Abstract:
A magazine for a firearm comprises a tubular magazine body defining a cavity for holding cartridges, a spring, and a follower biased by the spring for dispensing cartridges from the magazine. A spring base disposed on the body includes a cantilevered resiliently deformable spring arm supporting the spring in one embodiment. The base is held in place by the floor plate. Sliding the floor plate onto the magazine body engages an inclined ramp of the floor plate with spring arm which automatically moves the spring arm from an undeflected to deflected position. When the floor plate is fully coupled to the magazine tube such that the spring arm clears the ramp, the spring arm snaps back to the undeflected position and locks the floor plate in place on the tubular body via interlocked retention features without use of tools.
