I bought a Wilson Combat "intermediate" gas barrel for my 308 build thinking they simply meant midlength. Realized my mistake after my midlength gas tube came up short.
I did not know this length was a thing.

No, intermediate is not midlength. Yes, it's standardized (1.50" shorter than rifle), although less common.

An intermediate system shouldn't give me any issues in a 16" .308 build right? Slightly softer shooting compared to mid?

Guess you'll have to shoot it and find out.
Rifle gas 18's are common.

Shouldn't be any issues if done right.  There is another length, which is the ArmaLite, AR-10 Rifle Length, is about 3/16 inches longer than the standard AR15/everybody elks .308 AR type rifle, rifle length.  The ArmaLite's AR-10 bolt carrier comes with a gas key about a 16th of an inch closer to the front of the bolt carrier.  Gas tube should end in the upper receiver at, or just to the rear of half way past the cutout for the cam pin in the top of the upper receiver.

It's all together except for the tube and adjustable gas block. Looks amazing!

Is there not a length betweeen carbine and pistol?

And there is another pistol length.

Also, noveskie uses one in their leonidas that is about an inch shorter than middy

White Oak makes a two and a three inch longer than standard rifle length gas tube.  Mostly for long barreled (24-26 inch) space guns.  and as for the shorty's Im sure there are a few proprietary length as well.

i would think it would be pretty good on a 16" 308. The KAC length was supposedly originally intended/optimized for a 16" 308, and intermediate is just a little longer.

The Intermediate gas system on your 16” barrel is pretty much the longest system that will provide reliable functioning.

The distance past the gas port needs to be around 3” or so to allow enough dwell time without underpowering the system.  This is usually something people run into with a carbine gas system on an ultrashort barrel, but the point is the same.

It should be both “softer” and give you a lower cyclic rate of fire.  Whether it is ‘too soft” will depend on your buffer and spring, as well as the ammunition you choose.

In for results...

The "Intermediate" length as set up and named by Vltor is 1.50 inches shorter than rifle. If someone is making something else, they need to give it some other name.

308's get confusing because if they want to use a standard handguard, the gas tube itself has to be longer than a 5.56 gas tube, ie, the Armalite gas tubes. But since there are no Intermediate handguards, I would think that it would be the same.

Wilson Combat uses a 13.25" length for Intermediate. Had to order another gas tube. My third.

Sounds like it's a KAC length, or just something they invented, either way they need to call it something else besides "Intermediate" which it isn't.
