Some Aids to Correct Aiming
BY HORACE KEPHART
IN the last July-August issue of OUTING there was a letter from an old-timer describing a “one lens telescopic sight” that he had mounted on his rifle and that not only magnified the image of the object aimed at but also gave him clear definition by eliminating blur. The lens attached to the front sight was used in combination with a small peep hole in the rear sight, which serves as a substitute for a lens, as in pin-hole photography.
The principle on which this contrivance works has been explained by two of our correspondents, one of them a physician and the other an optometrist.
Recently I received a catalogue of shooting accessories from A. G. Parker & CO., Ltd., of the Bisley Works, Whittall Street, Birmingham, England, that describes an optical sight made on a similar principle, which can be used with or without the ordinary front sight on the rifle, and in conjunction with either a fine peep-hole or a clearing lens in a rear sight on the rifle tang.
144987
There are three lenses that interchange in the hood that clamps on the muzzle; one a plain lens to use in conjunction with the blade, bead, or barleycorn front sight that comes with the rifle; another with a black spot in the center of the lens for hunting, when the common front sight is disregarded; and a third with a ring on the lens, to be used like an aperture disk in target shooting, the bull's-eye being centered within the ring.
The hood is attached by clamping with a broad headed screw that is slotted wide so that a small coin can be used to turn it, instead of a screw-driver. A milled nut at the back holds the lens in position and allows spare lenses to be easily substituted.
If no lens is used in the rear sight it is necessary that the peep-hole should be no larger than .03 or .04 inch. So small a hole cuts off much light; so it is better to add a clearing lens in a special holder screwed to the back of the tang sight, as shown in Fig. 3, in which case any size peep may be employed.
144988
The magnifying power of this optical sight is three diameters. The price of the front hood with spare lenses, in England, is 155. 2d; of the rear clearing lens and holder, 4s. (not including tang sight.)
The front hood is made for B.S.A., L.S.A.. and Greener rifles. It will be fitted to most other makes of rifles at SS. each extra.
144989
The clearing lens is fitted to the No. 8 B.S.A. aperture back sight, which is priced at 175. 6d.
Old riflemen, whose eyes are far sighted, could have lenses fitted by their Opticians that would suit their own eyes and make rifle shooting once more as much a game of skill as it ever was.
The B.S.A. sights (and rifles) are sold in this country by the Production Equipment Co., 5 Union
Square, New York. Perhaps this firm would import the optical attachments for their customers.
