Self-leveling follower for an ammunition magazine
View Patent ↗The present invention is a self-leveling follower for an ammunition magazine. Side extensions provide greater stability to the follower and aid in its self-leveling feature. The follower according to the present invention is also manufactured to facilitate removal from and insertion into the magazine casing when maintaining the magazine. Additional features provide greater utility by improving bolt-stop capacity and consistency of ammunition feed.

d. a spring nub projecting downward from the floor on a bottom of the floor;
e. at least one spring retention wall on the bottom of the floor;
f. a front end extending downward beyond a level defined by the spring nub; and
g. a hind end extending downward beyond a level defined by the spring nub.
2.

3. The follower of claim 2 , the ramp extending towards a fore side of the follower for at least 40% of a length of the follower.
4. The follower of claim 3 , θ having a measurement under 1°.
5. The follower of claim 4 further comprising a bolt stop shelf projecting upwards from a hind side of the follower.
6. The follower of claim 5 , the bolt stop shelf being an elevated ledge, extending no more than 0.01 in. from a level of the floor.
7. The follower of claim 3 further comprising a bolt stop shelf projecting upwards from a hind side of the follower.
8. The follower of claim 7 , the bolt stop shelf being an elevated ledge, extending no more than 0.01 in. from a level of the floor.
9. The follower of claim 2 further comprising a bolt stop shelf projecting upwards from a hind side of the follower.
10. The follower of claim 9 , the bolt stop shelf being an elevated ledge, extending no more than 0.01 in. from a level of the floor.
11. The follower of claim 1 , the ramp extending towards a fore side of the follower for at least 40% of a length of the follower.
