Multi-caliber MG?

[Revopop]

Just wondering about this, if I were to buy a transferable M-16 in 5.56mm, could I also get a 9mm upper and mag block for it? Would there be extra paperwork involved?

Machine gun trumps all. You can make it an SBR and change out the calibers

I heard just today that an M-16 shooting 9mm is very hard on the lower.

How so?

Yes you can get a 9mm block for the lower, buffer, upper, and mags and your good to go. No additional paperwork required.

Supposedly the blowback operation of the 9mm upper is harder on the FCG, which may cause the FCG holes to "egg" out. I beleive this is the reason why there was a need to ramp 9mm carriers...to ease the impact of the carrier on the hammer.

That's accurate about 9mm being hard on pins. Ramped bolts solve this problem.

So having the ramped bolt means no stress then on the lower?

It means less stress on the lower, yes.

I've heard also that anti-walk pins are must on a 9mm M-16 for the same reason.

Now I've just gotta start saving my nickels. If I give up cigarettes, it'll only take me 8 years or so to get an M-16 with the money I've saved! I wonder how much more they'll cost in 8 years, though...

I've got a stack of Small Arms Review and Machine Gun News magazines from the mid-late 90's that are full of tear jerking classified ads in the back. I'm still trying to talk my dad into buying a Thompson or two with my inheritance!!! then at least we can enjoy his money together!!

i have the anti walk pins so are you suggesting that i get the 9mm ramped for my m16 as well?

 

[VUPDblue]

Your bolt is already ramped.
