The Wingmaster is Remington's top of the line, deluxe sporting shotgun.
It has a polished blue job, American walnut wood with the famed Remington "Bowling pin" finish in gloss or satin finish, a chrome plated bolt, a more polished bore, and better checkering.
The Express is Remington's budget model.
It has a bead blasted flat black blue finish, hardwood stocks with a varnish type finish, a lesser polished bore, and lesser quality pressed-in checkering.
Also, the Express has a rougher finish under the bluing with more machine marks and some burrs left, inside and out.
The Wingmaster is the Cadillac, the Express is the cheap Chevy.
