Get DragonSkin, bends enough to get the shouldering just right in any position
Ok it might be a bit expensive for airsoft, and too for others. Regular shouldering on the chest and without chicken wings works very well. If you have a stock with a patterned butt plate like an M4A1 stock, VLTOR EMOD, etc it helps a bit. My trainees like to put it more or less on the edge of a plate to have an additionnal support.
