I bought an RBL-16 and my hunting partner, at my urging, bought one also. When the guns arrived they weighed 7lbs, 4oz which was much heavier than the advertised weight of: 6lbs, 4oz -6lbs, 8oz. Since we are basically upland bird hunters, these guns were just too heavy. They also felt bulky and I found neither of these conditions pleasant.
I felt a bit guilty and traded my partner a Zoli Expedition 20 gauge and took his gun. He got a good deal and I got off the hook for advising him to buy it in the first place.
I sold his gun and traded my gun for a second (used) RBL-28 and gave a little cash.
Basically, I don't consider the RBL-16, as delivered to us, a game gun.
I own an Ithaca Classic Doubles Grade 4ES in 16ga. that was made specifically for me and the only one in existence with two sets of 16ga. barrels. It weighs 6lbs, 2oz with either set of 28" bbls. Now, that's a game gun.
