The old 'dirty 30' has the happy distinction of being #2 in cartridge popularity behind the .30-06. Ammunition is virtually everywhere. These carbines were designed to be hand carried or secured in a scabbard. Sings are more hassle than help, especially in heavy brush. You can always tie off a paracord sling if it's really neccessary. Scopes also defeat the fast handling and compactness of this rifle. You could put a forward relief scout type of low power. Peepsights will give an additional 25 meters of effective range with teh ballistics. The practise is to remove the aperture and use the threaded hole as a 'ghost peep' in which you look through and line up the front sight and target.
