In 5.56 i think it would be useless.
If you go that short might aswell use a handgun.
If you need a carbine platform, use a pistol caliber with such short barrel or go 7.5" with a 300blk.

I run a 7.5" in 556.  Got a troy m7a1 kit, runs great, loud as hell but flaming pig helps a lot

That short of a barell reallly is 300 bo territory.  Might not even hit frag velocity at the muzzle.

I just love the look of the short barrels. This is a 5”.

They are pretty

Check out the SIG rattler in 300 blackout

Throw that on a preban  lower and your GTG.... even out to 100 or so yards
