[Marwan]

hi guys,
i recently bought a mares sten pneumatic from a friend of mine, it came with an 8mm 120 cm shaft, seems a bit long for the gun. Does anyone know the standard length of the spear for the sten 100.
cheers

cm 25 x Seac 30
cm 35 x Omer-Mares 40
cm 50 x Omer-Mares 50
cm 53 x Omer 56
cm 65 x Omer-Mares 70
cm 75 x Omer-Mares 80
cm 85 x Mares 90
cm 89 x Omer 96
cm 95,5 x Omer-Mares 100
