Design changes were few; the stripper clip feed, internal box magazine, bolt face, chamber and rifling dimensions were altered to suit the .30-06 Springfield cartridge and the US pattern 5-round stripper clips, the stock was slightly redesigned, lightening it somewhat, and the volley fire sights on the left side of the weapon were deleted. The markings were changed to reflect the model and caliber change. A 16.5-inch blade bayonet, the M1917 bayonet was produced for use on the rifle; it was later used on several other small arms including the M97 and M12 trench shotguns.
