If you can, get a retractable stock (This is why the C7A2 has a retractable stock), and sit it directly over your right lung. Not over your shoulder.
Your chest must be perpendicular to your rifle (People have the HARDEST time doing this, I have no idea why)
And bend your knees like your skiing down a hill.
The whole reason for everyone using retractable stocks these days is because in this stance which maximizes your armor profile, you can't see through your scope or iron sights worth a damn if you have a full stock
