If it is a heavy barrel it is not a model 16. The only Model 16 they show with a DBM and accustock does not have a varmint barrel. Maybe they did do a special run just for Cabelas I dont know.

The guy shoulda been able to give you a model number though.

It is could be a 12fvss, but they dont show it coming with an accustock or a dbm.

Here's what models come with the accustock, and the 16fcss fits your description best, only it is a sporter barrel.
