A while back a friend of mine allowed me to not only hold, but to take apart Armalite Prototyoe AR15 serial number 3. I have posted some of the photos before, but for one reason or another, I have never posted them all at the same time, so here you go. I hope you have as much fun looking at them as I did taking them  I am also including some derailed photos of prototype #2. It will probabky take me about an hour to load all of the photos.

I found the fcg interesting and that they didn't use a C clip on the dust cover rod. The whole rifle is very interesting, but I never realized those two areas differed from future ar15's so much. |

Very interesting "basket weave" pattern on the stock!
Attached File Also interesting to note the length of the 25 round magazine at around 5.25". It is as long as a Lancer or Magpul 20 round magazine! I wonder how long brownell's new 25 round magazine is? |

Can't wait to get mine from you guys. Shipped yesterday! Also, can anybody explain the FCG setup? |

In answer to questions, I did not photograpgh the bolt groups because they both appeared identical to standard chrome 601 bolt groups. Quoted:

I gotta know, how was the BHO retained in the lower? Because the pics look like we cut it the same way I could only find one place that sold connex pins to the general public but they only sold in boxes of 100 and they closed last year.

Quoted: Likely the improved carriers. The originals were slabside, like mini AR-10 carriers. Should have still had longer gas keys than 601/modern carriers though. |

Quoted:
No, the gas keys were the same size as 601 keys, otherwise I would have photographed them. Why do you think they should be longer? 
Notice how on each carrier, even on the picture of #3 from TBR in the middle there (a bit hard to see), the gas key extends to the rear of the bolt lugs of the unlocked bolt. Notice how on the 601 carrier, it doesn't even extend past the carrier face. The early AR-10s are configured in a similar fashion. |

Either I missed the difference, or they had been "changed out" to regular 601 bolt groups Speaking of that, what became of the owner and the guns? Haven't seen them at shows for a year or two now, their website is gone, and their social media has been abandoned. |
