I was stationed at Hurlburt Fld (AF Special Operations) in the late 70's. We had several different lengths and it is really hard to say what was the most common. I know of one that is 14"-15" (I didn't measure it) that I know for a fact was an issue barrel for the XM177 series (GAU-5). This known barrel also originally had the grenade launcher ring and moderator on it.
As for value...I am curious also.

I agree the barrel had possibly been changed. It may have come back fro Vietnam and been rebuilt. Or it could have just been another of our "specialty made" guns. The barrel has " C MP CHROME BORE" and has the 6 hole "CAR Style" handgaurds. The front sight has a "C" on it and also has the bayonet lug.
For some reason I seem to think most of ours had this length barrel. Granted we had shorter ones too.
AS a side note,
I do remember one day being given a Vietnam captured Russian SVD Sniper rifle thaty was said to be the first one captured and brought in to the US. I took it to the range and was amazed at how accurate it was for such an ungainly looking rifle.
That must have been an odd duck, a 14.5" barrel with the moderator on it. That would bring the total length to around 18.5" - 19" or so. The 14.5" barrel originally supplied on the model 653 wouldn't need the moderator for function. Some kook armourer must have thrown that together.
Also note the 14.5" barrel replaced the 11.5" version as it wasn't as tempermental relative to functioning and had better efficacy with the M193 round, thus at the time making the 11.5" barrel obsolete in most circles.
As far as original Colt's available in 10" or 11.5" lengths, few and far between, are highly collectible, and stashed away in collections. Most of the guys I know that have them won't part with them for anything. So be careful when an 'authentic' example shows up, as many have been faked often by cutting down longer barrels and remarking them. There was a time about 20 years ago when it was the 'in thing' to have, a shorty. The problem was there were not enough real examples available. So, what do guys do? They make 'em. I would guess to find a real serviceable Colt 10" barrel in this day and age next to impossible.
Remember the 11.5" version hasn't been used in 30+ years, at least haven't been manufactured. The 10" version even longer. This is of course referencing those in original 1/12 twist configuration.
By the way, the moderators did not have baffels in the traditional sense, but had chambers. The ATF determined the moderators reduced sound signature by 1.5db, thereby ruling it a 'suppressor' in their convoluted opinion.
