I think it's ok to post a link to an add in the EE here (any one else ever notice Indiana has the best mod around?).
I've got an add in "AR15 Complete Firearms & Lower Receivers" for a NIB Bushmaster XM15 E2S:
It's brand-new & unfired. I can deliver it wherever you want in Indiana for $700.
Still got a ton of other stuff, but I don't want to float that thread, GB kinda wants everything traded/sold to start going through the EE.
