Semi-Automatic Heavy Anti-Material Rifle (HAMR) [ 1990 ]

The Gepard M3 was more or less an enlarged version of the earlier Gepard M1 / M2 AMR models though now chambered for the massive Soviet 14.5x114 cartridge.

To ring even more performance from the Gepard line of Anti-Material Rifles (AMRs) beginning with the single-shot Gepard M1 and evolving into the semi-automatic M2, Hungarian engineers turned to a new AMR centered around the ultra-powerful 14.5x114mm Soviet heavy cartridge. The result became the Gepard M3 which became one of the most powerful heavy rifles in all of Europe offering gains in both engagement ranges and accuracy. It proved a popular addition to the Gepard line seeing adoption by several armies and special forces groups worldwide.

The M3 was more or less a dimensionally larger version of the semi-automatic M2 model. A hydropneumatic recoil system (akin to an artillery piece) aided in the inherently violent recoil action produced when firing such a large cartridge. A larger muzzle brake was also added to improve efficiency. Overall length of the weapon measured 74 inches with a weight nearing 44 pounds. The semi-automatic action remained so feeding could be through a 5- or 10-round detachable box. However, this box was positioned next to the pistol grip and thusly favored right-handed shooters.

While the original Gepard M1 could penetrate armor up to 15mm at range, the Gepard M3 increased this value to 25mm of armor thickness. Beyond its usefulness in engaging light armor and protected infantry elements, the M3 was sufficient in bringing down low-flying helicopters and the like.©MilitaryFactory.com
