Back in July we looked at polymer belt links developed for PK series machine guns made by a Ukrainian company, the Kharkiv Plant of Personal Protective Equipment – who trade under the name RAROG. Development of the links began back in 2015, and since the Russian invasion in February production of the links has increased.

Unlike the classic metal 7.62×54mmR belts, the new polymer belts are disintegrating – meaning once the round held in the belt link is fired and the next round is loaded it falls out of the gun just as with NATO standard disintegrating belts. This has the advantage of there are no longer being a long empty section of belt trailing from the gun.

One question that was regularly asked in the comments of the first video was – can the links not be made from a biodegradable material?  

Speaking RAROG they made it clear that there is currently no possibility of using biodegradable materials to make the belt links as they would not be strong enough for them to work properly. Unsurprisingly, the reality of the situation means a reliable, durable product that won’t fail, with dire consequences, during a firefight is a much more important consideration.

The company relocated from Kharkiv to Lviv following the invasion but quickly re-established manufacturing and tell me that on average 100,000 links are shipping per month, although they have the capacity to produce far more. They are often shipping with their fabric belt bags. The bags and links are largely privately purchased by Ukrainian combatants.
