Pak40 recoils?

[eliminater]

Just started to create a Pak40, when I cam to the moving parts I became unsure:confused:

It seems to be rails where the barrel is moving on. But I need to be sure before I go on. Watched a few videos but cant se so much, to much smoke when firing

so how does it recoil when firering?

See the red marks on pics what I think would be a trail

[Big Red 11]

Common sense tells me that those are moving parts that are attached to the barrel assembly, and are meant to keep the assembly on the rail.

Here's a little sketch, looking from behind, that I threw together on paint:

If you ignore my amazing abilities and look at what I drew, the red is the barrel, the blue is the rails, and the black is the parts you highlighted.
