Dead caliber impractical build.

[Itchytriggerfinger]

Let's just say there's a guy and this guy loves .40 caliber anything and the odder the gun, the better. Now this guy wants a .40 AR with a 4.5" barrel and a pistol brace. Anyone know, speaking hypothetically of course, where a guy would start his search for such a build?

Macon armory builds a 10mm upper. I'm sure he could turn you it a 40 barrel and bolt.

Yeah, I'd go with Rudy at Macon Armory. Good thing about a 40 cal AR is that factory 180g FMJ are already sub sonic. Probably about the same price maybe a little cheaper than 147/158g 9mm

Came for a thread about a 8x50r AR-15. Leaving disappointed.

There's a bolt in the classifieds.

I believe Rock River Arms sells 40 cal uppers, mag well blocks, and magazines... or at least they used to.

Aren't we still mad at Rock River?

 

[Cameramonkey]

Who ARENT we mad at anymore?

You have to be careful in what threads you read on INGO. They can be hard on the wallet. I dropped into this one just out of boredom and now find myself thinking that I need to add a .40 AR Pistol to the family. Don't know why, but it seems like it would be a cool project. I have a .300BO pistol that I don't shoot much but a .40 would be a nice one to run for fairly little money.

When I get this one done I'm going to try and build a .50 AE. What can I say, I'm a sucker for "oddball."

I've been debating a 460 Rowland ar
