expensive to manufacture and efficient in operation.

For other objects and for a better understand-- ing of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a perspective view of a gun with the sight embodying the features of the present invention connected thereto,

Fig. 2 is a top plan view of the sight.

Fig. 3 is a side elevational view of the sight.

Fig. 4 is an end elevational view of the sight.

Fig. 5 is a bottom plan view of the sight.

Referring now to the figures, l0 represents a gun having a barrel I l on the rear end of which there may be mounted a gun sight l2 embodying the features of the present invention. A gun stock is connected to the rear end of the barrel as indicated at l3. On the forward end of the 1 barrel there can be releasably connected a front sight M. The rear of the barrel, as shown in Fig. 3, has screws [5 and I6 protruding upwardly from the top thereof and centering posts l8 and I9. Adapted to be fitted over these posts and screws is a main sighting piece 2| having a sighting groove 22 in the top of the same. The bottom face of the piece 2| has large openings 22' to receive the screws l5 and I6 and small openings 23 to receive the centering pins I8 and I9. The bottom face of the sighting piece is grooved to fit the top surface of the barrel and in flush engagement therewith.

Adapted to be threaded into the top of the barrel in a threaded opening 25 is a screw 26 having a large flat head 21. With the screw extended to a raised position, the piece 2| can be extended over the head, there being a slot 28 extending through the sides of the piece and a narrow slot extending from one bottom edge of the piece to accommodate the screw shank 26. This narrow slot is indicated at 29. The groove '22 is knurled as indicated at 3|.

By a simple operation, the sighting piece 2| can be placed upon the top of the barrel or removed therefrom. The screw 26 may remain in place and be adapted to receive other sighting pieces,

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

I claim:

1. A sighting piece adapted to be connected to a gun barrel comprising a grooved bottom face adapted to fit the top of the gun barrel, a transverse slot elevated from the bottom face and extending from one side of the piece to the other, a screw adapted to be fitted into the top of the barrel and having a head adapted to enter the transverse slot and extend from the opposite sides of the piece whereby the screw can be turned from the opposite sides thereof, and said piece having a narrow slot extending from one side of the piece for receiving the screw shank.

2. A sighting piece adapted to be connected to a gun barrel comprisin a grooved bottom face adapted to fit the top of the gun barrel, a transsighting piece having a top groove with a knurled bottom face.

3. A sighting piece adapted to be connected to a gun barrel comprising a grooved bottom face adapted to fit the top of the gun barrel, a transverse slot elevated from the bottom face and extending from one side of the piece to the other, a screw adapted to be fitted into the top of the barrel and having a head adapted to enter the transverse slot and extend from the opposite sides of the piece whereby the screw can be turned from the opposite sides thereof, and said piece having a narrow slot extending from one side of the piece for receiving the screw shank, and said bottom groove having depressions therein adapted to receive projections from the top face of the barrel.
