Alrighty,
  I couldn't think of a better title but, assuming I'm not going the SBR route, is there anything a carbine gas system can do that a middie can't (besides use USGI gas tubes)?  I don't have a middie yet, but from everything I've been reading, they're the cat's ass and seem to be an established "evolution" of AR design.  So what say you?  With the exception of SBR's, is the middie THE way to go for a 16" carbine?

Yes, go mid.

Unless you're going shorter than 16" for a barrel, I cant think of a reason to not go mid.

I love the smoother functioning so much Im probably going to convert most of my ARs.

Middie all the way. Much smoother and more reliable.

Yeah, I was thinking of selling my LMT 16" M4 upper to help fund a Denny's Operator/Stealth upper

I have both 16" LMT M4 CAR and Operator middy on my Colt 6721 carbine and I prefer to use my middy most of the time because of the smoother action.

My next 16" carbine project will be also a middy.

My CMMG 14.5 middy runs great.

It seems to me it has the lightest recoil impulse out of all of them.  Which you'd think the rifle would but not in my experience.  Even though I like the way the carbine looks better, the middy has been said by many I trust to be the best.

I can't tell the difference in impulse between a middy and a rifle, but a carbine has a much harsher "kick" to it than the middy IMO.

excuse the dumb question guys. but what's the difference between both besides the handguard length?

the mid length gas system is longer than the carbine gas system.

ETA:  The longer length of the mid length system reduces the pressure of the gas impinging on the BCG.

The gas tube is a bit longer on the mid length, so you get a different amount of pressure in the gas tube.  The longer the distance away from the chamber, the lower the pressure in the gas tube, as the pressure is contantly decreasing from the moment of powder igition, and longer = later.

The lower pressure tends to make the cycling more relible, as the AR15 series was orginally designed for a 20 inch bbl system.  It also puts less heat back into the reciever.

The only downside to the mid is a bit more weight.  It's the way to go with a 16" bbl.

Valid points. But the most important part of the mid-length profie:

BEE TO THE AY TO THE WHY TO THE OH TO THE ENN TO THE EE TO THE TEE, BABY!

That's right! Fix motherfucking bayonets! My 16" has a lug, but I can't fix my bayonet due to the barrel length, my 20" is a post-ban, so I can't fix my bayonet. The mid-lentgh profile gives you the light weight and maneuverability (and uh, NFA compliant legality) of a short carbine, but retains the ability to fix your bayonet.

If you've never bayonet charged a jackrabbit, you haven't lived.

Sadly, I need to fix my 18" sword bayonet to my No.1 Mk.3 if I'm ever to bayonet charge. I never thought I'd say that I missed my SKS.
