Mk3 Assistance
Hi Guys! Hoping someone can help me, I've recently acquired this Mk3 at an auction, matching numbers Lithgow manufacture. I am waiting on paperwork from police to be able to pick it up, but have been and inspected it a couple of times, pre & post purchase.
I can make sense of most things, the only exception being the sling stud in front of the magazine well, does anyone know why this would be there? You may need to zoom in on the photo a little, unfortunately these are the only photos I have until I can bring it home.
Thanks!
