Swan Barrel Liner Carbon Fiber Sleeve and Barrel Spacers

One pair of Swan Carbon Fiber Sleeve and Barrel Spacers CF Sleeve Spacers are designed to replace FX Barrel Liner OEM spacers with o-rings. Centers the Carbon Fiber sleeve and barrel liner within the shroud. They are sold only in pairs. Benefits include: - Barrel centering, a larger footprint to stabilize more barrel and liner surface, and reduced harmonics resulting from the force of the shot. - Tensions the barrel without the added stress and maintains a more consistent POI. Proper Fitment: - Place one directly over the middle of the Carbon Fiber Sleeve, which houses the barrel liner, and one 1.5 inches from the muzzle end of the Carbon Fiber Sleeve.
