While aiming down sights with this gadget, the bullets will land directly on the tiny circle of the sight, not above it. In other words, obscure your target with the small circle to it. While hip firing, the sight lines up relatively close to target, allowing easy hip fire shots at close range. However, sniper rifles overall suffer from an extremely large hipfire cone of fire; aiming down sights is highly recommended.
The Angled Sight can be installed along with another sniper scope, and does not replace the default sniper scope if installed without one.
