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.

Why would you want anything else?
Size: Standard (20" X 26"), Color: 02 - White, Number of Items: 2
I don’t know why anyone would want pillow cases that don’t fit the pillow. These are “envelope” style meaning the pillow tucks inside them for a perfect fit—no “leftover” pillowcase sticking out on the end. They’re very soft and cooling and I have so far bought ones for every bed in my house and will be getting more as extras. Highly recommend!

Very soft
Size: Body (20" X 54"), Color: 06 - Sage Green, Number of Items: 1
The color was perfect. It’s very soft. The only thing that I really don’t like is the finish of the opening, it would be better with a zipper closure.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!

Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉
