Ultimax 100

The Ultimax 100 was developed by Chartered Industries of Singapore (CIS) in the late 1970s as a indigenous Light Machine Gun for the Singapore Armed Forces. CIS was eventually merged into Singapore Technologies Kinetics (STK). There are seven models of the Ultimax 100:

• Mark 1 was a pre-production variant with a quick detachable light barrel that proved unwieldy.
• Mark 2 was the First Production gun with a fixed barrel and a carry handle located at the center of the gun.
• Mark 3 updated version with quick detach heavy barrel, different carry handle. This version came in two types, the standard and paratrooper length.
• Mark 4 is the updated version of the Mark 3 that was developed for the US Marine Corps trials of 2007. Amongst other details it has rails on the top of the receiver, it can take STANAG magazines, and has a skeletonized folding stock.
• Mark 5 is an updated Mark 4 with side-folding polymer stock, Picatinny rails, and STANAG magazine well for box magazines and 100-round Beta C-Mag drums.
• Mark 8 is an updated version with a folding, retractable buttstock with adjustable height. It is compatible with various magazine types such as STANAG magazines, SAR 21 type box magazines, 100-round Beta C-Mag drums, and Ultimax 100 drums.
• Mark 9 is an updated model with a new handguard and buttstock, and a dual-feed capability, accepting both STANAG magazines and M27 ammunition belts.
