I just ordered a stainless DMB bottom support metal and stainless magazine from Savage. My 6.5 Creedmoor model 16 came all stainless except for the plastic DBM frame and magazine. Since I have been shooting my 10TR with metal DBM, I really love the better quality of the metal magazines.

So I called Savage: Parts in stainless are from the Weather Warrior

Frame assy black metal: #107325 $78
Frame assy Stainless metal: #106705 $86

Stainless DBM magazine: #55109 $60

I screwed up and didn't get the Stainless trigger.
