These guns were made for Sears by High Standard and are not very user friendly in disassembly. Make sure the gun is unloaded and remove the inner magazine tube. Remove the large slotted crossbolt at the rear of the receiver that goes through both wooden forearm extensions. You should be able to remove the trigger group downward. Do not lose the disconnector from the side of the trigger housing. Do not attempt to disassemble the trigger housing. If you attempt to remove the bolt, have a bandaid ready. http://www.histandard.info/manuals/sears/rfrifles/index.html
