Earlier this month Popular Mechanics published an article I wrote about GRaft, a Ukrainian company which has manufactured belt boxes for almost every type of machine gun being used by the Ukrainian armed forces.

While belt boxes might not seem like the most exciting pieces of military equipment, they’re no less vital than the guns they’re paired with; the boxes are essential for storing and carrying ready-to-use belts of linked ammunition, and they allow machine gunners to move around unencumbered by hanging belts that can become tangled.

GRaft initially designed and manufactured furniture including benches and tables but with the full-scale Russian invasion in February 2022, they have since turned their attention and skills to belt boxes. With machine guns being transferred to Ukraine by a plethora of different countries this has led to a wide variety of machine guns entering service with the Ukrainian armed forces. In many cases the machine guns transferred to Ukraine are often without enough belt boxes.

I spoke to one of GRaft’s engineers who explained that their impetus to begin designing and manufacturing belt boxes came from friends’ experience with old boxes for PK-pattern machine guns. He explained that the old aluminium PK boxes had seen decades of service and there was a general shortage of them.

GRaft began work on their PK box in April 2022 and within a month had a design ready for manufacture. GRaft refined its designs based on direct user feedback and soon began working on belt boxes for other weapons ranging from 14.5mm KPVs to 5.56x45mm and 7.62x51mm FN Minimis.

GRaft kindly shared some videos from their workshop showing how the belt boxes are fabricated. They use laser cutting to cut sheet metal into blanks which are then shaped and riveted and spot welded into their final form. They work with a small paint shop that then powder coat the boxes.

The company also developed 75 and 100-round boxes for the FN MAG/M240, the 100 round box was designed with an angled wall so the mass of the belt sits closer to the weapon’s center of balance, improving the weapon’s handling. Similarly they have also begun producing boxes for 7.62x51mm MG42-pattern machine guns. Their goal, the engineer told me, is “satisfied machine gunners” but really they’d like to get back to producing furniture.
