G'Day Fella's,

Rell, some great advice above but if you plan to hunt in some wet and remote locations, I like to have a floor plate. It makes it easier to drain and clean out the water, and other crap.
The alternative "Tac" that I use on blind magazine rifles (and great for all hunting rifles), is to Cerakote (Air Cure version), all the metal surfaces. This gives all but in particular the inaccessible/under the stock metal surfaces of your rifle, some robust protection from corrosion, whilst in the field.

Hope that helps

Doh!
