I have a S410 SL Xtra FAC walnut stock that i purchased new years ago at Pomona Airguns. It’s mostly been a safe queen with less than a tin of pellets thru it. Condition is like new and still holds air. I haven’t shot Airguns in many years. I’m looking to sell it locally or at a Airgun show coming up in October but I have no idea what would be a good asking price. For you guys familiar with this air rifle, can you give me some guidance? Thanks for any info.
