Barrel swap fail - I stripped that little hex screw :(

[wahoowad]

I don't know if anyone answered your question about the barrel set screw or not. But it should be tight and definitely should be touching the barrel. How did you know it wasn't?  Could you slide out the barrel from the breech without loosening it??  Man, that's a bad quality control issue. That one needs to be tight.

Yes, barrel slid right on out. But I did tighten it down at reassembly
