Abstract
A laser sight for a firearm (10) having a recoil spring guide (15) mounts components on the spring guide so that a light beam (18) is directed along the axis of the spring guide. This automatically makes light beam (18) parallel with the barrel (11) of firearm (10). Several mounting alternatives are possible, including a collimating lens (21) arranged on the axis of the spring guide to receive light from a laser diode (20) that is either mounted on the spring guide with the collimating lens or mounted remotely and arranged for directing light to collimating lens (21) via a fiber optic cable (25). These arrangements can also conceal the laser light within the firearm, where it is well protected and not noticeable.
Claims18
A firearm having a laser sight and a mechanism using a recoil spring guide, said firearm comprising:
- a. A laser diode mounted in a concealed position within said firearm;
- b. a collimating lens arranged for collimating a beam of light from said laser diode;
- and
- c. said collimating lens being mounted to direct said beam forward of said spring guide on said axis of said spring guide, so that said beam is thereby parallel with the barrel of said firearm.
In a firearm having a laser sight system and a recoil spring guide, said laser sight system producing a beam of light parallel with the barrel of said firearm, the improvement comprising:
- a. an emanator of said beam being mounted on said spring guide so that said emanator directs said beam forward of said spring guide on an axis of said spring guide;
- b. a laser diode providing light for said beam;
- and
- c. said emanator including a collimating lens receiving light from said laser diode.
