The U100 MK5 in real life.

The U-100 MK5  is a Singapore-made 5.56mm light machine gun, developed by the Chartered Industries of Singapore (CIS, now ST Kinetics). The MK 5 variant is an updated variant of the MK 4, which was developed for the USMC's Infantry Automatic Rifle competition; the Ultimax lost to the HK M27.

Battlefield 4


The U-100 MK5 is a light machine gun introduced in Battlefield 4. It can be found as a collectible in South China Sea equipped with a Prisma sight and bipod.


The U-100 MK5 appears in the Battlefield 4 multiplayer as the first LMG for the Support class. Its initial attachments are an HD-33 sight, magnifier, muzzle brake, and bipod

It has a low rate of fire, moderate damage, and very good stability.

The stubby or potato grips further increase accuracy in full-auto, while the ergo and vertical grips help with mobility. Using a angled or folding grip completely cancels out the first-shot multiplier on the U-100 MK5, enabling accurate tap-fire and tight shot grouping in short bursts.


If iron sights are used in multiplayer, a rendering bug may occur whereas the sights do not show up for a few brief moments in a similar fashion the F2000 bug in the Battlefield 3 co-op mission The Eleventh Hour.
