled toward a target from the end of the dearmer opposite the liquid.

A blank-only machine non-firearm includes a replica shell and replica barrel from a non-firing replica machinegun, such as an airsoft replica machinegun. An insert that defines a receiver may be inserted into and contained within the interior volume of the replica shell. An exhaust gas barrel is attached to the receiver and extends within the replica barrel. The replica receiver and barrel are configured to fire blank cartridges and not to fire live rounds. Noise and flash from a firing blank cartridge is directed from a chamber defined by the receiver to the exhaust gas barrel and hence to the replica barrel.

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.
