The U.S. Rifle has been often called the Enfield, or the P-17. While both of these conjure
up a vision of the same rifle, technically neither is correct in military terms. Officially, the
.30-’06 version of the British design is known as:
The United States Rifle, caliber .30, M1917 and is described as a breech loading rifle of
the bolt type. It is sometimes called the Enfield rifle (extracted from the War Department
Basic Field Manual 23-6), since it was developed at the Royal Small Arms Factory located
at Enfield Lock, in Middlesex and located approximately 11 miles north of London Bridge
on the outskirts of London.
