Would this be a good piece of hop up rubber? http://www.airsoftstore.ca/index.php...roducts_id=164
They say it's their "go-to" rubber for standard AEG buckings, but I'm a bit concerned of the 50D (50 degree) rubber, which seems a bit soft for a higher FPS airsoft gun like the one I have (if it's anywhere around the 393 FPS rating on the box).
Would it be necessary for me to replace the hop-up rubber though? My CA M15A4 airsoft gun already has decent accuracy in its stock configuration, IMO, so maybe the hop-up is still good (the gun's not even a month old):
