I'm not too picky. I am just looking for something to throw together another 9mm upper. I miss my old one. Length isn't a concern (it may go on my SBR)....don't want an upper assembly, just a barrel. Let me know what you have. I am looking for a good deal.
Editted to add: I am going to use a Colt/RRA style bolt...don't know if that matters, but it must be compatable.
