Hey guys, I want to try out a 600mm Barrel if anyone has an extra laying around willing to part with. I can trade for a 500mm in 30Cal, or I have lots of other FX parts willing to trade up or down. I also have some scopes and Gamo Coyote, BSA Buccaneer, Avenger etc. Hoping to find a heavy liner with Carbon Fiber Sleeve but let me know what you have.
