When prices on used ("I don't know why he dosen't want it anymore?") Rifles, approach new pricing I like to clean the factory oil from them my self.
I see them listed for 675.00 on some sponsor dealers so do the math and decide on new in the wrapper batches, with better finish and you get to send the first round down range or, trade that of for the extra Mags on the previously owned/lady driven one.
If it's a rifle you know and have fired from a friend or someone at your local club,then that would help me lean towards the used one.
