    How many of you guys/gals ever carried the Colt GAU5A? I carried one while at Aviano Air Base, Italy. Really enjoyed that rifle and very accurate.

    I carried one as a Security Police Flight Sergeant at Dyess AFB, Tx in
    the early '70s.

    I got curious one day and looked up what the GAU stood for.
    It's an Air Force supply designation that means Gun, Aircraft Unit.

    I found it odd they would group a personal weapon in with all the
    guns found on an aircraft?

    Over the years that little rifle has been called by several names.
    The US Army called it the XM-177 or Colt Commando.
    The civilian version was called the CAR-15.
    Colt called it the model 610 or Colt Commando.
    Today's most modern version is called the M-4.

    Yep, the AF is beyond goofy with adding their own 'twist' to common items and changing things just for the sake of change. What's our motto these days anyway? Hell, I'm sure it will change in 6 months anyway...

    Carried one for several years, on and off (CATM). Fun little guns, I often wanted to make a holster for one and carry it as a sidearm. :supergrin:

    If I remember correctly (it's been a looooong time), there were at least three variations of this weapon system listed in the Tech Order.

    - GAU-5/A (10.5 inch barrel, long flash suppressor/moderator)

    - GAU-5/A/A (11.5 inch barrel, long flash suppressor/moderator)

    - GUU-5P (14 inch skinny barrel, standard rifle flash suppressor)

    Me (well, most of me) with my GAU-5/A/A guard weapon, about 1986-ish:

    I'm getting that urge for a legal SBR again...

    They were neat guns. They still have them in inventory and are issued to the chopper crews at Malmstrom AFB MT even the ones that were deploying to Afganistan.

    I was issued and carried this GUU-5P in Iraq last year.

    This gets more and more interesting. It seems the Air Force is in it's own
    little world when it comes to naming it's personal weapons.

    They upgraded the GAU-5A to what the rest of the world knows as the M-4,
    but the Air Force calls it the GUU-5P instead of the more common designation
    of M-4.

    http://en.wikipedia.org/wiki/CAR-15

    "The United States Air Force has made ad hoc upgrades to its GAU-5/As and GAU-5A/As. The barrels and moderators were replaced with the longer 14.5-inch barrel with a 1-in-12 twist, but the weapons retained their original designations. With the change to M855 cartridges, they either received 1-in-7 twist barrel or complete upper receiver assembly replacements. The GAU-5/A or GAU-5A/A markings were removed and the weapons redesignated GUU-5/P. They also retain automatic fire instead of burst."

    "The new designation more accurately reflected the weapon's place in the U.S. Air Force Aerospace Equipment Type Designation System (AETDS). The weapons had initially been designated in the same format as aircraft guns, being placed in the GA category (GA designating an aircraft gun, with U meaning unit, representing a complete system and not part of a kit), followed by the /A suffix meaning the system was for aircraft. GUU is the "guns, miscellaneous personal equipment" category, and the /P suffix indicating personal equipment."

    Incorrect. Like Meeko posted, they are not at all the same.
    M4 = Flat Top upper
    M4 = Burst

    GUU5P = A2 upper
    GUU5P = Full Auto

    Our GUU5Ps did have M4 barrels, which were marked 1/7.

    The Air Force lists both the M4 and GUU5P in service and even lists the M4 as a suitable substitute for the GAU/GUU for qualification purposes.

    I will have to see if I can find some old photos of a GAU5A and myself. Loved those rifles and would love to own one now. Flight Leaders and Flight Sergeants, K9 and EST carried them at Aviano. I was an armorer and participated as OPFOR so I got to be issued one. I still miss my original M16 also. Had it dialed in.
     
  11. GAU5P parts mixmaster depot special. Full auto markings but with a burst cam installed . . . barrel was a pencil. Internals looked like hell.

    But she ran like a top and shot well. The magazines, however . . .

    Yep.

    Carried one at Ghedi AB, Italy (91-93) and Araxos AB Greece (89-91).

    Great little rifles.

    We still have the GUU here at the FE Warren armory, and are stilled issued out regularly.

    Brian, I was at Aviano 2005-2008.

    We'd completely gone over to the M4 by then from the M16, however a couple of our K9 sergeants had been issued GAU's and GUUs within recent memory (2004ish) during the switch.

    Was up at Creek D in 2007 and the opfor had them while we all had issued M4's.

    But hey they both work :)

    I wish I had some good pictures of the one I carried at Dyess AFB, Tx in the
    1970's.

    It's the weapon that convinced me how rugged and tough the M-16 family
    of weapons are.

    It had absolutely no finish left, it was beat and banged up almost beyond
    belief.

    But, it continued to fire and was accurate.

    I started carrying one version or another in 1976 as a K9 Handler at GFAFB when I worked security. First time I tried to qualify with one I couldn't figure out why I was hitting all over the place, until the extended flash suppressor fell off. Once it was tightened on the barrel it shot great. Also carried them in Germany, Korea and Wyoming while pushing a dog.

  19. I'd have loved to have seen the brass marks coating the inside of that one!

    CATM checked it, screwed it back on and let me keep on firing. Learned to check that thing everytime I took one out.
