Which is stupid and will be beyond expensive

Or you could just bullpup the M16 and make it your carbine rather than having to make a new round

Though I admittedly don’t know much about that round

Literally change your bullet to one better suited for a short barrel, or adjust the rifling somehow.

Could still keep a decent amount of parts compatibility with a bullpup M16, but the barrel would be like 14" effective

Except it’s a bullpup

But still a 20" barrel

And worse than that it’s a bullpup *conversion*

There's nothing wrong with bullpups if you need a short gun and want to keep rounds made for a longer barrel

I mean most militaries are trying to get away from them

Including the early adopters

Honestly a mistake

Disagree

It's the only realistic way to maintain ammo compatibility between a rifle and a carbine

Without losing performance in one or the other ballistically

Or you could do what the US does and not care

Then spend millions on something dumb

And degrade the combat performance of your soldiers by issuing a weapon that is ineffective with its ammunition

OR

We could solve the issue by just adopting the G11

The cut down model without the weird box, it's a thin vertical rectangle of KSM

yes hello fuck the fall of east Germany

You should have waited a year

maybe two

Unironically

the west gets STGW 940 parts kits, and the G11

You get the same things you have now but a year later

I never knew the StG-940 existed and my life is somewhat better now.

They’re still out there somewhere

Most of the produced ones sorta vanished after the wall fell

I wonder if decreasing the twist rate of the M4 barrels would help increase the velocity.

Some terrorist in the Middle East is probably sitting atop a cache of them and doesn’t even know it

Oh probably

They have caches of third reich weapons and they just shitter squat on all of them

Fucking useless apes

Polygonal rifling at a lower twist rate.

But would it make up for 4" of barrel missing?

I mean, I don’t know

I know rifling is a precise science

I’m sure if they looked into it it would be easy but they won’t for some reason

I mean just swapping the M4 to polygonal rifling would give some pretty good performance increases, it's blatantly superior to traditional rifling.
