.260 Rem AR10 ?

[stormblue]

I'm thinking about building an AR10 chambered in .260 Rem.

Who makes AR10 barrels?
I've checked a few websites.
Pac-Nor's web sight links to Noveske. I called Noveske and they don't chamber in .260 Rem.
Krieger's website lists an AR10 barrel.
Bartlein website doesn't call out AR10 specifically but GAP uses Bartlein barrels so I'd assume
Bartlein makes AR10 barrels. I'm going to call Bartlein tomorrow.

Any other barrel manufactures I should check out?

Will I be able to run a "normal" gas block or will I need something adjustable like JP's?

Is there a "standard" twist rate for the .260 Rem?

DPMS LR-260

Contact GAP. You could also buy a .260 DPMS LR barrel, and use your ArmaLite AR-10 bolt -- or so "they" say.

You would be able to use a standard gas block if the gas port is done by someone knows who what they are doing.

You can use the some bolt. 260, 308...same, same.

The Armalite AR-10 and DPMS LR-308 bolts are not the same. While one might fit in another barrel that does not mean interchangeable.

Headspace is different, and there are other reasons it's a bad idea on top of that.


You should not need an adjustable gas block and 1/8 twist would be the most standard for LR .260 barrels.

Todd:

Oddly enough people claim they are using the DPMS barrels and ArmaLite bolts without issue.

I always thought it was a bad idea too, but "they" say it works. I guess we know how that goes.

Thanks,

Todd,

I'm not saying an AR-10 and a DPMS bolt is the same. 308 and 260. Sheesh. And...I'll take DPMS over most peoples work any day. They support the shooting sports.

Rich:

Take a chill pill, Todd was talking to me.

He understood what I was saying, even though you thought I was talking about bolt face size being interchangeable, I wasn't. I was talking about some people who have interchanged DPMS barrels with ArmaLite guns, using their ArmaLite bolt. Which they claim headspaces and shoots just fine.

The difference is "probably" not enough to lead to a catastrophic failure but it is not a good idea.

I understood both of you, sorry it wasn't clear.

Called Bartlein today. They only make blanks.
Called GAP they'll build me an upper.

I'd prefer to build my upper but at this point GAP appears to be my only option.
