Rem, my Superlight weighs 6# 12 oz, with Browning’s flush choke tubes. In some of the previous runs of these guns, they made some with alloy receivers, designated “Feather” along with the model. These are significantly lighter, but I find the dynamics atrocious.
I find the dynamics of this gun suits me just right, slight weight forward bias.
If you need a 16 gauge that comes in at 6 1/2#, consider a field grade Winchester Model 12 with plain barrel. Mine, with 28” modified choke barrel weighs 6 1/2# on the nose. It’s my favorite chukar gun.
