Just remember that firing a semi-auto is a somewhat violent event. A portion of the gas is used to eject the fired cartridge and the deflector changes the trajectory of the spent cartridge as it leaves the rifle. My Grendel AR cases show a more pronounced flat spot than my .223 AR cases. But the G also has more powder in it so it's ejection is more severe. It is a natural byproduct of shooting and the Velcro will definitely help.
