While adjusting the windage on the front sight of the M240, how many noticeable clicks indicate a full revolution?

The correct answer is based on the design and mechanics of the M240's sight adjustment system. In the case of the M240, a full revolution of the front sight adjustment typically consists of eight distinct clicks. This means that as the shooter adjusts the windage, each click represents a small, precise movement that contributes to the overall alignment of the sight.

Understanding the number of clicks in a full revolution is crucial for accurately zeroing the weapon. Each click allows for measured adjustments, which is important for compensating for wind drift during firing. Knowing that eight clicks constitute a complete revolution helps shooters make systematic adjustments rather than guessing how much they have moved the sight.
