The Fixed Barrel Spacer is a straightforward accessory for shooters who need a dedicated solution for running a Rugged Obsidian suppressor on fixed-barrel .22LR hosts. It removes the need for the factory spring and pairs with the piston to provide consistent function on compatible carbines and sub-guns, while explicitly excluding certain mounts and piston combinations.
