I received the order confirmation today from Galazans for a 12ga on a16ga frame, standard wood, straight grip, splinter, coin finish, reversed double triggers and choke tubes. It will have a solid game rib. I asked them to select wood to make it as light as possible and to tell me the weight before finishing so that I could opt for 26 inch barrels if it isn't light enough.
I would HIGHLY recommend you spring for a gloss finish on your wood, specifically with a dark red/brown stain added. You won't miss the extra money in the long haul, and you cannot imagine how much it improves the look of an RBL with standard wood.
I would also recommend the case-colored receiver, but my guess is they have some coin-finished frames in stock and made you a better deal on those. Hope it is all you want it to be regardless.
