The 11.5 on page 354 has a teardrop style FA, the photo quality is just poor and it doesn't stand out well.
The gun on page 355 actually has an A1 profile lower, despite saying "M16A2" on it, which was a common thing for 733s, but usually the *earlier* production ones with A1 or C7 style uppers. 733s with A2 uppers are later production guns generally.
Also back on page 354, it's interesting to note that the 14.5" carbine, labled a 723, has an A2 upper. I thought 723s pretty consistently had A1 or C7 style uppers. It could also be a mislabeled very early production 727 though, which allegedly briefly could be had with pencil barrels before going to the stepped "M4" style.
So basically this is all just more evidence that consistency in Colt's 700-series carbines was a real shitshow.
There isn't any mystery here.
That gun appears to be all factory. It should have a 2 position buffer tube.
The stock appears to be still staked. Look at the left side stake. The black ink edge goes across the lockring, and backplate, and lower edge of the black ink is not interrupted.
Near all Colt 700 series 14.5" and 11.5" guns are marked M16A2.
Several early 733/723 were built without a brass deflector and built with the black vinyl coated metal stock.
Some were built with bayonet lugs, but not many.

Thanks, Scott, you nailed it and cleared a lot of things up . Someone else pointed to the markings, but I could not see it because it is so slight and indistinct. I had to look very hard and use my Iphone to take a picture and enlarge it. It looks like a Colt marking. Below is a picture:

On a different note, if I were to buy a select fire gun that is listed on the form as having a 11.5" barrel, what NFA paperwork would I have to do to be able to legally use a shorter barreled upper with it?
On a similar note, I have an SBR lower that is registered as having a 10.3" upper. What changes and paperwork do I need to do to enable me to use a shorter barreled upper?
thanks
None. The BATF only needs to be notified if you permanently change barrel lengths. If you do make a permanent change, I believe all that's needed is a letter of notification. It's legal to swap uppers of any length to your lowers without any kind of notification.
