Bill,
I agree, they're pretty nicely machined inside. Very much about like the quality of my Beretta and much nicer than the current Browning insides.

One goal that Tony pointed out about the RBL was that they were machining the reciever and barrels to fit. I'd be interested in your assessment of whether they met their goal of that fit (whether the barrel breachface appears to have been hand fit or machined).
