Z-RAM’s +24-Joule upgrade package for First Strike FSC and PepperBall TCP concentrates on steel internal components, Z-MAG equipment and chamber-extension parts. Its title advertises an increase of 24 Joules, whereas the separate 75-Joule bundle advertises up to 75 Joules of total energy with a 20g threadless CO₂ capsule. The practical purchase difference is the delivery list: the 75-Joule offer adds barrel equipment, while the +24-Joule package includes a standard-length firing pin and three listed projectile weights.
Both offers also name the separate Tiberius T8.1 and T9.1 models. For an owner comparing these bundles, the useful question is which group of supplied parts matches the equipment already owned. The numbers in the names do not describe two results from an otherwise identical comparison.
What +24 Joules means beside a 75-Joule headline
The plus sign in the smaller package’s title presents 24 Joules as a claimed gain. Its current description does not define one baseline marker configuration and test condition for that figure. The 75-Joule description is more specific about its claim: it states up to 75 Joules using a 20g threadless CO₂ capsule.
The figures have different meanings and no common defined test baseline, so their difference is not a measured advantage of one bundle. Gas supply, valve behavior, chamber, barrel and projectile work together; the supplied PowerPin is already part of each complete offer.
The contents that change the purchase
| Included group | +24-Joule package | 75-Joule CO₂ package |
|---|---|---|
| Steel internal parts | Steel chamber, plug, firing bolt, standard-length firing pin, PowerPin and stainless-steel set screw | Steel chamber, plug, firing bolt, PowerPin and stainless-steel set screw |
| Chamber-extension parts | Z-Extension, reducer/cap, housing stopper, extension cap, O-rings and screws | Z-Extension, reducer/cap, housing stopper, extension cap, O-rings and screws |
| Z-MAG equipment | Eight-shot frame, MagMode, Belt Cover and three capsule spacers | Eight-shot frame, MagMode, Belt Cover and three capsule spacers |
| Barrel equipment | No barrel, barrel extension or barrel cover named in the delivery list | 160mm steel .684 barrel, one 100mm steel sniper extension and 72mm barrel cover |
| Projectiles | Six each at 8.5g, 10g and 9.5g | Six each at 10g and 9.5g |
The table compares what the listings actually name. In particular, the standard-length firing pin is a separate entry in the +24-Joule package; it is not another name for the PowerPin. The 75-Joule bundle’s longer delivery list does not mean it contains every item or projectile selection in the other offer.
What the steel and chamber parts contribute
The +24-Joule description emphasizes original Z-RAM parts and V2A stainless steel. Its steel chamber, plug and firing bolt make material and durability a substantial part of the purchase, alongside the performance claim. Z-RAM’s chamber presentation explains the change from an aluminum chamber to a CNC-machined steel construction, with durability as its central benefit.
The chamber and plug form part of the gas chamber assembly. The firing bolt, standard-length firing pin and PowerPin are separately named internal components, so a buyer checking an existing parts collection should retain those distinctions. The PowerPin and standard steel pin guide covers their different product purposes.
The Z-Extension concerns chamber volume, while the reducer/cap, housing stopper and extension cap are the accompanying connection and closure parts listed in both bundles. These small components help explain why a package comparison should include more than the chamber itself. Increased volume can change how much gas is available during a shot, but volume alone does not establish the resulting energy.
Z-MAG is already part of both offers
Both packages list the eight-shot Z-MAG frame, MagMode insert, Belt Cover and a three-piece spacer set for 8g, 12g and 16g capsules. The same Z-MAG supports 8g, 12g, 16g and 20g threadless CO₂ capsules on FSC, TCP, T8.1 and T9.1. There is no different capsule-size magazine product to select for each of those sizes.
Z-MAG fits flush on FSC and TCP. On T8.1 and T9.1, the visible gap at the bottom of the grip is cosmetic and does not restrict the magazine to smaller capsules. The +24-Joule delivery list separately labels its Belt Cover as FSC-specific; that accessory wording should not be mistaken for a restriction on the Z-MAG itself. The Z-MAG fit and capsule guide explains the shared magazine and the different appearance.
For the shopping comparison, this means the magazine frame and MagMode are already accounted for in both bundles. They are useful included items when you need them, but they do not distinguish the +24-Joule package from the 75-Joule offer.
Barrel equipment and projectile selection are different benefits
The 75-Joule bundle includes a 160mm steel barrel with a .684 bore, one 100mm steel sniper barrel extension and a 72mm barrel cover. The extension is barrel equipment; the cover is the exterior protection and appearance accessory. This group is the clearest extra purchasing scope in the 75-Joule offer.
The +24-Joule package instead lists six 8.5g Z.68v2 projectiles as well as six 10g Z.68v2 and six 9.5g Z.68s projectiles. The 75-Joule offer lists the latter two groups. These quantities explain a real difference in the box without turning projectile weight into a new output prediction.
Match the bundle to the parts you actually need
If barrel equipment is already covered in your existing collection, the +24-Joule package is the more focused list to compare for internal parts, chamber-extension equipment and Z-MAG. If those groups and the listed barrel equipment are all wanted, the 75-Joule offer brings them together. This is a comparison of purchasing scope; the package names alone do not establish an energy difference for your marker.
The 75-Joule listing explicitly excludes the marker, and the +24-Joule delivery list describes upgrade parts rather than a complete marker. Check the exact named platform as well: neither offer’s FSC wording supplies confirmation for the older steel assembly on FSC XP. That compatibility remains unconfirmed, which is different from saying it is incompatible.
