In 1915 the UK could see that war was on the horizon. As they tried to build up their army they found themselves facing an acute shortage of firearms. The army had priority so other branches of service were particularly hard hit. On April 1, 1915 the UK placed an order with Remington for 4000 rifles for the Royal Navy Air Service. The Royal Navy Air Service was arming small craft for defense of the coast.

Canadian inspectors came to the Remington plant to select the rifles and marked those selected with the DCP proofmark. The DCP proofmark is made up of crossed flags a crown and the letters DCP standing for Dominion of Canada Proof. This rifle has this proofmark.
