Self-illuminated firearm chamber

A firearm apparatus configured to fire at least one bullet of a cartridge, comprising:

• a barrel comprising an inner-barrel-diameter configured to receive the cartridge;
• a cartridge-chamber configured to receive the cartridge from an ammunition feeding unit and wherein said cartridge-chamber is formed by a number of wall surfaces;
• and
• the ammunition feeding unit comprising a firearm magazine comprising a pair of lips configured to house a next cartridge to be fired, wherein only the wall surfaces and respective upper surfaces of said pair of lips are coated by a self-luminous glowing matter to thereby illuminate only said cartridge-chamber so an inside of said cartridge-chamber is visible, when said cartridge-chamber is not enclosed, including in very low light (less than 200 lumen) to zero light conditions;
• a rear discharge opening formed behind said barrel, aligned with said barrel, the cartridge comprising a casing comprises a primer and encloses a sealed inner-casing space that contains gunpowder;
• and
• wherein upon activating the primer by a firing activator of the firearm apparatus, the primer explodes to thereby detonate the gunpowder, forming propellant gases inside the cartridge that are directed both forward and backward as follows:
• forward:
• firing of the at least one bullet via said barrel;
• and
• backward:
• pushing, by a recoil force Fp, the casing, being a counterweight to the at least one bullet, to thereby eject the casing from the firearm apparatus via said rear discharge opening and said cartridge-chamber,
• wherein another self-luminous glowing matter is enclosed inside an embeddable vial, wherein said embeddable vial has a light emitting window.

A firearm apparatus configured to fire at least one bullet of a cartridge, comprising:

• a barrel comprising an inner-barrel-diameter configured to receive the at least one bullet;
• a rear discharge opening positioned behind and aligned with said barrel;
• a cartridge-chamber comprising a plurality of wall surfaces, the cartridge-chamber being configured to receive from an ammunition feeding unit, the cartridge comprising a casing that comprises a primer and encloses a sealed inner-casing space comprising gunpowder;
• and
• the ammunition feeding unit comprising a firearm magazine with a pair of lips configured to house a next cartridge to be fired, wherein only the wall surfaces of the cartridge chamber and upper surfaces of said pair of lips are coated by a self-luminous glowing matter configured to only illuminate said cartridge-chamber;
• wherein upon activating the primer by a firing activator of the firearm apparatus, the primer explodes to thereby detonate the gunpowder, forming propellant gases inside the cartridge, the propellant gases being directed:
• a) in a forward direction by firing of the at least one bullet via said barrel;
• and
• b) in a backward direction by pushing, by a recoil force Fp, the casing, being a counterweight to the bullet causing the casing to be ejected from the firearm apparatus via said rear discharge opening and said cartridge-chamber.

A method of firing a bullet of a cartridge, comprising:

• upon activating a primer by a trigger of a firearm apparatus that comprises a barrel comprising an inner-barrel-diameter configured to receive at least one bullet, a rear discharge opening positioned behind and aligned with said barrel, a cartridge-chamber comprising a plurality of wall surfaces and configured to receive the cartridge from an ammunition feeding unit, the ammunition feeding unit comprising a firearm magazine with a pair of lips configured to house a next cartridge to be fired, wherein only the wall surfaces and respective upper surfaces of said pair of lips are coated by a self-luminous glowing matter to thereby illuminate only said cartridge-chamber so only an inside of said cartridge-chamber is visible, the cartridge comprising a casing that comprises a primer and encloses a sealed inner-casing space comprising gunpowder, the primer explodes causing gunpowder to detonate and form propellant gases inside the cartridge, the cartridge-chamber toward the barrel comprising the inner-barrel-diameter configured to receive the bullet, the gunpowder being in the sealed inner-casing space of the standard cartridge comprising the casing that comprises the primer, the cartridge-chamber comprising the plurality of wall surfaces and configured to receive the cartridge from the ammunition feeding unit;
• directing the propellant gases (a) in a forward direction by firing of the bullet of the cartridge via said barrel;
• and (b) in a backward direction by pushing, by a recoil force Fp, the casing, being a counterweight to the bullet causing the casing to be ejected from the firearm apparatus via a rear discharge opening and said cartridge-chamber, the rear discharged opening being behind and aligned with said barrel;
• illuminating, by the self-luminous glowing matter, only said cartridge-chamber when in a loading state.
