Thanks for the welcome! Yeah. I'm in cartel hell above and below ground and an aiding and abetting local gov. that for a final month I'm still employed by.
So I don't have a bunch of guns since I split my allowance with musical gear too :) the rest is family. If I were to choose between the 10 and the 15, with the help of some of the valuable information here, I'd probably go for the 16" 308 and start reloading. When I clear a few more projects and stabilize funds, I'll get the 15 with the x39 upper. That just keeps gnawing at me!
Interesting post regarding the Colt. I was unaware. Maybe they didn't get past the Gen 1 failures which have all been addressed at this time. The extended pin, hammer spring. etc.
