Z-RAM advertises up to 75 Joules with a 20g threadless CO₂ capsule for its complete upgrade bundle for the First Strike FSC, PepperBall TCP and listed Tiberius T8.1/T9.1 models. That is a stated total-energy figure for the complete offer, not a 75-Joule increase from a single part. The bundle combines steel internal components, barrel equipment and a Z-MAG package; the marker itself is not included.
The offer brings performance-oriented steel internals and barrel equipment together with the Z-MAG magazine system. The valve assembly governs gas release, the chamber and extension provide gas space, and the barrel equipment belongs to the complete shooting configuration. Steel construction and the magazine’s supported capsule sizes add material and practical benefits beyond the energy headline.
What the 75-Joule figure tells you
The product description places the advertised figure alongside a specific gas condition: a 20g threadless CO₂ capsule. Keep that condition attached to the number when comparing offers. It does not mean that every capsule size or every individual marker will produce the same result.
CO₂ behavior depends on temperature and on the balance between liquid and vapor in the supply. The valve, chamber, seals, barrel and projectile also form part of the overall system. That is why neither capsule capacity nor the presence of one tuning component provides a separate guaranteed energy value. The package figure is a seller’s performance claim, not a measurement made for this guide.
The package presentation introduces the offer, while the accompanying component and test material explains its different parts. For the two advertised gas-system figures, see the 75-Joule CO₂ and 95-Joule HPA package comparison.
The steel components are a substantial part of the bundle
The delivery list names a steel chamber, steel plug, steel firing bolt, stainless-steel set screw and PowerPin. These are not alternative names for the same component: the chamber and its plug belong to the gas chamber assembly, while the bolt and pin are separately listed internal parts.
In its steel-chamber presentation, Z-RAM explains the move from an aluminum chamber to CNC-machined steel and describes the construction as a durability-focused upgrade. That gives the material choice a purpose beyond appearance.
The bundle also lists a Z-Extension, reducer and cap, housing stopper, extension cap, and an O-ring and screw set for the named assemblies. The extension concerns additional chamber volume. More volume alone does not determine output: the available gas and the way the complete valve system operates still matter. These are supplied components of the advertised package, not a list of extra purchases.
Barrel equipment and included projectiles
The CO₂ bundle contains the FSC steel barrel, one 100mm steel sniper barrel extension and a barrel cover. The delivery list distinguishes the barrel equipment from its cover, making it easier to compare the package with equipment you already own.
Six Z.68v2 projectiles at 10g and six Z.68s projectiles at 9.5g are also listed. Their inclusion gives the bundle two named projectile types with different listed weights.
If you already have a barrel, extension or some of the internal parts, compare your existing equipment with the actual delivery list before choosing the full bundle. A complete package is convenient when its contents match what you need; its headline alone is not a reason to buy duplicate components.
What the Z-MAG portion adds
The package lists an eight-shot Z-MAG frame, BeltCover, MagMode insert and a three-piece spacer set for 8g, 12g and 16g capsules. The same Z-MAG supports 8g, 12g, 16g and 20g CO₂ capsules with FSC, TCP, T8.1 and T9.1. You do not select a different magazine product variant for each capsule size.
Its fit is flush on FSC and TCP. On T8.1 and T9.1, the small visible gap between the grip and magazine base is cosmetic, not a restriction to the smaller capsule sizes. The Z-MAG capsule-size and platform guide explains that distinction in more detail.
The 20g condition attached to this bundle’s energy claim should not be confused with the magazine’s broader capsule compatibility. Compatibility answers which sizes the magazine supports; the performance claim describes one stated package condition.
The HPA bundle is a separate alternative
The second product card below is the separate HPA package, not an additional purchase needed to complete this CO₂ bundle. Its delivery list includes bottle-and-stock equipment, an ASA-to-chamber adapter and three sniper barrel extensions, rather than the single 100mm steel sniper extension in the CO₂ offer.
The alternative therefore changes the supplied equipment as well as the advertised gas format. Compare the complete delivery lists with what you already own before choosing between them.
Check the exact platform before ordering
This offer names FSC, TCP, T8.1 and T9.1. A shared family resemblance is not a blanket approval for other models or later generations. In particular, the older assembly’s compatibility with FSC XP has not been confirmed; that is not a claim that it is incompatible.
For a buyer seeking the broad CO₂ upgrade, compare the advertised performance and exact model coverage first, then check the steel, barrel and Z-MAG equipment against parts already owned. The complete package brings those functions together without requiring duplicate component purchases.

Z-RAM Upgrade Package for FSC TCP T8.1 T9.1 (95 jo. HPA !)
A separate HPA package with different barrel and bottle-and-stock equipment, advertised at 95 Joules. Compare it as an alternative format, not as an additional purchase required for the CO₂ bundle.

Z-RAM’s historical FSC film examines the nominal 10g Z.68v2 and reports chronograph series under its original conditions. The bundle also lists a 10g Z.68v2 group, making the projectile discussion relevant; the older film is not a test of today’s complete 75-Joule bundle.
