Without doubt the best rifle of the First World War, possibly barring the SMLE. This all depends on your definitions, though.
Rugged, rough, reliable, massively strong, excellent sights, this is the rifle the Americans are still trying to forget. A British design based on a German original, this rifle armed two-thirds of all American troops to see combat in the Great War.
After the war, it was the origin of the Remington Model 30, which started Remington to building modern bolt rifles. This makes it the origin of all Remington bolt rifle development since the Model 30. It also was the inspiration (with little change) for the Winchester Model 54, which is a slightly-remodelled M-1917. The pre-'64 Model 70 is a slightly- redesigned 54! This makes the 1917 the direct ancestor of ALL American-produced bolt action rifles since World War One.
During the Second World War, they were used extensively as training and guard rifles in the USA, Canada, Great Britain. As the original P-14 and as the M-1917 both, they continued in field service as sniping rifles when more modern equipment was not available ..... or perhaps not wanted. They can be superbly accurate and it is NOT a lot of work to get 1 MOA out of most of them..... if you can shoot and are careful.
They have exactly ONE failure point: the ejector spring. When one of these goes, the best solution is to install a new spring made from half of a ballpoint-pen spring. This (coil-spring) will last just about forever.
