Duration: 10:09

The Ultimax Mark II, designed by Jim Sullivan, features a revolutionary 'constant recoil' system that significantly reduces felt recoil and muzzle climb, allowing for exceptional stability during full-auto fire. While its proprietary 100-round drum is effective, adaptations for STANAG magazines proved problematic due to wobble and reliability issues. The Mark II's fixed barrel could overheat, a flaw addressed in the Mark III's quick-change barrel system.

Quick Summary

Frequently Asked Questions

What is the 'constant recoil' system in the Ultimax Mark II?

The Ultimax Mark II's 'constant recoil' system, designed by Jim Sullivan, prevents the bolt from striking the rear of the receiver. This continuous movement minimizes felt recoil and muzzle climb, allowing for exceptional stability during automatic fire.

What were the main issues with the Ultimax Mark II's magazine adaptation?

Adapting the Ultimax Mark II to accept M16 STANAG magazines proved problematic. The modifications led to magazine wobble and reliability issues because the thin aluminum required for the adaptation was weakened.

How did the Ultimax Mark III address the Mark II's overheating issues?

The Ultimax Mark III variant introduced a quick-change barrel system. This design improvement allowed for faster barrel replacement, effectively mitigating the overheating problems experienced with the Mark II's fixed barrel during sustained fire.

What are the ergonomic drawbacks of the Ultimax Mark II's stock?

The Ultimax Mark II's stock is removable, but its mounting pins are notably fragile. These pins are prone to bending, which can make reattaching the stock difficult, especially under field conditions.
