You get what you can get your hands on since not all of them are readily available here in Canada.
As long as it has good staking at the gas key it should be fine.

While many people seem to think they're all about the same, the truth is that there are a lot of small differences (company to company).
We sell LMT, Spikes and RRA... used to sell DD as well.
If it was my gun I'd choose the LMT Bolt Carrier Group. They are NOT just like everyone else's... they may visually look the same to the average user but there are differences and those differences make the product more reliable and in many cases last longer.

Quite true... if I had to guess I would say that more than 50% of the companies that sell AR's and AR parts do NOT in fact make their own stuff, but buy it from a couple of main manufacturers and put their name on it or sell it as their own.
CMT and High Standard are two big names that come to mind as suppliers to many "AR Manufacturers" for a wide range of component parts. There are a couple other companies that specialize in producing BCG's and sell them to a variety of AR assemblers/resellers.
RRA buys BCG's from suppliers and as far as I know so does Spikes.
LMT designs and makes their own. I have seen some of the small differences in their designs. Their HP testing and MP inspection is to MilSpec requirments and they test EVERY unit not just batch test like many other compaies.
One of the interesting things I've seen with my own eyes was their HP testing setup and what I found very interesting was that when LMT HP tests their barrels they will use the same Bolt over and over until the bolt finally fails. These bolts don't just withstand a couple of HP tests but often withstand dozens of HP rounds while testing the barrels. Its a tribute to just how well they are made.

What about Spike's Nickel Boron bolt?
I own one.

I have had a few bolts.
Armalite, Stag, CMMG. RRA and POF.
Obviously the POF bolt hands down was the best. I would consider those a specialty product.
Second would be the Stag bolts. I would continue to buy those. They might be another CMT product, but maybe they have their own standards. The finish and quality of them are fantastic.
Far better than the Armalite and CMMG product.
edit: The price has come down alot on the LMT product. I should try one of those too!

Armalite shortens the lug opposite the extractor so it does not engage the barrel extension,it's suppose to restore symmetry under load by balancing the force using the other 6 lugs and so reducing stress on the lugs adjacent the extractor.
not sure where I'm going with this, I need sleep.

Back in 2009 there was a lot of talk about the MIM gas keys (when LMT first released them) but if you check AR15dotcom you'll see that there are no reports of LMT gas key failures relating to MIM parts.
The original request for MIM gas keys came from the military who insisted that their testing confirmed the MIM gas keys resulted in superior life expectancy... LMT instituted this change because the end result was a superior product, not an inferior product.
You'll also find this link posted on AR15dotcom...

You are absolutely correct... I do sell LMT but that's not the reason why I would choose their BCG's.
We import and sell a wide variety of brands, some of which we simply wholesale/import for other retailers (so some brands people don't even associate with us). I have access to just about any BCG I want for my personal guns, so my list of "available" brand choices is probably bigger than most other people here in Canada.
Having said that, I continually choose LMT's "standard" BCG's for my personal applications and LMT's Enhanced Carriers and Enhanced Bolts where the application warrants.
We've sold a lot of different makes and brands over the years and I've seen a lot of different issues and failures, but the percentage of "issues/failures" experienced with the LMT BCG's is low... at least that's been our experience.
With respect to Colt... I have access to Colts and I'll take an LMT rifle (and parts) over the Colt product any day... in fact I have yet to keep a single Colt rifle in my personal vault, though I contantly have that choice. I do own several LMT's personally and have never regretted those purchases.

A recent article on MidSouth Tactical Network (MTSN) builders Wes and Paul noted that they prefer LMT bolts because of the MP and HP testing. They also measure each they get in and then get then to IonBond for a Diamond-Black coating. For basic builds they offer LMT bolt carriers which they say is good valve for the money.
According to Wes and Paul they had one of their bolts go through 24,000 documented rounds with the original gas rings.
For bolt carriers MTSN listed Young Manufacturing standard full auto bolt carriers as their top choice. They did note that for competition or extreme accuracy they will go with the Young Manufacturing National Match or lightened National Match carriers. And again the carriers go to IonBond for Diamond-Black coating along with LMT firing pins and cam pins.
The nickel boron Spikes BCG does look nice. I really don't know much about them however. But I think the nickel boron coating is similar to the electroless nickel coating LMT uses on their enhanced bolts.

Nickel Boron === Fail Zero bolt
Personally, I like them because i shoot A LOT OF ROUNDS... I mean, I burn though parts & barrels like you wouldn't believe... And a FZ bolt/bcg is much easier to clean.
I find that the FZ coating on the bolt, bcg, and the upper tend to more than double the life time they survive (Things like ejectors, extractors, and firing pins of course still need replacing from time to time). They also require no lube.
As much as I like FZ coated bolts... They can cause a lot of issues & take along time to break in.
In anycase, I normally run & recommend DD & LMT bolts/bcg's. They tend to last longer than others and IMHO they run smoother.
That said, If your going to shoot less than 1k rounds though it a year... The BCG is (IMHO) not very important. Your less likely to notice a difference when compared to someone who often goes through twice that in a weekend.
This e-mail reply is from Ryan Johnson from LMT. I found it on another forum.
Just emailed LMT and received a response stating that they still use MIM carrier keys. According to the email they stand behind this process stating:
" Please know that all products we offer are made to Mil-Spec specifications per our government contracts and are tested to meet or exceed the requirements mandated by those contracts. " " However our current contracts call out for the gas keys that we use and it has been tested to over 125K without any kind of failure. We did copious amounts of testing with the new keys with the military and have found that what we use now is superior longevity and durability wise to the forged keys we used to use."
"All I can say is trust in what we are doing as the President of this company will not put his name behind anything that isn’t tried and true or doesn’t meet our quality control standards.
Please let me know if you have any other questions or concerns."
Thank you,

Why would someone from Questar use a inferior product in his personal rifles? As he stated, I'm sure he has access to far mor BCG then most. Stands to reason he would chose the most reliable one.
Yeah I went an ordered another one for my Noveske, should have just got an LMT from Questar....always good to try different brands..
Yeah, thats the only way to build up lots of experience and a real, solid, well backed preference.
Most of my bolts/bcg's I buy whatever's the cheapest. I have certain preferences, and for certain guns/applications I will accept nothing but the best, but most of the time I'll use whatever I have.
