The FÉMC UHF (abbreviation of Univerzális Hadsereg Fegyver, "Universal Army Rifle") is a Granzerian selective-fire rifle developed in 1978. It was designed to replace the FÉMC AK72, AK59 and AK67 in standard service. The retrofitting of Granzerian forces began with the rifles conception in 1978 and was completed in 1987. Up to 2017 the rifle has received various upgrades. In RDF nomenclature the UHF is known as the SZ K78
- SZ K78K1: The standard production model with standard Kajetán 1.5× telescopic sight.
- SZ K78K2: The K78K2 is similar to the K781 but features a redesigned charging handle and a detachable telescopic sight which can be replaced with a modular rail.
- SZ K78K3/K112: The K112 was officially adopted by the Granzerian Ground Forces and designated as the K78K3. It was first displayed to the public in the middle of 2012 and the initial production was scheduled for 2013, its final design and testing ended later on that year. While internally and externally the K118 is still similar to the original UHF, it has received many distinctive upgrades and changes. Upgrades include the following:
1. Length of pull has been shortened by 15 mm. (The distance between the stock backplate and the grip; too long and it becomes difficult to handle on close quarters)
2. Longer top rail and a modular lower forend with side and bottom rails.
3. Floating barrel which increases accuracy.
4. Fluted Barrel which dissipates heat from automatic fire.
5. Folding charging handle.
6. Improved butt design which has increased strength and a recessed ejection port cover to improve reliability.
7. Bolt-together butt for easier disassembly.
8. Provision for electronic architecture to allow centralised control and power management of ancillary devices.
9. Primarily uses the side-loading grenade launcher (FÉMC 119GM) which can fire all currently available 40 mm low velocity grenades.
10. Improved grenade launcher mount which improves the balance of the weapon.
11. Improved grenade launcher safety.
In June 2012, FÉMC debuted the K112 at the TBA military exhibition in TBA. Key additions include a bottom rail and a detachable side rail, weight savings over the K78K2 with a base weight of 3.25 kg (7 lb) and the large trigger guard has been reshaped to serve as a vertical foregrip.
