M3 Super 90 Upgrades

Folks,

 

Got a wild hair to upgrade my magazine tube spring to something a bit more 'heavy duty' and my follower to a high-visibility, non-binding one... any suggestions?

I'm currently getting my M3 upgraded at Briley Manufacturing. Check out their website:

If they don't have what you're looking for you can consult with their gunsmiths and they can customize anything for you.
