LY19 Advanced Light Machine Gun
http://i205.photobucket.com/albums/bb62/2821090/LY-19LMG.jpg
Weight: 6.7 kg (unloaded)
Length: 950mm (stock extended)
780mm (stock compressed)
Barrel length: 600mm (23.62 inches)
Cartridge: 6.8 x 42mm frangible
Action: gas operated, rotating bolt.
Rate of fire: 1,015 round/min
Muzzle velocity: 868.68 m/s (2850 f/ps)
Effective range: 1,400 m
Feed system: 30 round magazine or 100 round drum.
Sights: TGTM-4 MFBS (default: reflex)
Ammunition
The projectile itself is a unique design (although not a unique concept{note Australian F1 ball}), featuring a steel penetrator and lead core. Upon impact the hard steel punches a hole through armour the target might possess, whereupon the lead core, both heavier and softer, continues past the penetrator by way of its greater kinetic energy. As it passes the harder steel of the core, the lead will warp, and/or splinter. The round, in essence, combines the penetrating power of an FMJ round with the lethality of a hollowpoint.
The 6.8 x 42mm projectile is larger and heavier (at 7.48 g) than the 5.56mm x 45mm common now, and has proved to be considerably more effective in tests, even when fired from carbine-length barrels. The round has been specifically designed to ensure maximum lethality within normal rifle ranges of up to 300 m, although in fact the trajectory and terminal effects rival those of the 7.62 x 51 mm ball out to 700 m, while allowing for more rounds to be carried and producing less recoil.
Feed system
The magazine, based upon the Beta c-mag, has two drum units, each of which hold half of the 100 cartridges inserted into the magazine. Features a clear back to allow the user to see the number of rounds remaining in the magazine. The magazine functions in conjunction with an electronic counter. Specially designed composite materials used ensure minimum resistance to feeding, and markedly reduces the incidence of jamming or double-feeding over the original Beta c-mag. Exhaustive trials of the new materials, in conjunction with the have shown the upgraded drums to function with no more stoppages than a conventional 30-round magazine.
Materials and mass
The materials used to build the LY19 are almost entirely composites — with the notable exception of the cold hammer forged steel barrel, and the bipod legs. Preliminary tests in desert and arctic conditions have shown LY19 to be a rugged weapon, though some complaints arose with the bipod legs during later stages of testing in hot/humid conditions. These problems were rectified by means of a slight alteration to the alloy used in their construction. It is reported to be capable of firing 15,000 rounds without cleaning or lubrication and up to 20,000 rounds before barrel replacement, although more often is advised. An M16A2, by comparison needs to be cleaned often, and has a barrel life of approximately 7,000–8,000 rounds.
The LY19 is not a rifle, and is consequently heavier. However, due to extensive weight saving measures, at 6.7kg (unloaded), the LY19 is lighter than most LMGs on the market. At 950 mm, it is also fractionally longer than most weapons in its class. This is further enhanced by good ergonomics and effective distribution of weight.
Rifling
The Lyran Protectorate, under licence from H&K, has re-engineered the H&K design for octagonal rifling, in order to amplify the effect of the relatively long LY19 barrel on muzzle velocity. These higher velocities are brought about by reduced friction to the bullet in the barrel, as the octagonal rifling has less surface area than the peaks and troughs of conventionally rifled barrels. Further, there is a notably lower instance of bullet deformation within the barrel, resulting in reduced drag and a corresponding increase in accuracy and range. When coupled with the already long barrel brought about by the bull-pup configuration, the muzzle velocity of the LY-19 exceeds that of most of its competitors by a considerable margin.
Electronic bullet counter
Electronic bullet counter, located above and to the left of the trigger, tracks the number of rounds fired and the date and time of each fire. The display does not show unless the firer activates it, so as not to give away his position in certain circumstances. In addition to it being far easier to check number of rounds remaining by looking at a display than trying to count rounds, the data can be accessed and uploaded to third party systems. The tracking will greatly improve the ability to keep tabs on weapon wear and tear, and make it easier to identify weapons that are in need of overhaul or new components. The battery life is a few years, thanks to an ultra-low power circuit and a comparatively large battery, held in the hand grip.
Sighting system
Lyran TGTM-4 is a multi-function battle sight (MFBS), factory zeroed in all modes. It combines a default reflex sight (with adjustable brightness, as per M68) with a night weapon sight function, night aiming device (boresighted at 100 metres), manually operated optical zoom with autofocus, adjustable reticle selection, and firing-position-safe grenade launcher sight toggle. A bullet-drop compensator is also available as an overlay to any fire mode, accessed by toggle switch that does not require the firing hand to be moved from the pistol grip. The sight is water-tight down to 50 metres, and is free of parallax error at ranges outside 30 metres.
Problems suffered by the TGTM-2 and -3 regarding the requirement for regular battery resupply were recified in the -4 by linking the gunsight to the battery included in the LY19's handgrip, which also operates the electronic bullet counter. The battery provides the gunsight with 60,000 hours of constant operation in normal combat conditions, and is rechargable from the AC outlet featured on most Lyran vehicles, or a regular 240 volt power outlet.
