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.

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").

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.

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.
