The TRG Action Wrench facilitates barrel removal for the Sako TRG-22/42 rifles. Now you can turn your TRG into a “switch-barrel” rifle with this wrench and a barrel vise. Gunsmiths can use this for barrel replacements and avoid fabricating their own wrench. This is the first and only action wrench available for the TRG rifles. It is intended to be used by those qualified to remove and install rifle barrels.
