[SHOT 2016] Troy GAU-5/A/A  Rifle

A student of the development of the M4, M4A1 and MK18 rifles knows that the lineage of these guns goes back to the Vietnam era with the Colt 629. The United States Army bought the Colt 629 and designated it the XM177E2. The United States Air Force bought the Colt 629 without the forward assist and designated it the GAU-5A/A. At SHOT this year, Troy is offering a limited edition replica of the GAU-5/A/A rifle.


The Colt GAU-5/A/A was carried during the Son Tay Raid (Operation Ivory Coast). The Son Tay Raid took place on November 21st, 1970. The mission was a joint operation between the Air Force and the United States Army Special Forces. The point of the mission was to rescue 61 prisoners of war being held at the Son Tay prison outside of Hanoi. Though the prisoners had been moved, the raid was still deemed a “success” due to the successful application of the tactics rehearsed before the raid and the coordination between the Air Force and the Army. During the raid, United States Special Forces took zero casualties and killed between 100 – 200 enemy soldiers. The 56 operators were on the ground for approximately 27 minutes.

If you want to purchase one of these rifles, you can pre-order one at MyServiceRifle.com. MyServiceRifle.com also has some fascinating information about Operation Ivory Coast as well as some neat pictures. Troy will donate $50 of reach rifle sale to The National League of POW/MIA Families.

Update 2/1/2016

I had a reader email me about a glitch in Troy’s pre-order system. If you pre-ordered one of these rifles and did not get an email response saying “Thank you for your interest …” the pre-order didn’t go through, or did not save. If that happened you will need to contact Troy or pre-order again.

Thank you Karl.

    Perfect to use to cap a woman in the head while she holds a child, endorsed by Lon Horiuchi himself! EABOD, Troy.

      I was under the impression that he had left Troy. Or did that whole fiasco just permanently leave a bad taste in your mouth?

      Jody Weis was terminated nearly as quickly as he was hired. Good on Troy for the fast response.

      Much better than HS Precision…

      But you have to do a bit of digging to find that they’d fired him when they should have been shouting it from the rooftops!

      It makes one hesitant to do business out of fear that the lesson they learned was “be more quiet when we make questionable hires.”

    GAU-5/A/As were still being used by Air Force cops up until they finally adopted the M4 around 2004ish. I carried one for a short time, I liked how compact and light it was and full auto instead of 3-round burst was fun too.

    I’ve got too many tacticooled out AR’s, so this is actually in line of what I want next.

    This looks horrible. They couldn’t even remove the fence from the lower receiver!? I’m pretty sure garage builders have built more accurate replicas of this rifle. What a waste of money. If you want a replica start with a nodak receiver. Don’t waste your $1,100 on a knock off.
