I'd give an American made, mid priced gun a shot. I like your idea, as long as you can keep it cheap.
If you can provide maybe even higher quality control and better quality of assembly (don't end up making it difficult for the consumer to work on their own gun), I'd be willing to pay a little extra.
I just don't know how you plan to manage a lower price than the brands overseas, unless it requires a lot of labor that you don't make much prophet from.
Even if you just made parts that are hard to get a hold of, that could interest me (like some of the G&G parts...).
