I think we just got distracted. I suspect it is for new builds. Also a rainy day. I'm not wearing out BCG's anytime soon with the lack of ammunition these days.

Thanks. That what I think too. My own BCG would not wear out in my life time.
I looked up the serial number from the M16 I used in basic training:
4,786,107 - number 98 in the rack - we were told to memorize it, I did, and I've never forgotten it, but I digress.
That M16A1 rifle was manufactured in 1971. I went to basic training in August-October of 1989.
Obviously I can't tell you the service history of that rifle. I can't tell you if it was ever rebuilt, used a different upper, barrel, etc. However, the fact remains that the rifle I shot over and over again, and that I cleaned (likely incorrectly) over and over again, was in it's 18th year of service on a basic training installation.
Who knows how many rounds it fired, or how many basic trainees fired it before me? With that in mind, it leads me to believe that an AR pattern rifle is probably pretty danged hard to wear out.
They are out there. They are not cheap. I just ordered 4 for a few 308 builds. The one stop shop is gone for sure..

Which did you order for those 308 builds?
Nothing wrong with NiB BCG's, but to me it's a solution looking for a problem.
The only time I ever saw a gas key come lose was also on a NiB BCG. if the threads of the carrier are also NiB or Nitride coated, don't you think the lower coefficient of friction poses a potential issue?
And to answer a previous question - new builds and sometimes a spare or two. A good bolt will take a long, long time to wear out. Unless you are putting a thousand rounds per month through your AR, it'll be a good while. A good BCG can also be rebuilt a few times with a new extractor, springs, etc.
I've had a lot of friends want to put together an AR this past year, either because they couldn't find a complete one or they wanted to do something alittle more unique. In all cases they brought their own lowers, but I've helped a good deal of them with parts selection.

Thank you, 2 inbound.
If anyone is looking to stock up on LPK's for future builds, global ordinance is having a sale on CMMG kits.

Referring back to my post above how my basic training M16 was manufactured 18 years before I put my hands on it, there's no telling how many thousands of rounds that rifle handled. I know that in my time in Basic Training, In one week during our main BRM (Basic Rifle Marksmanship) period, I probably fired close to 1,000 rounds, and then fired a bunch of blank rounds during bivouacs doing various ambushes and staged firefights with other platoons.
So lets say hypothetically that rifle was in continuous use as a basic training rifle from 1971 through 1989 - 18 years.
To round things off, let's say that every basic trainee fires 1000 rounds during their 2 months of basic training. There are 6 training cycles per year, so that's 6000 rounds times 18 years = 108,000 rounds.
Clearly that rifle never saw THAT kind of use, but it was plenty worn out by the time I got it - it rattled like crazy and the takedown pins would push free with almost no effort at all. Undoubtedly it had been rebuilt a number of times before I saw it.
Thanks man. Picked up a couple for backups, and also found a few spare parts for my berettas to boot
Good deal and great price!
I received my RCA BCG today. I have to say it has one of the smoothest finishes and machining work I have ever seen on a BCG. I can see why Noveske uses them.

What’s the general consensus on Gunlabs bcg? I didn’t find anything much negative, so I’m assuming at least decent.

...like, is it chrome lined?
I don't know that i've ever seen a chrome lined Nitride carrier or if that is even a thing.

My biggest concern with most BCGs available right now is the 9310 bolt. C158 is a better option.
I haven't seen nitriding with chrome.
I haven't seen nitriding with chrome.
That debate has been raging for years but from everything I've seen they are equivalent.
