I have hunted a little with all of my RBLs, but I've really settled in to hunting with my RBL-16. Mine are all straight stock, slim forearm, double trigger guns. Mine weigh --
RBL-28 with 30-inch barrels -- 5 pounds 12.3 ounces
RBL-20 with 28-inch barrels -- 6 pounds 3.8 ounces
RBL-16 with 29-inch barrels -- 6 pounds 14.8 ounces
RBL-12 with 30-inch barrels -- 7 pounds 4.9 ounces
Don't have a picture of all four, but here are the 28-, 20- and 16-gauges --
Here is the RBL-12 and the RBL 16 --
My RBL-12 is one of the lighter weight ones on the same frame as the RBL-16. Kind of like a 1-frame Parker Bros. 12-gauge. I originally got one of the big frame 32-inch 12-gauges with a beavertail and vent rib that tipped the scales at 8 pounds 14.5 ounces. Didn't like it at all, even though it was exactly what I had ordered. Lou took care of me and got me the lighter RBL-12.
