Got one, thanks!

Does it matter that they are designated .223 and not 5.56? Just curious since they are technically not the same round and 5.56 operates at higher pressures.

Here ya go...

Edit: per multiple sources the bolt face is identical for 5.56 vs. .223; no worries

Maybe I am just a little out of it, but I am confused why there is such a demand for BCGs right now... Even if AR's some how become banned, BCGs will still be able to be purchased...

A lot have partially assembled AR projects and the Bolt Carrier Group supply has been dried up for a while. Thanks for posting the link.

UPDATE:

Ni-Bo is out of stock again, ceramic still available.

 

[DRob]

He who hesitates

The Stoners are out of stock. The $300 ceramic coated BCGs are available...
......as of 3:40PM.

Yep, they're gone. The only dimensional difference between the .223 and 5.56 is a little radius at the shoulder, not enough to cause any difficulty loading either one into the other's chamber. Therefore the bolt is identical. The bolt carrier will be the same even for different calibers. The issue differentiating the two is the higher pressure of the 5.56, which is addressed with the chamber. The bolt is irrelevant to that.

Ceramic coated is still in stock, amazingly enough.

Ni-Bo back in stock...

...and gone again.

Wow, the reviews on the AR-Stoner BCG's are pretty terrible given total review count to negative review count. I read on another forum that several reviews had been "removed" as well. While I have no experience with them or their product it's probably worth noting they seem to be hit and miss based on reviews.

 

[cbhausen]

I'm sure if there was a dimensional problem it has been fixed by now. AR-Stoner is Midway USA's house brand so you can be sure they'll stand behind the product. I went ahead and ordered one; we'll see how it goes.

 

[aclark]

Dont know if its always the same manufacturer or not, but the one I just got in the mail today was made by SMI...Signature Manufacturing.

 

[cbhausen]

I just got mine and if it runs as good as it looks I'l be happy. Everything except the firing pin is Ni-Bo plated and I don't see any flaws at all. Hell, even the cotter key is plated. The coating is uniform and everything has a fine bead blast finish. The decal on the bag does say SMI just like aclark said.

EDIT: And here it is from the source. Even the number on the tag matches.

OK, silly question, but I've never had a full AR. I'm looking at doing one with a dedicated .22LR upper. Does that need a different BCG or does the dedicated upper have a way of striking the rimfire primer with a centerfire firing pin?

Note that I said, "silly question", not "dumb question". The only dumb question is, "Is it loaded?", and that only because they all are. *nod*

Blessings,
Bill

 

[cbhausen]

Never done it but I think you can go with a dedicated upper or one of these (some in-stock BTW):

.22LR Conversion - AR-15

 

[Leo]

The dedicated upper is self contained, The mechanism has it's own bolt, firing pin, recoil spring etc. No need for a normal BCG

 

[aclark]

The only flaw in this BCG that I can see its the poorly staked gas key, although its really now worse than my DD BCG. Cycled the bolt on a few rounds, the first 2 failed to feed, but the other 28 cycled fine. Granted I wasn't firing it, just pulling the charging handle.

 

[cbhausen]

Correct. And the CMMG kits replace the BCG and have a chamber insert.
