Many people don't know it, but there actually is a short carbine version of the SVT-40. It's called ABT-40 and is very rare.
But as you can see in the photography, they exist!
This also includes a world-model as you can see in the pictures.
It also includes new shooting and reload sounds. Choose between two different shooting sounds. One shooting sound is named "m1carbine_shoot2" and if you want to use that, just remove the "2".
