<p>A reversible magazine catch assembly (32) has a housing (40), a movable mounting pin (42) and a coiled spring (44). The housing has a spring channel (54) generally perpendicular to and intersecting a pin hole (56), and a magazine locking rib (52). The spring channel (54) is formed by drilling three parallel holes (58, 59, 62) into the housing at different directions to provide lateral support for the coiled spring (44). The spring biases the housing relative to the spin and forms a slidable friction hold of the pin. The pin has ledges (68, 70) that interact with the spring and housing to prevent it from being pushed out of the housing.</p> |
