Z-RAM Upgrade Package for Umarex HDR50 TR50 (35 Jo. 12g CO2)

 

Looking for a clean and effective upgrade path for your Umarex HDR50 / TR50? This custom package includes everything you need to push your marker to 35 Joules using a standard 12g CO₂ cartridge – including power-boosting internals and a tactical grip for better control.

The included Z-Extension, tuning barrel, and barrel cover work together to deliver consistent performance, while the angled foregrip improves handling and adds a tactical look. A set of Z.50v2 steel projectiles rounds off the package, so you're ready to go.

 

Included in this package:

✔️ Z-Extension – boosts power by increasing chamber volume
✔️ Tuning Barrel with Standard Extension – optimized for .50 cal accuracy & range
✔️ Barrel Cover – clean look, protects the barrel
✔️ Universal Angled Foregrip – for improved handling and stability
✔️ Set of 6x Z.50v2 Steel Projectiles – high-impact stainless steel ammo

⚠️ Marker not included. 

 

Performance:

⚡ Approx. 35 Joules with 12g CO₂
🔄 About 6 high-power shots per capsule
📦 Optional: Use with a modify pin (sold separately) for ~10 shots at ~30J

 

🚧 Important Note:

This setup uses the stock HDR50 body. In order to fit the Z-Extension, you will need to cut an opening in the rear of your marker housing. Without a compatible Z-RAM body kit (e.g. ZDR50, ZDR50v2, Tec9), the extension won't fit flush. This modification is purely external but requires precision and care.

 

💡 Note: For best performance, we recommend adding a suitable Power Kit that matches your specific marker model.
This is not included in the package, as there are different versions for each model.

The Power Kit provides additional power and ensures better sealing under increased pressure and gas flow – a perfect addition to your upgrade components.

Excellent for heavy chewers
Excellent toy for heavy chewers like malinois! The rope makes it easy to throw farther. Good amount of bounce as well. Definitely need to supervise as it could be a choking hazard for larger breeds.

Rope breaks toy breaks, buy it anyway?
3 stars. 4 stars during the 5 months it worked. 2 Star now. The rope bites through easily & often. I could hobble the rope together the first 5 months (see how it's shorter) now toy is a dud. Durability 1 Star. Took my 6 month old puppy a few minutes to do this. You see, she chewed threw it a few times and I was able to re-tie it until I ran out of rope. She DID love to do the puzzle- carrying it around, banging it on the ground repeatedly, tugging the rope gently up and down, holding the rope while shaking the ball like a pendulum side to side, rolling it with her paws like a cat, holding the rope with her teeth and banging the ball into various objects around the room trying to dislodge Stella and Chewy Meal Mixers... She's very clever and not at all a brut. I would give this to her for ten or fifteen minutes before bed. She still likes it and it still sort of works? She can no longer pull up and down on on the rope or carry it or around or bang it against various objects. So, you basically have a ball now with treats that can super easily fall out. You can just give your dog a regular ball with no hole and throw a handful of treats on the ground. I DO recommend buying this though. My dog loves it.

Greatest toy for GSD!
My German Shepherd LOVES LOVES LOVES this thing. I’ve purchased about 5 of them, not because they don’t last (they do), but so we can have them everywhere (one in each car, the backyard, the front yard, the house…). The string makes them so easy to throw far and you don’t have to handle a sloppy foamy tennis ball. And it’s great for playing a little tug. All in all, a winner of a product!

Good Toy Reward for Training
Size: Medium, Size: Medium
A great non-food reward for dog training and play! It’s the perfect size for my German Shepherd and the tie makes it easy to carry and play tug. It’s also been very durable for her sharp teeth!
