    Colt CAR-15 XM177 E2

    Today as I was casually checking the main local website for gun sales, I saw an add for a Colt Commando. I immediately wrote to the seller, he called me and by luck was passing close to my house on his way to the mountain for the Easter weekend. He agreed to take the rifle along and stop by to show it to me.

    He said the barrel was replaced as the original was shot. The bolt was also replaced. Rifle is fully functional. Lots of external wear as can be expected with an old warhorse. Otherwise I really don’t know that much about this rifle.

    Wikipedia : In April 1967, the Army purchased 510 Colt 629 Commandos for use by troops assigned to the Military Assistance Command, Vietnam Studies and Observations Group (MACV-SOG), and designated them XM177E2. Delivery was completed by the end of September 1967. The Air Force adopted a similar model without the forward assist feature as the GAU-5A/A.

    Does that mean there were only 510 built in total and it dates the rifle between April and September of 1967. Or were more built later, after the initial order?

    The asking price was $ 3000, we agreed on $ 2700. For info I live in Switzerland. So the wait for the special license begins, should be 2-3 weeks.

    Pics (not the greatest as I did them in a rush) :



















    With its sibling (1972 M16A1)

    In 1969 our tank platoon got notified we would be getting a couple of XM177E2 to evaluate as a replacement for the M3A1 submachinegun. At the time almost everyone called them "CAR 15's", despite any official designation. Regardless, they were a hot commodity, as it turned out, the Battalion Commander and the S-3 intercepted them. That allowed to look cool going to and the chopper pad. Very few officers above Captain every got their boots muddy. Those of us who were in the field did see SOG and SF types with them. Saw a Stoner 63 machine gun once when we ran into some PBRs along the Vàm Cỏ Đông River south of Tay Ninh.

    I received the license and picked up the gun and the original barrel with the front sight this morning. No markings at all. The barrel was pretty corroded inside and pitted with weak grooves. I started cleaning it, hoping it would improve, but it just made the pitting shinier and more obvious.

    I will still install it in order to bring the gun back to its original condition. In any case it’s not meant as a precision rifle, and I will fire it very occasionally in full auto mode at short to medium distances.





    Seems to be a 10 inch barrel, not 11.5



    With the flat ring instead of the Delta / tapered ring.



    So I came to the conclusion that it is an XM 177 E2 lower with an XM 177 E1 upper. If these thing could talk.

    Some details :





    The large aperture sight seems to have been ground off, maybe for a faster target acquisition at short range.



    As a consequence, the small aperture sight falls backwards



    And the front sight was bottomed out in order to compensate



    ... with pliers ...







    The replacement barrel and front sight

    The original barrel appears to have no bayonet lug. The collapsible stock looks exactly like the hard-rubber coated metallic stock factory-mounted on my first AR-15, purchased in 1979 at retail for $399. Such stocks I have learned over the years are fairly scarce. The 6450 9mm carbines manufactured around 1990 or so had plastic collapsibles.

    Nice buy!

    That one saw some serious use. I wonder how it wound up in Europe?

    The front sight assembly looks like it was mounted with roll pins. I thought the original method was always solid tapered pins just like today.

    The aluminum collapsing stock was covered with a nylon coating.

    As always, we can only wonder at what stories it could tell.

    I have often wondered who made those aluminum stocks, doubting Colt did, but who knows?

    So my gunsmith installed the original barrel (well the barrel that came with the gun).

    He also test fired the gun, and the bad news is that the barrel is so shot, that the bullets keyhole even at 10 meters.



    On the other hand the full auto ran great with no hiccups.

    The other bad news is that the FSB on the replacement CMMG barrel was butchered in with 5 screws, two of them being totally seized. The smith did not want to drill the screws and risk damage something (I took care of that later) so he could not remove the old original flat ring









    Anyway here’s the rifle in it’s somewhat more original configuration


























    Now I need to find an 11.5’ 1:12 Colt barrel

    In the US Air Force I carried a GAU-5A/A as a duty weapon.
    In the early 1970's, while guarding SAC's (fully loaded) B-52 bombers.

    I miss that rifle.

    Thank you for those pictures.
    They bring back a lot of good memories.
