The Vincennes RK has a well-stocked firearms section.
RK and Big R are both fed from the same warehouses, I would imagine the prices will be similar. The Big R in Marion has had guns for some time, and if the pricing holds the same for their guns as it has for their other products, they wont have their doors beat down for their killer prices, but they wont be Dons guns expensive either...
The people who work there don't know much of anything though
