As far as I know, German Sport Guns doesn't offer their products without barrels.
A .50 caliber machine gun, such as the M2 Browning, typically weighs around 84 pounds (38 kg) without the barrel. However, the weight can vary slightly depending on the specific model and configuration. The barrel itself adds significant weight, so the overall weight of the weapon with a barrel is much higher.
When it rains or there is a flood it spreads out its roots and absorbs as much water as possible without bursting.
100-400 USD
Without more of a description; 10-100 USD or so
