Abstract
Marksmanship training apparatus is used with air guns or weapons firing blank cartridges and comprises a housing member with an attached muzzle alignment tube for insertion into the bore of the barrel of the weapon and includes sealing apparatus around the muzzle alignment tube to minimize leakage of gas between the bore and the muzzle alignment tube and to prevent the gas from pushing the muzzle alignment tube out of the bore. The housing member includes a switch which is activated by the gas to complete an electrical circuit positioned in the housing to cause light energy to be emitted from the housing member.
