Okay. For a field stripped pic of an Ultimax, please tune your browsers to:

Now, I have used and fired the Ultimax, although its been a number of years since I last did so. The Ultimax can be just as accurate, firing single shots, as an M-16, and probably more so when firing burst. This accuracy is due to a number of design features.
The first is simply because it has a longer barrel than a rifle like an M-16. The second is that the long recoil system and long return spring of the Ultimax gives it a smoother action, and makes it easier to control. Other factors include its weight, its a bit heavier than an M-16, and that it has a foregrip and bipod, which makes it very nice to fire from prone. A skilled gunner can easily fire of single shots accurately, and have very good burst groupings.
The open bolt action and movement of the bolt is actually quite light, and it is of a rotating bolt design, also like the M-16.
Lemme think... okay, for those of you who are familiar with an M-16. When you an empty M-16, the bolt catch device engages, holding the bolt in the open position. Pushing down on the device causes the bolt to spring forwards and lock. Now, the force of this movement on the M-16 is actually more than the force of the bolt movement in the Ultimax. Thats becasue the Ultimax uses a lighter bolt and narrower, but longer spring than the M-16.
the Ultimax isn't a perfect weapon though, by any means. It's carry handle is too far forward of the centre of gravity, making it akward to carry via the handle. The 100 round drums are such a hassle to load that we almost never used them for training. The early mk.1 versions were junk, with blobs of bad welding and prone to jamming, probably because of the shoody construction. The mk.3s, on the other hand, were very nicely machined, with no welds at all, and functioned well. |
