FX 700mm .22 Liners Anywhere?

Andy, You will need more than just the liner if you are moving from the compact to the sniper 700mm. You will need to buy the 700mm sleeve as well for your new Harmonic Balancer to mount. The FX 700mm kit might be the way to go for plug and go, or, you can get each of the separate parts from FX to make up a 700mm sleeve set. Used ones come up often on AGN, and for you, caliber might not be relevant, so your options are open. Plan "B" could be to cut the back of the carbon fiber to the proper length for 500mm and reinstall (after threading the carbon fiber, or, resize the guide threads) the shroud guide. Rick at RMPA (Rocky Mountain Precision Airguns) in Longmont can help if you are in need.
