Rifles were proofed at arsenals like the Benicia Arsenal in California. Not all of the Remington MN rifles purchased by the US were marked with US Ordnance stamps but many of them were, look for small eagle head stamps with numbers on the stock and receiver. At least 50,000 Remington M1891 rifles were shipped to the Czech Legion via San Francisco and Vladivostok. These rifles were used in basic training camps, SATC and ROTC units, and were supplied to some National Guard units who were forced to turn in their 1903 rifles for the American Expeditionary Force going to Europe. The US government cancelled all contracts for war supplies to the Communists, and bought 300,000 or more Mosins directly from Remington and New England Westinghouse. You should also know that many Remingtons were never sent overseas but were purchased by the US government for use by the US Army and National Guard, after the Bolsheviks seized power in Russia in 1917.

Yes, it is possible that a worker took a rifle home.
