Prototype mag. Note there is no channel for a magazine over-insertion hump to ride in on the lower.

But the upper would drop onto a standard lower produced today & run?  Takes an M-7 bayonet?

Presumably, if the magazine isn’t seated too low. Note that the over insertion hump channel extends to the upper receiver just slightly on 601 and later guns. This is probably more for cosmetics than anything, but could create a bit of a hang up.

Assuming that is not a problem and the gas port diameter is good, then, yes, I imagine it would run on a modern lower.

It’s probably been covered before, but anyone know the story of the green paint on some of the early magazines?

It is my impression that there is only one green mag, no bump 25rnds, usually pictured in one the prototype ARs #s1-4 at KAC the museum. I've not seen two pictured at a time that is.

#2 and #3 are not at KAC/ The IMT. Mr Knight only has the XAR, #1 and #4

And by referencing these pictures, they look like different magazines if you ask me:

Mag 1:

Attachment Attached File




Mag 2:




So it looks like two mags are swapped around, possibly between the XAR and #4. Here’s the most recent pic I’ve seen of #4 with a grey mag:

Wow, number 4 has has sling attachments in 3 separate places.  I didn't know that, or hadn't noticed before.   Thanks for those additional pictures Lieutenant.  Always a joy and never tire of viewing these old guns.  Now I'll go back to page 1 and spend an hour viewing all those old beautiful guns again.  Good viewing with my morning coffee.

Wish I had another double slabside receiver from Nodak.  I'd do a number 4 for sure.  From what I've read, they're not doing any more of those.  I guess there is a limited number of us PROTO freaks out their is why.  Oh well, I'm still enjoying the journey anyhow.

No option for all the above.

They're like potato chips, you can't have just one.

Yep, #4 is a very unique rifle and is my favorite of the prototypes.

And yes, all of the above are very awesome rifles, but some are cooler than the other lol.

Excuse my ignorance, what is the upside down trigger looking thing in carry handle?

That is the charging handle that was used before the commonly used triangle variety.  It was found to be too fragile, and it was hard to use with gloved or dirty hands.  It also tended to get way too hot under continuous use

Those are the original 25 round straight box magazines. They were not reliable and were replaced with the 20 round magazines that are still being manufactured today. 30 round curved magazines didn't arrive on scene until around 1967.

So... apparently, 000002 and 000003 were confiscated, along with several other prototype weapons, by the State of Georgia several years ago.

PDF of the complaint

This was 2017 so, I wonder how the case has progressed? It'd be a travesty if the commies in Fulton county destroyed these.

Was aware of this as well but at the request of another member who gave me the info, I did not put it on the web. Yes, the GBI has those weapons as far as I am aware at the moment.

I would have to disagree with the claims made by the appraiser, as he makes it sound as if there were only 5 prototypes made.

I stumbled across it doing a search. If someone doesn’t want the info posted here then I’d be happy to remove it.

I think the info is fine being there... It's been long enough and the facts are known amongst many, just hasn't been overtly stated until now.

This is the most interesting and informative thread I have ever seen. Thanks OP. Also the best thing to ever come out of Hollywood. I’ll be reading this over and over. Needs a tack.

I’m planning to get started on an A2 retro build and am a complete newb at retro stuff.  I have already been warned about how expensive it can be to build one.

I think the info also belongs in in its own thread set up for discussion. (Did you know that Georgia taxes business inventory?)

A mention belongs here buy discussion of it seems off topic.

Its only gone up since I started, and I was late to the game.  You're welcome though!

The thread is saved in the "information links" thread at the top of the forum, but I also wish it was tacked on the front page myself. I might be a bit biased, however.

Info about #18's modified barrels added. Potentially was the first to have the thicker profile seen on #3. 22 September 1958 could be the point when the thicker barrel and flash hider were first seen by the U.S. military.
