Are there any builders out there in AR land that has a .357 Sig upper or barrel? I have many thousands of rounds that I never be able to shoot through my handguns so I want a .357 upper. I was looking at the RRA .40 uppers and that got me thinking about one in .357.
All the more reason to get one! It was very liberating to me to decide that I wasn’t going to try to justify by some rationale getting a whatever. Now, I just decide I want a whatever and I get one. A 416 caliber rifle is the next whatever. Utterly pointless. That’s the beauty of it.
The Bazooka Brothers thing is pretty interesting. I have toyed with the idea of a 40 caliber rifle because I have so much brass. These uppers are gas operated in pistol calibers.
