Looking to get a good quality mil-spec spare bolt assembly for an AR15, need suggestions on which reputable brands/companies to get it from? preferably a chromium plated one, but a black phosphate one will do if need be.

Thanks

LMT, BCM, Daniel Defense, Young Manufacturing

Those would be my top choices. If you REALLY want a chromed one, Young Manufacturing.

Huh, I just checked Young and they don't have bolts listed; only complete BCG's. You may want to call them though as I bet they would still sell a bolt by itself.

Just checked

Out of stock:
LMT (6 wks)
BCM (no answered)
Daniel Defense (indefinite, they are keeping them for their full weapon build for now)
DPMS (12 wks)

In stock:
Young Manufacturing (kinda pricey, chrome $95, black phosphate $75)
Fulton Armory (black phosphate $55 - $60)

Is the Fulton any good/reliable? What about AR-Stoner? It is only gonna be kept as a backup, but still don't want lesser quality stuff.

Yikes. That sucks.


DPMS (12 wks)


Personally, I would stay away from DPMS. They have the capability to make a good part from time to time, but their QA is absolutely atrocious.

Fulton is good to go! Hrm, yeah the Young seems about $10-$15 overpriced. They make quality stuff though.

Bolt assembly=BCG?(not just bolt)
http://hamlundtactical.com/catalog/index.php?main_page=product_info&cPath=92_93_224&products_id=2937 $109

I don't know about them, but this looks like a good deal for a complete BCG.

The OP is looking for a complete Bolt, not a Bolt & Carrier group (BCG).

Also, I'd be worried about spending that little on such a critical part when even inexpensive milspec BCG's from places like LMT go for about $150.

$109 for a no-name. No thanks :)

Not really. Headspace doesn't typically stretch enough in AR's to really be a concern. You'll probably wear the bore out and be shooting keyholes long before headspace becomes an issue.

I wouldn't swap out bolts on a match gun, where bolts are typically matched from the factory to a barrel, but on a 5.56 blaster you won't have an issue.

Did these go up in price? I thought i payed around $100 for my BCM BCG a couple years ago.

Quality complete BCG's should range between around $120-$150. Higher-end BCG's, or BCG's with fancy coatings will typically start at $150 and go up.

Still looking for the 5.56 spare bolt, need second opinion.

Young / chrome $95 ETA 6+ wks / not MPI-HPT tested
BCM / black $70 ETA summer time / MPI-HPT tested, Shot Peened
Fulton / USGI black $60, in stock / MPI-HPT tested

I understand the chance of Young's non MPI/HPT bolt failing the test is slim, but would you guys go with the Young, or for the pence of mind, the BCM or Fulton? Is BCM higher quality than Fulton (Fulton buys it from a military contractor)?

Also, what is confusing the heck out of me, is that most everyone & manufacturers are stating that there is only one type of bolt for both AR15 and M16. But, Young, Larue and even DPMS, state that they are different (different cut or something in that respect and I made it clear that I was not referring to the carrier) and suggested using an M16 bolt if I already have an M16 carrier. Can someone chime in on this with some solid clarification/confirmation/explanation, because a dealer has a couple of the Young AR15, "not M16", bolt left in stock. If pics are available, that would help tremendously.

Thanks in advance

I said this in another thread where someone was asking about Stag vs. BCM.

Between those three, I guarantee that the QUALITY will be the exact same.

The MPI/HP testing is a nice assurance, but that's all it is. An assurance.

Frankly, if the Fulton is in stock, get it. It's the least expensive and IN STOCK :)

This is the first I've heard this too. I've always understood that there is no difference between an "AR15" bolt and an "M16/M4" bolt (NOT carrier).

I also know of plenty of people that put "AR15" uppers on registered lowers that function fine in full-auto mode since they have a full-auto carrier.

I can't think of any changes you could make to an M16 bolt that would make it function differently in an M16 than an AR15. Weird.

