Id call USO and see what you want on it and what kind of deals they can give you, from what ive heard the folks at USO are grade A people and will go out of their way to make customers happy.

I would just call and place an order for a new one.. I watched the FS section for a long time and never saw any 3.8-22's come up. Only downside to ordering is you gota wait 5 to 6 months for a new one.
