ICS Metal Body?
 

Is ICS M4 metal body easy to find?
I know I can try to search in AV thread, I just wondering. Met VOR last Friday, and waiting AV to be activated. :cool:

They show up occasionally. I picked one up not too long ago. But they don't show up too often, and they're always used.

actually can I use other brand metal body?

No, you can not use other metal body. It must be ICS specific. The lower maybe able to use other brand but need some mod but the upper is for sure that you can't use other brand.

No, the lowers of other brands won't fit either without significant (as in probably not even worth it to try) modification. If I remember correctly, the ICS body is a bit wider.
