Front Sight for a Firearm
Abstract
A firearm has a barrel with an open front sight located on a
muzzle end of the barrel and a rear sight located on the barrel a
distance away from the front sight. The front and rear sight
cooperate with each to enable a user to aim the firearm. The front
sight has a first targeting indicia with a center. The rear sight
has targeting indicia that cooperates with the front sight first
targeting indicia to allow the user to aim the firearm. The front
sight has second targeting indicia comprising a scribe line at the
center of the first targeting indicia. The scribe line is visible
from the rear sight when the front sight first targeting indicia
and rear sight targeting indicia are brought into register. The
user may focus the scribe line on the target for further precision
in aiming the firearm.

the barrel spaced from the front sight, wherein the front sight has
a first targeting indicia with a center, wherein the rear sight has
targeting indicia that cooperates with the front sight first
targeting indicia to allow the user to aim the firearm, wherein the
front sight has second targeting indicia comprising a scribe line
at the center of the first targeting indicia, wherein the scribe
line is visible from the rear sight when the front sight first
targeting indicia and rear sight targeting indicia are brought into
register; bringing the front sight first targeting indicia into
register with the rear sight targeting indicia while aiming the
firearm; and bringing the front sight second targeting indicia onto
a target while maintaining the front sight first targeting indicia
and the rear sight targeting indicia in register; wherein the rear
sight targeting indicia cooperates only with the front sight first
targeting indicia, and wherein the front sight scribe line may be
brought on target without simultaneous visual alignment of the rear
sight targeting indicia with the front sight scribe line.
12. The method of claim 11, wherein the scribe line is less than
0.005 inches thick.
13. The method of claim 11, wherein the first set of indicia on the
front sight comprises a dot.
14. The method of claim 11, wherein the front sight comprises a
post.
15. The method of claim 11, wherein the rear sight comprises an
open sight.
16. The method of claim 13, wherein the rear sight targeting
indicia comprises dots.
17. The method of claim 11, wherein the rear sight comprises a
notch.
18. The method of claim 11, wherein the front sight is removably
attached to the muzzle end of the firearm.
19. The method of claim 11, wherein the rear sight is removably
attached to the barrel of the firearm.
20. The method of claim 11, wherein the firearm is a pistol.
Description
BACKGROUND
[0001] Gun sights are mechanisms that allow the user to aim a gun
or firearm in order to hit an intended target. This disclosure
rates to an improvement to a firearm with open sights.
Particularly, this disclosure relates to an improvement to a
firearm with open sights including a front post or similar
structure.
BRIEF DESCRIPTION OF THE DRAWINGS
[0002] FIG. 1 is a perspective view of a front open sight at a
muzzle end of a barrel of a firearm;
[0003] FIG. 2 is a partial front elevational view of the front
sight of the firearm of FIG. 1.
[0004] FIG. 3 is a side view of the front sight of FIG. 1;
[0005] FIG. 4 is a top view of the front sight of FIG. 1;
[0006] FIG. 5 is an enlarged view of the front sight in register
with the rear sight; and
[0007] FIG. 6 shows alternate embodiments of a front sight in
register with a rear sight using the principles disclosed
herein.
DETAILED DESCRIPTION
[0008] Generally speaking, a majority of firearms with open sights
use a system of three dots for alignment. The open front sight has
targeting indicia, for instance, a post with a dot located in the
center of the post to facilitate aiming of the firearm. The open
rear sight has targeting indicia, for instance, a notch with a dot
located on each side of the notch, to facilitate aiming of the
firearm. In one example, in order to aim the firearm, the front
post is brought into register with the notch such that the three
dots come into alignment.
[0009] In order to provide further accuracy when aiming the
firearm, a second targeting indicia may be provided on the front
sight. FIG. 1 shows a firearm barrel 20 with a front sight 22
located at the muzzle end 24 of the barrel. The front sight 22 has
first targeting indicia 26, for instance, a dot on a post. The
front sight also has second targeting indicia 28, for instance, a
scribe line. The second targeting indicia 28 cooperates with the
first targeting indicia 26 to assist the user in aiming the
firearm.
[0010] As shown in the drawings, the scribe line forming the second
targeting indicia 28 may intersect a center point of the dot
forming the first targeting indicia 26. The scribe line of the
second targeting indicia 28 may extend from the center point of the
dot of the first targeting indicia 26 and project from the top of
the dot of the first targeting indicia when viewed from the rear
sight. Preferably, the scribe line for a hand gun has a thickness
or width of approximately 0.002 inches to 0.003 inches. The
thickness for other types of firearms may be varied as needed.
[0011] FIG. 5 shows the rear sight 30. The rear sight may be
located at the breech end 32 of the firearm or in another position
spaced from the front sight 22. The rear sight 30 has targeting
indicia that may comprise a notch 36 with a dot 38 on both sides of
the notch. In one example, when aiming the firearm, the first
targeting indicia 26 of the front sight is brought into register
with targeting indicia of the rear sight. A shown by example in
FIG. 5, once the three dots (26,38) are aligned, the user may focus
the scribe line 28 on a target for further precision in aiming the
firearm.
[0012] The principles of the disclosure may also be used with front
sights comprising posts, blades, or beads, and with and without a
dot. The principles of the disclosure may be utilized with front
sights that are adjustable or fixed or removably attached to the
firearm's barrel or integral with the barrel. The principles of the
disclosure may also be used with rear sights comprising notches
with a square, triangular, "V" or "U" shapes, and with and with
dots. Additionally, the principles of the disclosure herein may be
used with adjustable rear sights or rear sights that are removably
attached to the rear of the firearm. Although the figures and
description herein relate to open sights used on firearms, the
principles of the disclosure may be used in connection with a rear
sight having a peep hole. FIG. 6 shows alternate embodiments of
open sights where the first targeting indicia of the front sight
comprising a front post and the second targeting indicia of the
front sight comprises a scribe line. In FIG. 6 the target is
depicted by the gray circle indicated by reference character 40.
The firearms may include rifles, shotguns, and pistols.
[0013] In view of the foregoing, it will be seen that the several
advantages are achieved and attained. The embodiments were chosen
and described in order to best explain the practical application to
thereby enable others skilled in the art to best utilize the
principles disclosed herein in various embodiments and with various
modifications as are suited to the particular use contemplated. As
various modifications could be made in the constructions and
methods herein described and illustrated without departing from the
scope of the invention, it is intended that all matter contained in
the foregoing description or shown in the accompanying drawings
shall be interpreted as illustrative rather than limiting. Thus,
the breadth and scope of the present invention should not be
limited by any of the above-described exemplary embodiments, but
should be defined only in accordance with the following claims
appended hereto and their equivalents.
