Seems to me,( from the images) that they chose a simple "new look" finish that is easier to apply. Prob a quick tumble,vapor blast, dip process to get an even, clean new look.
should be no problem to scuff the finish down with 0000 steel wool if it's not clear coated, and the dull finish suggests it's not.
If dipped, the inner surfaces should be colored as well.
Maybe an adventurous member can disassemble it and test the scuffing on an unseen inner surface?
should also be strip able and refinishable too.
Anyone know if the butt plate polished and painted or plated?
im wondering about the finishes on the kit. Is it raw or finished and just needs assembly?
I am hoping raw!
