Abstract
Abstract A one-piece integrally formed bullet catch preferably formed of nylon comprising an open ended cylindrical casing having an inwardly extending flange at one end and an outwardly extending flange at the other end. Helical springs are integrally formed with the inwardly extending flange and with a hemispherical head which extends partially through the opposite end and is resiliently held with the integral springs under compression by a swaged tapered retainer member which has a circular line of contact with the hemispherical head and which is resiliently engaged with the hemispherical head to hold the hemispherical head against accidental movement.
