    I recently purchased a JG M4 S system rifle. Pull it out of the box, its a bit heavy. Ok, no problem.. Ill swap the rail system to a bit lighter one. Not happening. The upper reciever rail is part of handgaurd system. Anyone ever modify, or swap this system out?? I absolutly love the rifle, just would like it to be a bit lighter.

    I actually built my current gun off of a S System. Here is a step by step:
    1. Buy new upper receiver
    2. Buy new barrel
    3. Buy RIS of your choice.

    The S System is one of the crappiest designs I have ever encountered. Zero upgradability.
