The origins of the modern British military rifle are within its predecessor the Brown Bess musket. While a musket was largely inaccurate over 80 yards, due to a lack of rifling and a generous tolerance to allow for muzzle-loading, it was cheaper to produce and could be loaded quickly. The use in volley or in mass firing by troops meant that rate of fire took precedence over accuracy. A similar tactical preference would be a factor in considerations regarding rifle design in the late 19th century and early 20th century, when rate of fire would be a key design consideration for British bolt-action rifles.
Beginning in the late 1830s, the superior characteristics of the new rifles caused the British military to phase out the venerable .75 calibre Brown Bess musket in favour of muzzle-loading rifles in smaller calibres. Early rifles were non-standard and frequently used adaptations from components of the Brown Bess, including locks and stocks adapted to new rifled barrels. It was not until the late 19th century that the rifle fully supplanted the musket as the primary weapon of the infantryman.
Civilian rifles had on rare occasions been used by marksmen during the English Civil War (1642–51). In the 1750s, a few German rifles were used by British light infantry regiments in the French and Indian War.
In January 1776, 1,000 rifles were ordered to be built for the British Army. A pattern by gunsmith William Grice, based on German rifles in use by the British Army, was approved for official issue as the Pattern 1776 Infantry Rifle. The barrel is 30.5 inches with hook breech in .62 calibre. Eight hundred were delivered through four Birmingham producers: William Grice, Mathias Barker, Galton & Sons and Bejamin Willets. Two hundred more were obtained from Hannover.
This weapon was issued to the light company of each regiment in the British Army during the American Revolution; these were probably present at most battles in the conflict.
Also in 1776, Major Patrick Ferguson patented his breech-loading Ferguson rifle, based on old French and Dutch designs of the 1720s and 1730s. One hundred of these, of the two hundred or so made, were issued to a special rifle corps in 1777, but the cost, production difficulties and fragility of the guns, coupled with the death of Ferguson at the Battle of Kings Mountain meant the experiment was short-lived.
