摘要： A breaching tool is powered by a blank cartridge in a breaching gun and includes a barrel, a propulsion assembly in the barrel, and a spring assembly around the barrel. When the cartridge is discharged in a chamber in fluid communication with the barrel's bore, pressure produced by the discharged cartridge propels the propulsion assembly forward from a ready position to an extended position, forcing a ramming head forward. The spring assembly has a compression spring in a spring can that biases the assemblies and ramming head back to the ready position. The breaching tool also includes a handguard that extends over and past the barrel's proximal half and surrounds a rear portion of the spring can. When used with a semiautomatic breaching gun, the breaching tool includes gas block over a gas port in the barrel, and a gas tube extends back to the breaching gun's bolt carrier group.
