The big deal is plain and simple. American made (as mentioned before) and the simple fact that a gunmaker that makes 12K to 100K guns has decided to enter the "affordable" double gun market. What do you think the buzz would be if H&H or Purdey decided to make 3K boxlocks. I think you would see 20 pages of BBS BS about that project as well.
This is just the beginning for the RBL. I know there are plans for this gun that include other options and gauges.
Form the guns I have seen in person and on the net I will say one thing; Galazan's smiths know how to apply an oil finish. Some of the oil I have seen applied to European guns look like the finish on a lumberjack's axe handle.
