It seems that the Ofna body is harder to get than I thought. 2 Store already told me that they dont stock it and they need to order from Ofna. Anyway, I might be heading the Slayer Body/suspension after all.
On the other hand I got my hands on this items. Finally I was able to get to his listing before it got sold again....
item 1
Item 2
