XM177/Colt Commando/Car15

Here is how to cut, crown, and thread a barrel with nothing but hand tools. Making an XM177-E2 by cutting the barrel and pinning and welding a muzzle brake at 16 1/2 inches. Getting this ready to sell, Colt scope is original..

I sent this link to a buddy in 7th GRP. We’ll see if he can resist. I know he’s wanting to build one and has the scope already.

Thank you for showing the technique, the gun looks great.

Nice!! Aluminum buttstock or poly?

I did a build with an original aluminum stock. I have no idea what the rubberized coating was on that stock.... but it was impossible to remove!

Which was necessary for the particular build...

This one has a generic plastic stock as it is only sort of an XM-177 and will be selling it. It has an A2 upper with the adjustable sight.. I am building a GAU-5/A with an aluminum butt and have a Troy industries XM177 with the aluminum butt.

My personalized XM-177

Cold War Roumanian AK. We all had one of these CIA procured AK's for deniability and battlefield re-supply of ammo.

Pretty cool. I built a qausi clone one a while back. Neat guns but I left out a few details. No pic of that one sadly.

later, I built a 723 clone ish gun. Didn’t have the cool dive light pipe clamped to the bottom, but had the correct style Aimpoint.

@buffalowinter
Did you ever see/know anyone who used a fixed-stock lower with a carbine upper kinda like this configuration?

r.tenorio671 · Oct 19, 2021

...nicely done

...the XM177's and GAU's were the ones that started me on this never-ending foray...

There is a very early model predecessor to the CAR-15 called the Colt 607. It used a short buttstock, but it was collapsible. I am currently making one of these. It saw some use in Vietnam circa 1965.

sirhrmechanic · Oct 19, 2021

If I recall correctly they also had a port firing weapon for use in M113’s and tanks. Goofy little thing. Cheers Sirhr

Very nice but real operators used the Swedish K!

The M231 Firing Port Weapon?

Sure is goofy-looking. Seems they came with removable wire stocks "just in case" they needed to be used as actual assault rifles but I can't imagine that worked out very well in practice.

@buffalowinter Yeah the 607 was why I put the short triangle handguards on my upper despite it being more-or-less a XM177. It's mated to a lookalike of the XM16E1 lower in the photo; I have a matching E1 style upper to go with it as well. But I meant specifically if you'd seen any combos of a carbine upper of any type mated to a A1-fixed-stock M16 lower. I'm sure I've seen a couple photos of MACV/SOG and the like in absolutely-not-Thailand-or-Cambodia with them somewhere or another. I think the reasoning was the rifle stock was more comfortable versus the metal carbine one, or the heavier rifle buffer helped with better control going full-auto, or something along those lines.

milprileb · Oct 19, 2021

SF guys soon learned the Swedish K was worthless in a fire fight. Let me frame this : 9mm vs 762x39. I am sure that translates 5x5. The Swedish K had a KF * factor of 10 for Rear Echelon types, really wasn't bad for a chopper pilot if he could scrounge one and just the thing to toss in your pilot helmet bag on an in country R&R. Great Smg but clearly limited use weapon.

I carried a XM177E1 in Viet Nam and it was totally reliable. Saw no reason to turn it in for a XM117E2. In mid 80's , we had XM177E2's in a SMU that I was in.

Yes, I knew a guy in CCN who carried a XM177E2...the lower was a standard M16A1 rifle and upper was XM177E2. He preferred the solid M16 stock. Worked for him.

* Kool F..ker.

I was joking about the Swedish K hype.
It died rapidly when the XM 177 versions appeared.

The port firing weapon was a bear. It only shot in full auto, didn’t have ANY sights and the cyclic rate was stupid fast. They are fun to shoot though. If you can control one when it is not secured in a port. I have some video of us shooting them in Iraq way back in the day.

My A-1 rifle stock has a rubberized sling attachment with intact rubber coating. Amazing durability.

My cousin was a Bradley driver in Desert Storm. I'll have to ask him if he ever tried the PFW.

We took a bunch out for a fam fire in Iraq around late 05 early 06. We were stuck on a small island next to the Euphrates and decided it would be a good time to get everyone fresh on what was/could be available to them if shit hit the fan. What a monster, but very glad I got to play with one. We got into a 9 ish hour skirmish with the Mahdi militia and I believe some of the M2A3s there that day had theirs in the port. Whether or not they used them I don’t know.

I’m guessing if they had them, they warmed them up.

Everything else got to play, M1A SEPs got to launch canister rounds at RPG teams as well. It was like GI Joe got turned guns free for the day haha

I miss my Model K! Thing was awesome to shoot! Very controllable!

Take the retaining clip out of the mag well and take the mag well off and you can use 50rd Suomi sticks and 71rd Suomi drums in it also!

Later, Frank

You may be cool… but you will never be Charlton Heston driving around an empty Los Angeles in a Caddie convertible Wearing a
Safari jacket and aviators, shooting zombies with a Swedish K…. Unless you are @buffalowinter. Then you are, in fact, cooler.

Minor quibble number 1...CH is using a S&W Model 76...and yes I have one (well, an MK760 full auto nfa registered).

Minor quibble number 2...His 1918A2 is cooler...and yes, I have one (well, the high grade Colt 1918 in custom case). And, I have a Smoking Jacket but no puffy shirt.

And, totally unrelated other than the cool part...ran across this picture of my Team and the Incursore running around the Dolomites with the Beretta BM12. Tension was high as two soldiers had been murdered the week before by separatist terrorists.

sirhrmechanic · Oct 27, 2021

See? I was right.

And I knew it was a Smith 76. But they are all Swedish K’s in my book!
