My replica XM177E2 project progress
I am working, slowly, on building a replica semi-auto XM177E2 (otherwise known as a Colt model 629).
I started with an Olympic Arms "Plinker", a very simple AR platform I got used from a friend. He had broken one of the upper reciever pin tabs, so he got a forged DPMS M16A2 upper to replace it (the OA Plinker does not have a forged reciever). It was missing the A2 sight components, so I got those. He kept the original barrel, which is good. It is a heavy barrel, with a .75 outside diameter all the way to the muzzle, with a "ban" style set screw flash hider. I junked that, and got a replica slip-over brake that is designed to look like the XM177 moderator, but threads to the standard 16" barrel. (The real XM177E2 had an 11.5" barrel, with a 4.5" moderator). I plan to have this barrel cut down and threaded to accept a true XM moderator with the grenade ring.
Next, I just got a Colt M16 A1 upper, with the correct sight, teardrop forward assist, and no brass deflector. It also has the correct A1 dust cover door.
I added an early non-ridged pistol grip, and more correct collapsible buttstock. It should be aluminum, with a 2-position buffer tube, but this is a polymer exact copy of the aluminum one (compare to a modern M4, which is different). Also added correct 6 hole carbine forend handguards, and topped it off with the correct nylon "seatbelt" type sling.
The front sight should not have a bayo lug, so that is correct. I finished it with dry film lubricant, the greay that is used on AR mags from the factory, to replicate early grey Colt anodizing.
All I have left is the barrel mod and moderator, find an aluminum buttstock/buffer tube, and eventually replace the lower with a Nodak Spud retro lower.
I'm almost there! Overall, a pretty cool rifle as my "workhorse" for the MUTT offroading ad tossing around, with almost no money to do it at this phase.

Prettttty close.
This is the one I have now....
OLD....Slabside Colt receiver, A2 upper. Barrel is 12" long, Heavy, Stainless steel, w/perm attached, 4" long, flash hider. Aluminum buttstock, Chrome plated bolt and carrier.
I have the Colt Parts to make it correct...as a Car 15. I will prob just use the parts I already have and by mixing them up, put another one together on a Bushmaster receiver that I have sitting on the shelf.

Re: My replica XM177E2 project progress
Cool! I like the slabside, but the later carbine I am building would have the later "full fence" lower much like the one I have now.
Do you have any pics of the whole rifle with flash hider?
Man, you have some cool stuff, mg man. Can I come visit you? I'll bring ammo.

That looks really cool, man . Now you've got me thinking about another "project" after I finish my L1A1 project. If OMGM's rifle had a slick side upper and A1 sights, it would have looked exactly like the Colt I had back in the mid 80s. On the flip side, that rifle was the biggest POS I've ever owned Still, pretty cool though.

Re: My replica XM177E2 project progress
Thanks, Matt. It will look a helluva lot better when I get the barrel cut and threaded. I am going to cut this barrel, I think, and have the moderator permanently attached so it is not a SBR, and add a grenade ring to the rear of this moderator.
Then the overall barrel length will be the legal 16", it is way too long now, at 18.25" in these pictures.
I really do like it. I want to do a retro M16 build next. Then I should be OK....

You can sink a lot of money into those projects but the end result is kind of rewarding making all the hassle worth it . I failed to post link to you in my last post (sorry) I assume that you probably already know about it. Here it is: http://98.196.65.94/retroblackrifle/index.html

Re: My replica XM177E2 project progress
Thanks, Matt...but yes, as you guessed, I am all over retroblackrifle.com already!
I used to collect WWII mausers, and specifically snipers. I was pretty into it, I have done a lot of research, and have some (minor) stuff published that I did for real new research. It was a passion, but just WAY too over the top expensive, I could not justify it anymore with the expense - and the level of fakery in that collecting realm.
I can build 5 retro AR rifles for the cost of a low grade sniper from that era. I used to look at a $5000 rifle as a near term goal. Bear in mind, the really nice originals that are 100% untouched are $20,000 guns in some cases. I traded one rifle from my collection for my M151A2. Now, I got rid of them all because of family financial needs, and have just a couple pieces left with sentimental value.
I am done with that. Collecting Vietnam militaria is my new passion...and I can live with it, realistically. Plus, it is a lot of fun, and I am truly fascinated by everything about that conflict. It feels more "close to home" for me now. I learn more every day, and love to hear from veterans, and being a combat vet myself, find it easier to ask and listen than before.
OK, enough about my life story.

OK...
I seem to be unable to post an image of the entire firearm as it keeps getting the end cut off.. So..

Damn. I keep forgetting that, despite the fact that I post huge pics. Thanks.
Nice carbine, OMGM, now that I see it.

Re: My replica XM177E2 project progress
Jeff: Awesome project. I was just looking at all the Colt AR15-M16 variants. I had no idea so many existed. I noticed one (633) with a 7” barrel and no moderator, can you imagine shooting that on a cold winter day. They say it was used by the DEA.
Good luck with your weapon.

You guys realize the original XM flash-hider/sound moderators are controlled by the ATF and have to be registered, don't you?

Re: My replica XM177E2 project progress
Yes, Bill, I know all about that. There are a lot of cosmetically correct replicas that look like a real one on the outside, but have none of the interior features.
