When you stand or crouch without moving and pause firing momentarily, the four crosshair lines close together into a single pinpoint red or white dot. When FSA is active, your next shot travels with 100% mathematical precision to the exact center of your crosshair with zero random bloom spread.

Yes. Jumping or tactical sprinting completely disables FSA and expands your weapon's bloom cone to its maximum angle (up to 4.5° spread), making long-range hits entirely reliant on random RNG.
