M4 A1 foregrip rails...

So my JG M4 has no RIS rails on the foregrip, (as shown in the picture)http://www.airsoftpost.com/matrix-eagle-custom-lipoly-ready-m4a1-piece-barrel-full-tune-380450-p-29002.html
I have seen the rail itself that attaches to the holes in the bottom of the foregrip, but ive only seen it in the length for the m16, are they even avalible for the m4?

link doesn't work! i bet they do make them...and the M16 rails would probably work....

These were the one I was planning on getting, but My locale shop is hooking me up with something else. Yes, they're almost all this expensive.

o i was thinkin just a rail itself to attach to my stock grip

Ah. It IS possible, I've watched it been done before, But it really takes some work. If you're planning on putting an M203 on, you'll need to drill holes in a steel wedge and put it in between the rail in forgerip to even it out because other wise your M203 will be slanted upwards, as M4 foregrips are. Then you'll need to bolt/screw the railing into the wedge and the grip. Like I said, I've seen it done but it requires plenty of work to keep you busy.

no there are special rails that are made to go on these forgrips.... they attach to the holes in the bottom part of the forgrip. there are three or so holes in the bottom of the m4 (m16 style) forgrip.

Yes, I know what you're talking about, I'm saying you have to get a wedge if you put an M203 on.
