The M1752 Musket was a muzzle-loading firearm invented in 1752 and used by the Spanish Army from then until it was widely replaced by the much more effective Minié rifles during the mid-19th century. The M1752 was the first standardized long gun utilized by the Spanish military and was deployed in Spain's American colonies, where it saw action during the Battle of Havana. Spain also provided around 10,000 up to 12,000 muskets to the American rebels during the Revolutionary War.^[2][3]

Proving typically conventional for the period, the weapon maintained a long service life under the Spanish crown and was deployed to its various frontline forces across the various Spanish holdings. The Model 1752 was in widespread circulation up until the middle of the 1850s by which time more and more fighting forces were adopting more modern Minié ball-long guns (categorized as "rifled muskets").

The M1752 saw some later modifications in 1755 and 1757.

The Model 1752 Musket featured design qualities associated with this period of land-based warfare (in general line infantry)—these were long, heavy guns made primarily with a single-piece wooden stock housing the steel barrel and works of the gun lock. As muzzle-loading weapons, they were loaded down the muzzle end of the gun which necessitated use of a ramrod held in a channel in the stock under the barrel. The stock was affixed to the barrel at multiple points, usually two brass barrel bands and a nose cap at front and which had a ramrod pipe cast to it. The firing mechanism was of the flintlock method requiring a piece of flint to be seated in a vice and cocked rearwards prior to firing. Additional steps included the loading of black powder both into the pan and down the barrel, prior to inserting the rest of the ammunition consisting of both a musket ball and paper cartridge which also doubled as wadding. The wooden stock incorporated a slightly angled grip that extended downwards to become the shoulder support (or shoulder stock), capped with a metal butt plate. Fixtures along the top of the barrel allowed the gun to be aimed. The trigger was set within an oblong ring (trigger guard) under the action as normal. While the rest of the musket outwardly resembled other muskets of the 18th Century, the lock was unique, being of the characteristic Spanish "Miquelet" type. This action reworked some of the accepted design practices of the flintlock—mainly at the mainspring and hammer (or cock).^[4] Eventually, many were converted from flintlock to percussion cap in the mid-19th century.
