Ive seen some threads on here hit on the topic but never any oppions on which one members prefer.

Polymer or Metal...what would you chose and why ?

Would you replace the metal 416 ejection port cover with the mr556 polymer one ?

I don't see anything wrong with a polymer cover. For the simple job it does, cover the port and pop open when the bolt is cycled, I can't see that polymer wouldn't do as good a job as metal, especially on a piston gun.
