I have a G&P M4 w/ Skull Frog Engraving http://www.evike.com/product_info.php?products_id=32129 And I'm wanting to sell it. I was wondering how much it is worth and what the is best price to list it at (Reasonable, not too high so that no one will buy it and not too low so I'm not loosing money). I bought it in February for about 280 on Evike.com and I have tuned it recently (reshim, AOE, regrease, etc.). It has a few scratches from wars and so I was just wondering what you guys would say is the best price to sell it for! Thanks!
