I have a Stag Arms 16" upper with a regular front sight gas block and I want to be able to mount a bayonet on it. Just because.

It is my understanding that the distance from the gas port to the muzzle is longer on a commercial 16" barrel than a 20" M16 or a 14.5" M4.

Is that correct or is there a bayonet that works?

Thank you.

Sorry that this isn't much help, I don't know much about bayonets. But I can tell you that my friend bought a S&W bayonet and we tried mounting it on my gun and it didn't fit very well. Pretty uneven. It was a 16 inch with a normal front sight

A bayonet will fit properly on these combos: 14.5" barrel w/ carbine gas, 16" barrel w/ mid length gas and 20" barrel with rifle length gas.

And done. There are modified bayonets, but a regular one will not work.

You can mount a bayonet on the 16" with carbine length gas system but only about 3 or 4 inches of blade stick out beyond the muzzle. Looks pretty dumb.

I guess I need a 16" upper with a mid-length tube.

Thanks your Highness!

AFAIK there are two ways to make a bayonet fit correctly on a 16" carbine: (1) get one of the old General Cutlery bayonets with the extended handle, which was designed for 16 inch carbines, or (2) use a clamp-on bayonet lug ahead of the FSB.

Not mine but this pic from quarterbore shows how a 16" with a carbine gas system does not properly fit a M7 or any standard bayonet

This pic from m9bayonet.com shows how a 14.5" M4 barrel carbine gas system properly fits a M9 bayonet

My 16" midlength gas system carbine fits fine with my M7 and USMC OKC-3S bayonets

My 20" USGI M16A2 Colt rifle gas system barrel on top fits my USMC OKC-3S bayonet and below is my 16" carbine gas system LMT with an extended handle M7 bayonet which are very hard to find now

Here's another sample of an available extended bayonet handle which are Colt marked Eickhorn Solingen bayonet from PreBanArms.com ($219.95) pic by member _DR (see archive thread link below for ref.)

Also as said before a barrel bayonet lug adapter could be clamped on the barrel at front of the front sight of a 16" carbine gas barrel.
