The Fjord is based on L-39 anti-tank rifle with shortened barrel and the distinctive bipod removed. It has a gray metal receiver and wooden shoulder pad, cheek guard and grip. It has a large top-mounted box magazine, which is why the iron sights are located on the gun's side. The barrel is covered with a rusty shroud and is tipped with a muzzle brake.
- The name "Fjord" was chosen because it is a direct translation of the last name of Aimo Lahti, the designer of the real world counterpart of the weapon.
