35 Cal AR

Given that it is a straight wall cartridge why couldn't you simply take a .378 inch reamer grind a .348 pilot on the front and run it to the proper depth for head spacing on the case mouth? Then manually put the chamfer and radius at the chamber mouth. This seems like a pretty easy chamber to fake with standard tooling if you are only doing a few barrels.

This would work, and you could even rent a throat reamer for 357 to finish it up. But the standard tooling is expensive too, and most dont have it laying around. I've debated this one too, a custom reamer is $190 and a barrel blank would run about $80 if I remember correctly. Extensions are cheap, but the break even cost is about 10 barrels. Need to decide how bad I want one before I jump in...

I could be tempted into a barrel if you get serious. This sound like a very interesting cartridge that once you have the barrel all the rest of the parts are standard or modified from standard. Sort of a little (and faster) brother to my 450 Bushmaster.

I am not a machinist. That is an idea.

Don't know why it wouldn't work, but I've never reamed a barrel and I'm not exactly an experienced machinist.

Somebody starts making barrels, I'll snap one up.

I would be on board for one also.
I've walked into the LGS 3 times to buy an AR but left because I can't force myself to get a 556.
