I've been using my JG M41 (F6604) for a while, and I just thought that I want to add some accessories to it. So far, the only progress I've made is adding a Red Dot Scope in replacement for its stock carry handle rear sight. Basically, I want to put an angled foregrip on the hand guard but the hand guard it comes with has no rail. Is there a way to put rails on the hand guard? Or if you guys have better ideas for a custom M4A1, please let me know. Thanks! P.S. I'm thinking of just putting a Holographic Sight in case I don't find a way to add an angled foregrip on the hand guard.
