Leopard 2A4 1:6 Scale Weapon and Weapon Mount

[PhilC47]

Good Morning All, I am purchasing a 1:6 Scale Leopard 2A4 soon to be released from Armortek in the UK. I have been researching the weapon station and mount and I am looking for assistance as I would like to make to suit 1:6 scale, my question is what size should I be looking for? The information that I have that it is a roof mounted machine gun, MG3 7.62mm x 51. I would be extremely grateful for any assistance and also any other additions or suggestions that members may have? Thank you in advance, regards Phil
