1 Claim. (01. 33-47) This invention relates to sights for firearms, and particularly to front sights of the so-called hooded type.

Sights of this type comprise a tubular hood hood I is slotted transversely from the top, the slot I 5 constituting about one-half the circumference of the tube. It should be noted that the slot is a simple transverse out, without longitu- 5 adapted to house the sighting element, protecting dinal projections, bevels or other additional parts 5 the sighting element from accidental displaceor surfaces. Said slot I5 is adapted to receive ment and likewise shielding it from such direct a sight member or reticule which, according to light as would be reflected or refracted in such a the present invention, is held in the slot and in manner as to interfere with the proper use of the proper relation to the hood by its own resilience.

The reticule is thus held illustration includes a base portion II, said base correctly positioned vertically and laterally, the portion projecting a considerable distance to the lower edges of the ears I8 preventing abnormal rear and a shorter distance forward from the downward displacement and the margins of the 50 hood proper.

When an upward pressure is exerted on these ears, the displaced portions 20 and 2| are cammed back into the plane of the ring and into alignment with slot l5 due to the camming engagement of their arcuate periphery with the arcuate interior surface of the hood. Means have thus been provided for removably locating the reticule correctly within the hood without the assistance of any parts other than the hood and reticule themselves.

The form of the invention shown and described is to be understood as illustrative only, the invention being susceptible to embodiment in many other forms, all falling within the scope of the appended claim, which is to be broadly construed.
