Here is one for your review, possible no recoil.

I cannot see any definitive instances without recoil. Middle of demo Looks like recoil when player fires at automobile and at end when player fires at building. Not so much in the beginning when firing while moving sideways. Thank you for the report.
Below is an example demo of a different player with a definitive no recoil and wallhack using the same weapon with a suppressor. You can easily see the no recoil instances when player is aiming straight at target while firing weapon without any movement.
