Was it bedded or threaded by anyone special?
Probably around $1000 in any case, perhaps slightly less. Resale on these rifles has fallen in the past three years. I would think the relative lack of aftermarket support and proliferation of decent, inexpensive mass produced rifles has something to do with it. The 1/12 twist, even though it is fine in most cases, also seems to be a sticking point. They are also not candidates for garage rebarrel jobs or barrel nut systems.
I sold one last year with just over 1000rds through it. It had been worked over by Short Action Customs with a new bolt knob, cerakoted barrel/bolt/action, threaded muzzle, inletted for AICS magazines, in an XLR evolution chassis. It sat for 6 months listed on multiple forums. I think I was finally able to get $1200 for it.
