The older Z-RAM stainless-steel firing-bolt assembly is listed for First Strike FSC, PepperBall TCP and Tiberius T8.1/T9.1. Its compatibility with FSC XP remains unconfirmed; that is an evidence gap, not a finding of incompatibility.
What “complete set” means in this listing
The contents list names a steel chamber, steel plug, stainless-steel firing bolt, Power Pin (Export Valve), firing pin, two stainless-steel screws and three named groups of O-rings. These are listed package contents, rather than a statement that every part of the marker is supplied.
The product is an aftermarket Z-RAM set. Its description explicitly says it is not an original First Strike part. First Strike, PepperBall and Tiberius identify the named platforms; they should not be collapsed into the manufacturer of this Z-RAM assembly.
The FSC XP distinction
The unconfirmed status applies to the older assembly and its individual components. An assumption about a complete set is not evidence for every component separately.
A separate product, the ASA Tuning Chamber Extra Long, explicitly names FSC XP. Its confirmation belongs to that chamber and does not establish the older assembly’s FSC XP status. The two statements can coexist without declaring either product description false.
