Jody,

This is quite an interesting question you pose. I would say it has to be as close to the
actual AR lower as possible, while maintaining all the functionality fit and finish of the
15-22. I would say that threaded for a receiver extension tube is a must, as is the
ability to use any standard AR trigger guard.

Price is going to be the sore point. You will be machining this in the U.S.A. out of
Billet T6065, I'm thinking it's going to be hard to match the price point of a standard
AR Forged Lower and I'm not sure if anyone is going to spend "billet money" for a
15-22 lower (which also has to go through an FFL).

I would think we would be better off if you could machine a T6065 Billet Upper rather
than a lower? I dunno! Either way I want to see it happen!
