Ar made that shoots .45 acp?

The JR Carbine comes in .45ACP. Not an AR-15, but it works.

Don't hold your breath for the Taurus ones. Last update was that the rifles shown at SHOT were prototypes and that Taurus isn't sure they'll even produce the rifle. Sorry to be the "bad news" guy. I was interested in one as well.

Same here. Until the Thureons get here, the JR Carbines are the way to go.
 
As the 45ACP head diameter is the same as a 308 case, could a 308 bolt be used?

And similarly, as the 9x19 head is the same dia as a 223, do the various 9mm conversions use a standard 223 bolt?

It is possible I suppose to turn a .308 AR lower/upper combination into a .45. The larger mag well may mate with, say, a grease gun mag or a Para.

For 9x19 I am assured (online at least) that a 5.45x39 AR bolt is the ticket. Otherwise, you need a thin ring fitting.
 
I did some sniffing around after posting my question above, and it seems that the most common 9x19 conversion uses a simple blowback arrangement, no gas system and the boltface is part of the carrier.

Deckard, any links to a turnbolt system?

The 9mm system works just like that but it all depends on the buffer. The regular 9mm buffer can break the bolt catch. There is too much travel.
spikestactical.com/new/z/st9bs-p-174.html. There is also a firm that makes super heavy buffers - I think the company may be called Heavy Buffers. ???? They make them up to 14 oz.

I made my own super heavy buffer. The body was machined out of stainless steel to max dimensions. Then I used a broken 1/2" carbide endmill for the sliding weight. It ended up being about 10 oz.

Not sure I get this. A DI gas operated 9mm upper can break the bolt catch because the bolt carrier travels too far?
 
That is what I hear. I doubt the DI versions, not that there are many, would have this problem.

Search AR 9mm broken catch, ie:

9mm ARs use a very heavy bolt, compared to a .223, and the extra inertia with the heavy bolt moving forward, can lead to broken catches.
