LGS has one.
Seems to be an accurate repro from what I saw. But I'm not sure I'd pay almost double what a Brownell's retro goes for.

still as of 7/2018 it’s still cheaper to build
While I'd love the rollmarks, I'd need more info an who actually built what parts and how. Otherwise might as well go with Brownell's which is at least a known quantity.

I can think of a lot guns I'd rather put $2300+ into.
An SP1 is much cheaper. Wish I could find one for partial trade down here.

I prefer the E1.

I saw Colts retro M16a1 build at a local store...Nice, gave me flashbacks, but they were asking $2500......Uh, no.

Yep, I will rather just have my Brownells for that price
I bought one for $1800, and I like it. I think $2500 is too high.

Where?
Shooting Surplus had one on like a 30% clearance a few months ago. I had been drinking bourbon and couldnt pass it up.
The cheapest Ive seen them lately is like 2100-2200.

I've noticed from Brownell's website that they appear to be continuing to upgrade theirs and make them more and more historically accurate - most noticeable was the lack of bayonet lug on their website, now. Plus they've got them on sale at least through Memorial Day.

This typically leads to many great firearm purchases! ;)

Indeed. My Brownell M16A1 was $899 on sale. Since I missed the 10% additional off sale by one day, Brownell gave me a $90 voucher. So my new M16A1 cost a bit over $800. Not the $2500 Colt wants. For $800 I'm good.57475
If I remember correctly the only colt thing about their M16A1 and 177e2s is the roll marks. Everything was contracted out to a company in Nevada
The dies for the lowers and uppers are colt owned and built off of the original ones, apparently. As for the rest of the gun US Ordnance makes it I think.
I build them for a lot less... I like the A1
On a side note regarding the XM177E2, what type of carbine buffer is run in it? Standard weight or heavier? The reason for asking is I am looking a building one myself....
I’m pretty sure it’s a regular carbine buffer.
I would maybe drop 1800 on a Colt marked and endorsed XM-177E2 but $2500 GTFOH
I would like to know more about Brownells making their XM-177 more accurate
The price of these retro Colts is more than I can afford, but it’s really great to see them recognize the popularity of their vintage rifles and offer them like this. It seems like better business sense than they’ve show in the past. I was talking about the Colt Python with a friend a couple years ago and discussing how they could have capitalized on the Python’s role in the Walking Dead and brought it back, but Colt didn’t seem to be interested.

My understanding is that the Heavy buffer came out of the XM4 program, along with the 'M4 feed ramps' as a means of addressing reliability issues with the XM177E2 (and subsequent shorty AR-15s). In fact, I believe the first heavy carbine buffer weights were developed for Colt's 9mm SMG - but these would be much too heavy for a 5.56mm carbine.
So a standard carbine buffer would be clone correct, but you would likely see benefits from using a Heavy or an H2 in it and there's no technical reason (that I'm aware of) not to.

Same way I feel about a 1:7 twist barrel on any A1 rifle or carbine XM177 clone.....why not? You can't see either the buffer or the barrel twist
Bartocci had a video claiming that with the carbine buffer (all steel weights, no tungsten weights) and non-M4 feed ramps, there were feeding issues. Said that Colt solved the problem in the XM4 with a combination of the M4 feed ramps and the addition of a tungsten weight, and those two things fixed the problem, but either modification alone would have solved the problem. I dunno one way or another if he is correct, just food for thought.

Brownells retros are not more accurate compared to the Colt offerings.
Chris Bartocci and I do not agree on this.
The Colt offering is worth it just for the lower alone. You can't get a more correct lower than the Colt offering.
I took my Colt retros and rebuilt them with correct late 1960s vintage parts.
I had an entire mint condition XM177E2 part set with real moderator awaiting just a project like this.
Also had a mint condition 1968 M16A1 kit that I used to rebuild mine.

How in the world did you score a mint condition moderator...pretty nice.?

Chris Bartocci reminds me of a man still madly in love with is ex-wife (Colt, he worked there 2 years) yet he still hates her guts (Colt for firing him).
I bought one of the US Ordnance built M16A1 retros, I absoloutely love it. No matter what Bartocci says.
Chris had good ideas at Colt but him and I don't agree on the retro authenticity project.

They are around if you spend some time looking at various ad boards.

I'm amazed something like that even is around. Did they stop making them like 40 years ago?
I’m lucky, I don’t even need to buy it. In my shooting club, there is exactly this model :)
If I wasn't in a "ban" State I would jump all over that!!

I have had two NOS Colt marked moderators sitting in the safe for probably 25 years.

So back in the 70's these things were in the wild....Colt was selling them I guess.
