The Ultimax 100 LMG/SAW (5.56x45mm), designed and developed (along with its 100-shot drum magazine) from scratch in the late 1970's/early 1980's by Jim Sullivan (L. James Sullivan) and his design/development partner Bob Waterfield for then CIS of Singapore (now Singapore Technologies Kinetics Land Systems, a.k.a. ST Kinetics Land Systems), is considered by many small arms experts to be the best 5.56mm light machine gun/squad automatic weapon (LMG/SAW) in the history of the world. DefenseReview has been writing about the Ultimax 100 LMG/SAW virtually since our inception. And, in the last year or so, we've discussed the Ultimax quite a bit. In our article on Noveske Rifleworks Weapons packages, we discussed not only what's important about he Ultimax, but also how and why it's superior to the U.S. Army's current light machine gun/squad automatic weapon (LMG/SAW), the problematic/subpar FN M249 SAW. We also mentoned the Ultimax 100 SAW in two of our articles on the Auto-Assault-12 Shotgun (AA-12 Shotgun): our first-ever blurb on the AA-12, and our more extensive article on the AA-12 and FRAG-12 12-gauge armor-piercing grenade family, published subsequently.
The reason we bring all this up is because Vincent L. Deniro (CEO) and Brian Vuksanovich (Chief Engineer) at American Defense Management, Inc. (ADM) have developed a bunch of modifications to the Ultimax 100 MK3 for VT Kinetics/Vision Technologies Systems, Inc. (VT Systems, Inc.) to create the...

Ultimax 100 MK4. One of these modifications is a 4179 STANAG AR-15/M16 magazine adapter that allows the Ultimax MK4 to accept both 30-round AR-15/M16 mags and 100-shot Beta C-MAGs.
Author's Note: The original C-MAG was also designed and developed by Jim Sullivan. Before The BETA Company (a.k.a. BETA Co.) changed the TDP (technical data package) on the C-MAG, the original design's double-drum magazine body was made from a type of nylon, and the center feed portion (box mag portion) was made of steel and rise above the double-drum portion like it does now. Both of these material aspects were on purpose. Because the double-drum portion was made of nylon, the original C-MAG worked reliably without the need for any type of lubricant. In other words, it didn't require graphite powder lubrication to move the ammo/cartridges around the drums reliably. BETA Co. changed the nylon double-drum portion to a different material (a type of plastic/polymer) and changed the center feed portion to polymer/plastic, in the process making the center feed portion taller (due to the need to reinforce this part to prevent cracking/sheering during firing). One good thing the BETA Co. has done to the BETA C-MAG recently is to make the back plate of the C-MAG clear (Lexan), just like the latest factory Ultimax 100 drum mag (also 100-shots) back plate, so the operator can keep track of his ammo supply visually, during the fight.
The Ultimax 100 MK4 fires from the open-bolt, fires at a cyclic rate/rate-of-fire (ROF) of 400-600 RPM (Rounds-Per-Minute), and can be adjusted between these two rates by the operator. The MK4 can be had with a 13-inch barrel, side-folding buttstock, and Mil-Std-1913 rail system on top of the receiver (for mounting optics, lasers, etc.) and on the forend at the 3, 6, and 9 o'clock positions for mounting additional accessories (tactical white lights, lasers, vertical foregrips, etc.). Just like all versions of the Ultimax before it, the Ultimax MK4 utilizes the "Constant-Recoil" principle (invented by Jim Sullivan specifically for the Ultimax) which allows it to outhit heavier machine guns (chambered in the same caliber) on full-auto. "Constant-Recoil" reduces felt-recoil and muzzle rise and thus increases controllability on full-auto, resulting in more hits on target. This recoil attenuation/mitigation aspect makes the Ultimax the most contollable LMG/SAW in the world, even though it's also the lightest-weight LMG/SAW in the world.
Believe it or not, the Ultimax offers an 8:1 hit ratio advantage over the M16 rifle when both are fired offhand on full-auto side by side against multiple targets, including moving targets. When both weapons are fired from the bi-pod, the Ultimax offers a 2.5:1 hit ratio advantage over the M16. The box/drum mag-fed Ultimax 100 LMG/SAW will outhit the belt-fed FN M249 SAW and MK46 MOD 0/1 at 3-times the range, on full-auto, even though it weighs considerably less (9-10.1 lbs, depending on the configuration vs. a listed 16.75 lbs for the M249 SAW). The box-magazine/drum-magazine/double-drum magazine-fed Ultimax 100 MK4 is also much faster and easier to reload in a fight than the M249 SAW, especially in a dynamic, fluid situation like a running gun battle/firefight while the infantryman is firing on-the-move. In this situation, it's nice to be able to reload quickly and relatively easily on the move as well, which the Ultimax allows an operator to do. The Ultimax can be reloaded as quickly and easily as an assault rifle, since it's magazine-fed, rather than belt-fed. As it happens, the Ultimax 100 series is also significantly more reliable under adverse/combat conditions and high-round-count than the FN M249.
In fact, the Ultimax is so good that noted gunwriter Charlie Cutshaw, in his article on the Ultimax 100 MK4 for the latest issue of Special Weapons for Military & Police (SWMP), states that the Ultimax 100 MK3/MK4 makes for the best existing answer to the U.S. Marine Corps' (USMC) stated requirements for an "Infantry Automatic Rifle" (IAR). Defense Review wholeheartedly agrees. The Marines could certainly do a lot worse. Incedentally, the Ultimax 100 MK4 is the cover gun of this issue (#42).
