If I were doing this I would probably NOT go after a large market, like hunting rifles or the general tactical rifle as they are already very well represented. Unless you can innovate with something new, and in fact that would be your best option, you will end up in a price war. Being the new kid on the block you then have to be the cheapest - the low Canadian dollar is your friend so this can help, but I would try and find a niche market that is underserved. You would need to sell to the US market to make this more than just a hobby. You need a great online presence, so just use Shopify right off the bat, and you will be ahead of a lot of Cdn gun related websites (there are exceptions like Wolverine, Grouse River etc). My personal wish would be for a fibreglass composite type stock for a drop in Swiss K31 barrelled action in a competition or tactical style stock (competitors are McGuiness stocks, beautiful, drop in ready, wood, but $700 Cdn and Boyds; $100 Cdn, wood, need to work it yourself, looks ok, not sure about the fit). i might also consider making left hand composite stocks for the Savage Model 12's (benchrest, F TR, Palma) but you need to research the viability of that. There could be an existing base of left hand owners that might jump on it. Maybe team up with a local smith to come up with something new?
