The Floro MK-9 is a submachine gun designed by Floro International Corporation based in Tanay, Rizal Province in the Philippines. It has been marketed to Philippine security forces as a low-cost alternative to various other submachine guns and is currently seeing limited use in said country by the Philippine Marines and the Philippine Navy.
The MK-9 was most likely developed in the 1980s, but other details regarding the history of the weapon are scarce. Similarly, it is also speculated to have been produced around the same time period; the 1980s.
It is quite certain that the MK-9 uses a very rare American submachine gun as a base design, the Federal Engineering XC, as hinted by very similar appearances, but with various improvements to the original XC design, such as the addition of Picatinny rails and different sights. The MK-9 itself is a select-fire blowback weapon firing from a closed bolt. The weapon lacks a bolt-locking mechanism, with the lower receiver and magazine well being made out of sheet metal. The fire control group is from the M16. The magazine well is long and has a plastic handguard which also acts as a foregrip, and is made to accept Uzi magazines. The charging handle is located on the left side of the receiver and has a dust cover integrated, along with the rear sights having knobs to adjust windage; the front sight is fixed.
The MK19 was an improved variant of the XC 900.
Main variant. Both the MK9 and the MP9 are available in semi/full automatic versions. A heavy barrel is also avaliable for sustained fire.
The MP9 is a shortened version with a side folding stock and no barrel jacket.
