One of the areas where a lot of us lose time is on our rifle. Even if you can cycle the lever quickly, how you pick up and mount the rifle can cost you a lot of time over the course of a match.

This can lead to misses and extra time. You also need to watch how you discard the rifle, as this is another area where you can lose unnecessary time.
