First you hold the rifle at the right side of your hip. Once in place you put your trigger finger in front of the trigger(finger must be straight). The hand you are shooting with must not hold the pistol grip or any part of the rifle. To fire you pull the rifle forward with the hand holding the front hand guard. If you do it correctly your trigger finder should come in contact with the trigger because the rifle is being pulled forward. Once the rifle starts firing keep pulling the rifle forward with your hand that is holding the front of the rifle. Rember one must keep pulling the rifle into your straight trigger finger, you should not move you trigger finger into the trigger. This might seem a little weird so I included a page with a animated gif of me bump firing and a few videos of some burst firing.

Once you get good enough to do it from the hip you can move on up to the shoulder bump. View the shoulder bump video to get an idea of how it is done. And yes the video is of me with a STOCK SAR-2.

To watch the videos you must right click on the link and select "save target as". Once the video is saved to the hard drive double click on the video file to watch. You will need the latest version of quick time and DIVX to view the clips.
