Everything past the summary (pages 11-160) is blacked out.

Worked fine on my end. It is a Google drive file so make sure your browser is friendly. Firefox or Chrome usually. IE/Edge not so much.

OK, it comes through now. Must have been a temporary glitch.

I had a similar thing the other day. I opened a thumb drive and half my pictures were partially blacked out.

Thanks, Mark, for posting this. Even in the first couple pages I found a lot of info that confirmed my experiences when I borrowed ten M16A2's from a friend who was the Armorer for HHT, 307 Aviation Bde., for the Ft. Ord post rifle matches, as compared to the ten M16A1's from my own Arms room I prepared for the match.

Interesting that the Army completely skipped the M16 stating the M16A1 was developed from the independently developed AR15. Then again, the Army really hates it when you remind them that their primary rifle was originally adopted by the USAF. Biggest mistake the USAF ever made. Tried to go hi-tech and bungled it. Then the rest of the military tried to make a silk purse out of a sow's ear.

Semantics.

The M16 is an AR-15. The AR-15 was independently developed by Armalite and later Colt.

The M16A1 is developed from the AR-15, i.e., the addition of the forward assist.

We have several very early ARs at the Arsenal; Museum. These date back to the late fifties. note the pukey green plastic. Also note the duck billed flash suppressor, no fences around the mag release, no forward assist and of course no speed bump for the lefties.These have a 1-14 twist. .That aluminum contraption I am told is the very first, prototype forward assist. Don't know if that claim is true or not. When Gene Stoner saw it he had an excrement event and left Armalite in 1961. The AR at the bottom was the rifle that the Air Force adopted. Still no forward assist, or fences, but it has the birdcage flash suppressor.

The tapered-prong flash suppressor came between the duckbill and the birdcage.

The three prong suppressor collectors call the tapered three prong was on many of the XM16E1 marked rifles in US Army service and as late as the Mid 1970s some Infantry NCOs would change out the cage for a three prong when they could get away with it then remove it and carry it in their pocket to their next duty station....they were useful for opening crates with steel bands on them. also you could use them as a wire cutter in the same way ( two twisting in opposite directions or one , grab, stretch, and twist) or if in a hurry and in a bad place fork the wire and fire a round.

Yes, resulting in bent barrels. The reason that barrels got much heavier and why the birdcage was developed in the first place. Good info though.

Love that museum, went through a few times when dad was there on the Island.
