I thought it was pretty common knowledge that you never get what it's worth(gun dealers,car,etc...) Think that's why they call them dealers. Sell it, good luck
You have to remember thay do not need your gun they all ready have there own. So by buying the gun from you is doing you a favor, not them. They are going to pay a little as they can for a gun and sell it for as much as they can. They are in the business to make a profit. If you do not like the offer they give you then sell it as a private party sale. It does not matter how many rounds are through the gun. It is used, period.
