Beryllium Two Polish soldiers with the Beryl and Mini-Beryl. Both firearms are named after the element. Note the Pallad Grenade Launcher on the full size rifle. That accessory is named after another element, Palladium. If you’re wondering why the soldier kneeling is holding the magazine instead of the forward pistol grip, you’ll notice he’s against a wall. If he were to hold the forward pistol grip, his hand and forearm would extend beyond the wall and be exposed to enemy fire. More than likely not a real engagement since it looks like both guns have their blank fire adapters on.
