Anybody know the history of the anti-tilt follower?
The Army found that some (not all) of ONE brand of magazine (Sanchez Enterprises) was unreliable in FULL AUTO fire. The magazines were in-spec, but could never figure out what the cause was. The magazines were used as a test-bed for the green anti-tilt followers, and the problem went away.
Since most people will never use Sanchez Enterprises magazines (they no longer manufacture magazines) and never use them in a full auto/burst rifle, anti-tilt followers are not a requirement in my opinion.
I, personally, would not have an issue using a magazine without anti-tilt followers, as long as the magazine was manufactured by a reputable magazine manufacturer, and otherwise proved reliable. That being said, anti-tilt followers are cheap and easy to swap out, and may provide an important psychological comfort.
