The 5 M16s of Vietnam (Colt 601, XM-16, XM16e1, M16a1, M16) 

The Colt 602 was NOT called “XM16” it was designated the Model 02. The ONLY “XM16” was the XM16E1 which was a Colt Model 603. Also, they introduced the full fence on late XM16E1’s there were also phosphate BCG’s on late XM16E1’s. There were 604’s that also had full fences

I carried almost every model of M16 the military has used. My favorites are the Air Force's Model 604 & GAU-5. Lightweight. Handy. No frills. Full Auto.

I just found your channel and really enjoy your content. Don’t be afraid to make longer videos. A lecture on 3 prong flash hider variations is a level of asmr I hope to find.

When I was in the Coast Guard, our M16A1's were from Navy surplus, I don't know if they were from Viet Nam era, but I was active 1988 to 1996, so I would not be surprised.🤷‍♂

Great Post Keep up the great work!

Yes, do more Vietnam war era stuff, never get enough info on "nam" weapons!

🇦🇺😎👍Great video Big Bad John. You’re very knowledgeable 🏁 🇺🇸

I was told the butsocks that were gray the soldiers would put oil on them to make them black.

The first one you showed is very close to being the transition M16 and it was the called the model 602.

“You don’t want to be here for 4 hours” I don’t? Sir, you underestimate my autism.

Always thought it was the M16, the M16A1 and the car15

Will you do M1 carbines used in Vietnam next?

Returned to the old outro?

Did you delete my comment about differences other than fencing between M16A1 receivers and A2/M4 pattern (buffer extension and pivot pin reinforcement)? I also suggested that mentioning more details differentiating A1 from A2 would be helpful (stock length, brass deflector, straight vs. tapered handguard retainer). There's nothing wrong with not exactly matching some historic pattern. I have an AR I really like that's A1 upper and furniture, 605 style barrel and flash hider, M4 lower, 22lr conversion BCG, and carry-handled mounted GLx 2x scope.

Can't stand to watch this. It's silly to me than a self proclaimed expert called the bolt carrier group a charging handle. What a fud
