Z-Grip compatibility issue

[Battle Popez0r]

My MAG: Z-Grip, RT Valve, LvL 10 bolt, some gas through fore-grip. Everything else is stock the body and other major componets. I really want to upgrade to the ULE warp body. what parts will i need to do this upgrade? I would love to use my Z-Grip but i realize that its quite old and AGD most likely dosent support it any more but if it fits its my first choice. Some one also told me that I had to pound out some thread or something for the ball detent. What do you know about this and the other questions I asked? any input welcome. Heres a pic of the curent gun.

All that you would need to change would be removing your twist lock assembly. It's the little silver thing in the rail in front of the front grip frame screw. Some come out easily, but as you've heard some take a little more encouragment;)
