Semi-Auto with a Auto Mag release

[MachIVshooter]

Yes, but only if there were a method to easily disable these functions. Maybe an unobtrusive lever or perhaps a screw that could be turned one direction to enable the functions but turned another way to disable them.

This.

It could be a useful feature, but there is limited application. Empty magazines can usually handle falling the 4-1/2 feet or less from shouldered position without damage, but I don't drop my magazines on the ground for the most part just because they will ineviteably collect dirt and debris that can affect reliability.

I would spend a little more for this feature on, say, an AR, but only if it was selectable, and only if it proved to work well.

No on the self ejecting mags. I like the option to either let them fall and speed reload, or reload with empty mag retention. As for automatic bolt close on inserting a loaded magazine, I do approve of that, with the caveat that there is still a manual bolt-release lever.

A CZ40b I had would auto-close on every loaded mag when it was clean. After it got some carbon and crud in it, not as much. I thought it was a really handy malfunction.

I like the idea in principle, but I very much doubt the associated issues would work as well in practice. I've tripped over nothing, let alone falling magazines in a firefight.

I've heard that the "ping" of the Garand on firing the last round was a liability as it told the enemy you were out of bullets. Supposedly some soldiers did take advantage of this by simulating the ping to trick the enemy into charging when the gun was fully loaded.

If an enemy soldier could hear the ping after eight rounds of .30-06, well, maybe the whole Ubermensch idea had something to it.
