This variant comes with a 120-round drum magazine and a bipod. It offers more rounds in the magazine, and it's deigned for stationary use. To unlock it, you need to get 300 kills with the Hellriegel 1915 Factory, and 25 kills with AT Mines.
Medic Selbstlader 1906 Sniper
This version of the Selbstlader 1906 comes with a sniper scope and a bipod. It offers increased range for an already accurate weapon. You need 300 kills with the Factory variant, and 25 kills with rifle grenades to unlock it.
Support Huot Automatic Optical
This variant includes improved sights and a foregrip. It's designed for on-the-move combat and offers greater control over recoil. To unlock it, you'll need 300 kills with the Low Weight variant, and 25 kills with Limpet Charges.
Scout Martini-Henry Sniper
The already very powerful Martini-Henry gets a sniper variant with a long-range scope and a bipod. As you'd expect, this could make the weapon more effective at further ranges, if for nothing else than replacing the iron sights. You need 300 kills with the Infantry variant, and 25 kills with the bayonet charge.