Got deep pockets? There is the LMT Enhanced bolt in stock here (http://dsgarms.com/ProductInfo/LMTL7Q3B.aspx)

Granted the features offered in this bolt are not necessary over what a quality hpt/mpi milspec bolt like BCM would offer, but if you want the cutting edge of whats out there and are willing to pay a premium for it, there is the option.

That would be a very, very, very expensive spare part to buy that the OP is likely never going to actually use.

Anyway, regarding the bolt confusion, I'm pretty sure the three people that I'd spoke with must've gotten mixed up with the carrier.

Thanks to all, I finally ordered the YM chrome. Yeah I know, a bit pricey just to mainly have chrome over the $60-70 black phosphate, but what the hell, you only live once, can't take it with you :)

The other blk phosphate bolts are just about as good, especially for the price, but I was mainly looking for a chrome though.

I did call them today going by your recommendation, they have it in stock and they said that the bolt is "not exactly the same, but it's made by the same company with the same specs", I almost went for it, but in the end, was ultimately looking for a chrome, so I end up with the YM chrome.

Other options include the FailZero bolt.

Or a Nickel-Boron coated boat (better than chrome in my opinion):

R-Guns have the Ni-B bolt for $65.

Just received my brand new Y/M chrome bolt complete, sure looks purty. Before ordering, since they were out of stock, they stated that they are in production as we speak, so I was under the impression that they manufacture it themselves in house. But, just found out that they do not, they have them shipped it! Interesting...

Chroming is a toxic process and highly regulated by the EPA. Most machine shops send parts out for chroming, even when they do the machining inhouse. Are you saying that YM is buying chromed bolts fully manufactured by a job house, and slaps their name on them? That brings up the question if whether they manufacture/machine their standard bolts either. In that case, why would you pay a premium price for a bolt with their name stamped on it, when they didn't even make the part?

That's the final impression that I got from them. Since I got it from a dealer and came in a ziplock bag, I called Y/M to see if I can verify that it is theirs, since there is no name stamped on their bolts. They said "there is no way to tell and that they have them shipped in", in those exact words. So, I'm assuming that they have a contractor manufacture the bolts for them to their specs, just like BCM, AR Performance, Fulton, etc. With Fulton, all the little spare parts that they sell, they have a contractor make them to their specs, that's what they said, which I would guess it's the same with companies like DPMS, etc. I don't mind if the bolt is not made in house at Y/M, as long as it is a good bolt, that's all it matters to me. Look at the AR Performance 5.56 bolt page (http://www.ar15performance.com/inc/sdetail/3255/5274), it state that it's from the same manufacturer as BCM.

Even a lot of car manufacturers will out source to have some parts made by a contracting company, I would say that's somewhat the norm, so that should not be a deal breaker. What's important is that if something does goes wrong, will the company stand behind their products.

Do you need to worry about or check headspace when you buy a spare like this?

Yes, you should. Every machined part has plus or minus tolerances. The tolerances can add up to where the headspace is out of spec.

Yes, you should. Every machined part has plus or minus tolerances. The tolerances can add up to where the headspace is out of spec.

Some say that it should be done as a precaution, even though there is a VERY slim chance that the headspace is off, as long as the new bolt is mil-spec and the barrel is new or pretty new. Especially with a new or almost like new rifle, since it takes a tremendous amount of rounds to change the headspace, some big name gun manufacturer state that it is really not necessary. Daniel at YM stated the same thing and that one would have a better chance at winning the lottery, compared to the headspace being off enough to blow up in your face.

Here's a excerpt from a post found on ar15.com

I had a Dealer that was a Smith, and he also had the Colt contract for warranty work. He said in 30 years of business, and working on AR's, he never checked HS on new, nearly new sticks.

BCM BCG's usually move pretty fast. you can subscribe to a email notification when they return to stock. usually in a day or so and you receive the email early in the morning. So you have to be fast to get one.

how much? (if you dont mind)... I really don't need chromed - as it's an added cost unnecessary for back up bolt - but I guess if it's a good price it's worth considering... thanks for the info
