The first general-issue British Army rifle, introduced in 1855.

It replaced the Pattern 1851 Minié rifle, the first British weapon to be made using interchangeable parts, thanks to the American system of manufacture. This was closer to the modern production line than the previous Ordnance System which relied upon civilian cottage industry.

The ‘Enfield’ name comes from the Royal Small Arms Factory at Enfield where the rifle was designed and this ‘Sealed Pattern’ reference example was made. It is also where the original Pattern Room, the predecessor of the National Firearms Centre, was located.
