Accessories include a special sub-calibre barrel (painted silver) for firing blanks and low-powered gallery ammunition. When firing blanks, a cone shaped blank firing adapter must be attached to the threaded muzzle of the sub-calibre barrel (and secured by a clip) to ensure the mechanism has adequate pressure for its blowback operation. Other accessories include night sights (wartime use only) that attach to the fixed day sights (f: protected post, r: L-type), a brass catcher for collecting spent cartridges (peacetime use only, for reloading and recycling), a quick-detachable (by attached cord) ejection port cover (painted bright red) for guard duty which secures the bolt from accidental firing, and a magazine loader that loads a magazine from a cartridge tray in seconds. The m/45 was also issued with a standard cleaning kit containing a threaded cleaning rod, threaded jag and a container for the jag, lubricant and cleaning patches. The standard sling issued was made of leather, attached to the rear left receiver and left barrel-sleeve sling bars.
