For accurate shooting, don't let your barrel touch the barricade
John 'Shrek' McPhee emphasizes that firearm barrels must not touch barricades during shooting.

This is crucial for maintaining accuracy in tactical scenarios, especially when using red dot sights on platforms like the AR-15. Proper weapon handling and understanding ballistics are key.
