My great grandmother recently gave me her remington 870 wingmaster. This is my first shotgun and need a lot of help. First how do I figure out the gauge? Where can I learn basic operation of the weapon? And how easy is to upgrade it a bit, want the tactical look.

Classic gun. No need to go tactical. Gauge could possibly be on the barrel!

Gauge should be on the underside of the receiver and likely marked on the barrel as well as the chamber length. Probably a 3" chamber.

Seriously?? you want to make a Wingmaster into a tac gun?? Think im gonna be sick! Wingmasters are classics! Buy a newer 870 and mod it, leave the winger alone!
