Clayton, welcome to the ALR. You've chosen quite a challenge for your first rifle, but you have come to the right place. I would recommend you do a search on both the Baker rifle, and also the Rifle shoppe, for some background info, and tips on both the rifle, and dealing with the shop. I don't do this to discourage you but to give you a heads up the their supply line is sometimes quite slow, as a lot of component sets are cast when ordered, and may not be in stock. The best advice is to be persistent with phone contact, and call to check availability of the Baker parts set. From checking your site, it appears you have the skills. Good luck.
Bill
