Abstract

Official abstract text for this publication.

A magazine assembly having an elongated housing with a channel dimensioned to contain a plurality of stacked ammunitions between a first and second end of the housing. A spring loaded follower is mounted within the housing channel and is adapted to abut against one end of the stacked ammunition adjacent the second end of the housing and urge the stacked ammunition towards the first end of the housing. A tactile indicator assembly is mounted to the housing which cooperates with the follower to indicate the position of the follower between the ends of the housing and thus the amount of ammunition remaining in the magazine.

First claim

Opening claim text (preview).

I claim: 1. A magazine assembly comprising: an elongated housing having a channel dimensioned to contain a plurality of stacked ammunition between a first and second end of said housing, a spring loaded follower mounted in said housing and adapted to abut against one end of the stacked ammunition adjacent said second end of said housing and urge the stacked ammunition toward said first end of said housing, a tactile indicator assembly comprises a plurality of pins movably mounted to said housing at longitudinally spaced intervals between said first and second ends of said housing, in both a front and rear portion of said housing, said pins being movable between an extended and a retracted position, a resilient membrane associated with each pin which urges its associated pin toward a retracted position which urges each of said pins to said retracted position of each of said pins, and wherein said follower moves said pins via an attached ramp to said extended position when said follower is aligned with said pins said pins abut directly against said follower when aligned with said follower mounted to said housing, said tactile indicator cooperating with said follower to indicate the position of said follower between said first and second ends of said housing, the magnet being affixed to a rear portion and a front portion of said follower to communicate with pins in order to allow a user to ascertain the remaining rounds in the magazine assembly while the magazine is inserted into a partially obscuring magazine well of a firearm and said resilient membrane disposed between said ramp and said pins.
