There was one rifle that fits the CAR-15 "designation" that was actually used by your standard GI. As yes. CAR-15 encompasses a number of rifles considering it literally means Colt Automatic Rifle. Technically the M16A1 is a CAR-15 but shh.
There was also the Colt Model 605 carbine. More or less a cut down M16 rifle to give a barrel length of 15 inches.
There were two versions of it. The 605A and the 605B. The 605A had a forward assist and could fire in semi and automatic. The 605B had no forward assist (like the M16A1) but it could fire in Semi, Automatic and Burst fire. All 3. They also had the 3 pronged flash hider still. 605A came about being issued in 1963 and the 605B in 1966. Production numbers aren't a thing but it seems the 605B became the more common of the two.
I read stories of Vietnam vets and this rifle keeps popping up in all these stories. Usually in the hands of NCOs and low ranking officers. They were originally designed for helicopter troops but they were essentially put into an extended trial period indefinitely.
On Burst fire. I've been reliably informed that Burst fire with M16s doesn't work like how Burst fire works in other video games. Where you just click and it fires 3 bullets. Instead with Burst fire you still have to hold the trigger down for it to fire all three rounds. If you set it to Burst fire and just tap the trigger it will just fire 1 round. However another little quirk with that is that the next time you hold the trigger down it will fire only 2 rounds before it stops. There's some mechanical explanation for this I've since forgotten. But if you ever do the 605B do Burst fire right.
But yeah. None of that XM177 Colt commando BS. That was special forces only.
