I don't think folks are as willing to fork over the bread for a 16 like they will for a 12 or even a 20.
You would be thinking wrong.. Especially if it has a vent rib barrel.
I have sold 3 of them this year..
#1- Used with non vent barrel $450
#2- NIB with Vent Rib barrel fixed choke $1600
#3- NIB with Vent rib barrel and Remchoke $1450
Side note- 870 Wingmaster 16 with vent rib and was completely NIB went for $2100 on GB around last summer. Completely lucked into that one.
Most dealers will snuff their nose on 16's and not bother with them which leads to most thinking they will not bring much. 16's have a hardcore following of people with fat wallets.
