Z-RAM Z-Extension/Chamber Kit for FSC/TCP T8.1 T9.1 (Complete!) (B-Stock)
Note – B-Stock Item:
This item is sold as B-stock. It is fully functional, but the thread on the chamber part differs slightly from our standard production. As a result, you cannot combine these parts with identical components from other batches.
Only the ASA to Chamber Adapter and the Z-Extension are compatible with other chamber adapters. The thread deviation affects the chamber only. Please note that standard O-rings will not fit this version.
Everything works perfectly – that's why it's offered at a discounted price.
