Abstract
A boresight device for calibrating a firearm and insertable into a chamber of the firearm. The boresight device includes a housing, a light-emitting assembly, and a magnet. A boresight device for calibrating a firearm is insertable into a chamber of the firearm. The housing is configured to be placed in the chamber of the firearm, the housing defines an emitting surface at a first end. The light-emitting assembly is received in the housing and is configured to emit a light beam out of the firearm when the housing is placed in the firearm. The magnet is attached to the housing. The magnet is positioned to magnetically engageable with a portion of the firearm, and the magnet is movable relative to the chamber.
Claims18
A boresight device configured for calibrating a firearm, insertable into a chamber of the firearm, the boresight device comprising:
- a housing configured to be placed in the chamber of the firearm, the housing defining an emitting surface at a first end;
- a light-emitting assembly received in the housing and configured to emit a light beam out of the firearm when the housing is placed in the firearm;
- and
- a magnet attached to the housing,
- wherein the magnet is positioned to magnetically engageable with a portion of the firearm, and the magnet is movable relative to the chamber;
- and
- wherein the magnet is positioned on a rear end of the housing and is configured to magnetically engage with the firing end of the firearm such that when the firing end moves away from the chamber, the boresight device moves together with the firing end thereby moving the boresight device out of the chamber.
A firearm calibration system comprising:
- a firearm comprising:
- a main body;
- a barrel installed inside the main body, the barrel having a chamber configured for receiving a cartridge and a muzzle;
- a sighting device mounted on the main body;
- and
- a firing end located beside the chamber, configured for firing the cartridge, and movable relative to the chamber;
- and
- a boresight device comprising:
- a housing inserted into an end of the chamber which is beside the firing end;
- a laser received in the housing for emitting a light beam externally from the firearm via the muzzle of the barrel;
- and
- a magnet attached to a rear end of the housing and attracted by the firing end;
- and
- when the firing end moves away from the chamber, the boresight device moves together with the firing end thereby moving the boresight device out of the chamber.
A method for calibrating a firearm, the method comprising:
- providing a firearm comprising:
- a main body;
- a barrel installed inside the main body, the barrel having a chamber for receiving a cartridge and a muzzle;
- a sighting device mounted on the main body;
- and
- a firing end located beside the chamber for firing the cartridge and movable relative to the chamber;
- and
- inserting a boresight device into the chamber comprising:
- a housing configured to be inserted in an end of the chamber which is beside the firing end;
- a laser received in the housing for emitting a light beam externally from the firearm via the muzzle of the barrel;
- and
- a magnet attached to the housing and attracted by the firing end;
- and
- activating the boresight device to emit the light beam through the muzzle so as to form a light spot on a target located at a predetermined distance;
- adjusting the sighting device to align an aiming point of the sighting device with the light spot;
- moving the firing end towards a direction away from the chamber and driving the boresight device to move out of the chamber by magnetically engaging with the firing end.
