This is used for bolt action sniper rifles like the M24 and the L96A1
So here's the technique
After you fire a shot quick double tap the "Q" button which will skip to your previous weapon and back again skipping the animation of pulling the lever back and forth therefore making it a faster way to shoot again.
Note: When you respawn go to your melee weapon and back to your sniper so that when you press Q twice that's what it will go to.
