Have bought a number of things from them and they are GTG.  Currently have a Lebanese LMT rifle for sale that I am lusting after, but it's expensive, an SBR and I already have way more AR's than I need, so it's a pass.

Thoroughbred Armament is good to go.  Ordered from them many times.

I've spend thousands with them:  MK13 Kit (should have bought more), I don't know how many KAC RAS, BCs, Surefire MILSURP lights, etc.  The absolutely take advantage of free USPS packing materials . . . and they're from KY, but otherwise nothing to complain about

Except that the profile is different and they're not cut down.

What's the gas port size of the barrels they are selling? I emailed them, but no one responded. The one I ordered from Arms Unlimited had a 0.074" gas port.

Should be 0.070" across the board.

AU and their "Commado Heavy Barrels" with 0.074" GP diameter was fuckery.

Not was fuckery, is fuckery. I purchased one last week from AU, so they're still selling one's with a large port. Blems maybe? AU responded that Colt says that is the spec..

I agree. Everything I had read and researched led me to believe they're supposed to be around 0.070". That's why I was hoping someone who had purchased one from Thoroughbred Armament could verify the ones they're selling have a 0.070" gas port size. They don't seem to like responding to emails or inquiries. I guess if no one can give me a definitive answer, I'll have to go with the Centurion Arms FBI barrel when I find one in stock.

What does your GP diameter measure, out of curiosity?


Try them on social media? I've had good luck on IG, but it has been awhile.

The gas port pin gauges at 0.074".

I don't have an IG account, so I can't contact them through there. If they can't respond through their normal channels, then I'm not sure I want to order anything from them anyways. If they can't respond to emails or inquiries via their website, I don't have any confidence that I'd be able to get a hold of them if something was wrong with an order or item that would need to be returned or exchanged.

I guess I'll have to keep searching for a place that sells them that can answer questions and verify GP size.

Curious,  I wonder if these are indeed remaining stock from 2019 or if they are another batch.

As for the contact hurdles, I fully understand.  Best of luck.

The Colt sticker on the box has 8/1/25 printed on it. I don't know if that's when it was made or boxed. The barrel doesn't have a date stamped into it. So, who knows.

I was hoping someone who had purchased from Thoroughbred recently, would chime in and say what their GP size is. If for nothing else, for curiosity at this point. I guess I may have to go the BRT gas tube route.

Thanks.

I bought one from them a few weeks ago.  I'm traveling for work but I should be home this weekend.  I don't have a complete set of pin gauges but i believe I have .070, .072, and .075, so I'll see what does/does not fit and report back.

That would be great. Thanks

Ok, just did a quick check with the pin gages.

.070 dropped right in, good amount of wiggle.
.072 dropped in, less wiggle, but still there.
.075 did not fit.

So it's bigger than .072, but smaller than .075.  Most likely .074 as the other barrels.  I ordered this on 8/16 when they popped back up in stock.

Thanks, I appreciate you taking the time to do that.

It looks like 0.074" is the gas port size they are coming with. The part number that both AU and Thoroughbred seem to be selling is 402251. I wonder if the ones that came with the smaller gas port have a different part number. It would be a good thing to know.

Just figured I'd add an update.  I finally received the 11.5" standard profile barrel I've had on order from Brownells since last summer (6933 commando stripped barrel P/N 401065).  I checked the gas port and it's the same as the 11.5" heavy barrel I bought from AU.

.072" fits
.075" does not fit

So I figure this barrel is .074" also.

It's pretty fucking sad that the only vendor that currently offers these that "openly " advertises the GP diameter is Charlie's.


Why there are 2 variations of port diameter is beyond me.
