A quick search of sold LF rifles on
Gunbroker (it's easy, really) shows them selling from approx $900 to $1500 with most in excellent condition having original box & paperwork and some unfired ANIB. If it's been used and doesn't have the box then it'll be on the low end. If you're using the NRA "Good" rating then it's more likely a $5-600 rifle.
