Geissele Super 42 H2 spring and buffer kit

"The Super 42 Spring has a 15% stronger average return force than the standard buffer spring."

Try a regular spring and a regular ar15 magazine (aluminum Okay mag).

Do you have more forward and backward wiggle with the Duramags than a standard ar15 mag?
