US12326314 - Gun magazine base pad with cantilever spring latch mechanism

A firearm magazine base pad having a significantly reduced overall height. The base pad is slidably engaged to the bottom of the magazine tube-thereby securing a magazine spring and follower inside the tube. A plunger latch mechanism is provided to lock the base pad in place. The plunger can be depressed in order to release the base pad and allow it to slide free of the magazine tube. The plunger is biased upward by a lateral cantilever spring. A fixed end of the cantilever spring is attached to the base pad. A free end of the cantilever spring moves with the plunger.

firearmmagazinebase pad

The patent describes a firearm magazine base pad that features a reduced height and a plunger latch mechanism, allowing for easy attachment and detachment from the magazine tube. The design includes a cantilever spring that biases the plunger upward to secure the base pad in place while enabling quick release when needed.

Claim 1

A base pad configured to be slidably attached to a tube, comprising: (a) a body with a front, a first lateral side, a second lateral side, a back, and a floor; (b) said body opening into a vertically-oriented plunger bore; (c) a plunger slidably mounted within said plunger bore so that said plunger moves up and down within said plunger bore; (d) a horizontally-oriented cantilever spring having a fixed end and a free end; (e) said fixed end of said cantilever spring being connected to said base pad; (f) said free end of said cantilever spring being connected to said plunger so that said free end moves vertically with said motion of said plunger; and (g) said cantilever spring urging said plunger upward so that said plunger protrudes out of said bore and inhibits motion between said body and said tube. (a) a body with a front, a first lateral side, a second lateral side, a back, and a floor; (b) said body opening into a vertically-oriented plunger bore; (c) a plunger slidably mounted within said plunger bore so that said plunger moves up and down within said plunger bore; (d) a horizontally-oriented cantilever spring having a fixed end and a free end; (e) said fixed end of said cantilever spring being connected to said base pad; (f) said free end of said cantilever spring being connected to said plunger so that said free end moves vertically with said motion of said plunger; and (g) said cantilever spring urging said plunger upward so that said plunger protrudes out of said bore and inhibits motion between said body and said tube.
