1. Spawn m14, shoot, look at the trigger (not moving)
2. Find some hill so when you lay down you're lying NOT parallel to the horizon, you have to have M14 and Acog x4 attachet and be in scope mode (have to be like this, look at the picture)
Now start shooting and see how scope begins to twitch (first straight up from recoil (90 deg to the ground) than goes back to the side)
