I'm trying to figure out which one I want to build. At first, I thought I wanted a GAU, because NONE of my AR's are slick sided, and I figured that would be a neat departure.



But then I realize that the US Army used the M177E2, and for Army pride, I was thinking I should do the MX177.




Help me out here. These are tough decisions. First world problems.

E2 if you're a MACV-SOG aficionado, if not then.. E1 or GAU.

Where do you guys get the vinyl acetate stock and tube set? Also are there any vendors for slab lowers other than nodak spud?

Unless you can source an original Colt vinyl acetate aluminum stock for a decent price, Essential Arms is the place to go for the stock body. Nodak Spud has the correct 2-position buffer tubes. You will need the old style castle nut. Nodak Spud used to have them on their website, but they are not there now. You could probably call them and ask about it.

Then it wouldn't be an XM177.




I'm not doing a E1 because you cannot get a proper moderator, which you'd want on a 10" barrel to make sure you have reliable function. So it's going to be an E2 if that's the route I go.




I'm pretty sure I need to do the XM177 because of being former Army.

XM177 is slick side upper with 10" barrel

XM177E1 is forward assist upper with 10" barrel

XM177E2 is forward assist upper with 11.5" barrel


 Sure you can, depends on how much you want to $pend...

Um you might want to talk to Hkiller his runs like a top. I don't think it's a real moderator but a brick. It's E1. Here is a pic of his.

I did an XM177E2, as much as I like the XM177. To me it doesn't justify the extra $200.00 tax stamp to move the fake moderator two to three inches down.

You mentioned the army used the xm177. I never hear about what the marines used. What did they use primarily? I'm guessing just xm16e1's and m16a1's?

That's true, but it's not like the XM177 didn't do anything the entire conflict. The XM177 was used by SOG and therefore, used quite a bit and used for alot of secret missions.

I'm currently on the final stages of an XM177E2 build. The GAUs are definitely unique in the long history of the AR15/M16/M4 family.

This site is costing me a lot of money.  First the 607 parts, and now two more, maybe three, if the Colt M16A1 is hard to come by or super expensive.
I have been watching for normark singlepoint scopes on ebay.  Who knows how long that will take.

As far as I know the XM177 was only an air force carbine.  The USAF didn't believe in the need for a forward assist so they had the slick side upper with the 10" barrel (XM177) and designated it as the GAU-5/A.
The XM177E1 was the forward assist army version and was stamped COMMANDO.  It was identical to the GAU-5/A except for the forward assist.  The E2 was army issue and used the 11.5" bbl.  From what I've read on this, many E1s were rebarrelled and armorers over stamped the 1 with a 2.

Of course over time carbines were repaired and parts mixed up a bit so there's some confusion, especially with the USAF guns.  They have a few different designations over time as parts were swapped out as policies changed over the years.

Anyway, this is what I believe to be correct.  If I'm wrong please advise.

XM177 (R610) and XM177E1 (R609) are the same except for the forward assist.

XM177E2 (R629) and GAU-5A (R630) are the same except for the forward assist.

Except for the Son Tay raid, if there's no forward assist, it's USAF only.

The Air Force started assigning USAF personnel (forward Air Controllers) imbedded in Army units.
So a GAU mixed in your collection would not be out of place.
