  • man i just love the look of the carry handle and triangular handguard
  • I've always like the look of the classic M16A1 model. Its just so iconic and is definitely one of my favorite rifles.
  • You forgot that Eugene Stoner had specified a very specific process to be used for the chrome plating of the bolt and bolt carrier. Colt, in order to save money, went with their own plating process which resulted in the chrome plating of Colt guns flaking off under hard use and jamming the guns. This is why the bolt carriers and bolts were then only plated on the inside and parked on the outside.
  • This is honestly the most informative video I’ve seen the on early history of the M16 platform. Answered all my questions on M16 vs M16A1, 603 vs 604 etc. I live in Arlington and will definitely be stopping by the store to show my support. Thanks for the great video. Think I’ve watched the entire thing at least 5 times now.
  • We had the M16's that were coming back from Vietnam in Basic ('68) and AIT. They were always fouling out on the range. When I got to the Korean DMZ we had the M16A1, which I never had a problem with. The guys south of the Imjin still had M14's.
  • very good video i watched the complete I have a sp1 bought in 1979 in Muncie at mermorial drive off of highway 3 still have it thank you
  • Very few people realized it at the time and it has taken far too many decades for this fact to be fully understood: Eugene Stoner was an absolute GENIUS!

    I had a brand new M16A1 issued to me when I got to my permanent station in Germany in 1975. Harrington Richardson. Best 16 I ever shot. Accurate as heck. Very solid construction. No faults in my opinion. I thought it was an excellent rifle and I shot it well.
  • Great video. It answered every question I had about retro M16 rifles. Very educational. Now to head over to Brownells and build myself a clone correct retro rifle.

    Chris, Wow, such a knowledgeable and incredible effort you put in on such an interesting history of this gun. I grew up in Singapore in the 70's and as a school kid there I was infatuated with the M16. Now Im older I have a few AR15's myself and I just love them and especially their history. Thank you.
