Currently, the X7 has only a small number folding stocks that can truly be considered milsim. The x36 folding stock from Tippmann/SO, the PDW folding stock from Lapco, Tacamo's CQB folding stock, and Trinity's Foldable stock with shoulder support.
In our opinion, only the tippmann, lapco, and tacamo folding stock truly look milsim, though the trinity one isn't far off. We wished to add yet another to that small group, and introduce our G36c folding stock. We have observed that many scenario/milsim owners of the X7 that have spent alot of money to buy the tippmann/so "G36" parts for their markers, were very dissatisfied with the lack of a proper g36c stock. So, we have met that need.
