The Haphu musket (Quenminese: Súng hỏa mai Hà Phú) was a musket utilized by Quenminese heavy during the Lận Dynasty. It features a miquelet lock and a retractable, ready-to-use cartridge. Of its breechloading system, the retractable cartridge proved to be a unique mechanism, as it virtually eliminated the use of the ramrod to secure the musket ball in the barrel. Though, a ramrod was used for backup.

Although it was designed for light infantry and despite its advantages, it was redacted due to the expensive cost of manufacturing and of cumbersome issues originating from its loading mechanism. However, it was still used for troops mounted on elephants and in the naval forces.
