Some facts about Ksp 58D

 Pictures and information with courtesy of Anders Arvidson at the Swedish Homeguard

 The Swedish defence forces are making test with a modification of the LMG Ksp 58B. The large stock of Ksp 58 needs to be modified to better fit the Swedish army of today.

 The new modification is called Ksp 58 D and has following modifications:

  • Red dot sight (Aimpoint)

  • Collapsible butt stock or folding stock.

  • 100 mm shorter barrel

  • Better and shorter flash hider to reduce the length of the weapon and make the muzzle flash less, not to disturb the view of the shooter by night

  • Fluted barrel in order to reduce the weight and better distribute the heat of the barrel.

  • The carrying handle is shortened to half its original length. This was necessary to be able to have extended MilStd 1913 rail for sight systems

  • Cassette (pouch) for ammo contains 100 cartridges (before 50).

  • Gas regulator has only 4 settings (instead of 8). The last position is painted red and is intended for emergency use.

  • New ammo cases

  • New equipment bags

  • A Milstd 1913 rail system added. Half of the weapons has an adjustable rail - the others a fixed

  • Bipod is painted green

  • There is a sheet for protection / one side green other side white / summer & winter camouflage.

  • The weight of the MG is the same

  • The weight of entire system is 3 kg less


Colours for the LMG were 12 black and 12 green and at least one with different colour.

There are all together 25 pieces of these GP MG. They were finally tested in two different configurations during 2005 at P4 (Tank regiment No 4) before the final version will be spread throughout the Swedish Defence Forces.
