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.

Perfect size for me!
Color: Black
I've had this bag for several months! It's in GREAT condition for the price that I got it for! I've had one maybe a couple stitches on the handle fray a little bit, but other than that it's holding up amazingly! Surprisingly it holds a lot, wallet, keys, small makeup bag, and a smaller bag for hair ties, pins, tampons and whatnot. It's very soft, the color doesn't fade! The material isn't hard leather, it's very maluable, making it fit wherever you put it, which is exactly what I was looking for. When this one eventually wears out, I'll 100% buy another one again because it's small and it matches every single one of my outfits!

Cute but cheaply made
Color: Black
I love this bag so much. However, I had to purchase twice because the first one broke due to the fabric on the inside catching on the zipper and when I tried to undo it, it ripped. The second bag still has problems with the zipper but it has stayed in good condition. The bag holds quite a lot and it’s really good. Overall I would say that bad is cheap but also lasts? Just be cautious of the zipper.

WORST PRODUCT I HAVE EVER BOUGHT- and I’m NOT picky.
Color: Black, Color: Black
DO NOT BUY. Genuinely the worst product I have ever bought. I’m not a picky person. But upon receiving this bag, I immediately felt iffy about the material of the bag. Then I opened it to get a whiff of a rancid fishy smell. As I’m not a picky person, and it was $20, I moved past these two immediate issues. My problem came on day 4 when the interior ripped. The material is so cheap it was not able to be sewn to be fixed. I was irritated, but was able to move on from even this. Day 6 of use was the final straw for me. The zipper got caught and completely stuck on the ripped material. While trying to wiggle it, the tab to pull the zipper came off. While again trying to get it open by hand, the zipper ripped completely open and part of the zipper track came off. This is THE MOST DISAPPOINTING ITEM I HAVE EVER BOUGHT. Absolutely DO NOT RECOMMEND. DO NOT GET THIS BAG. I don’t even want to give this one star.

SO MUCH SPACE AND IS SO CUTE
Color: Black, Color: Black
I LOVE this bag. To give you an idea, yeah duh it’s cute whatever. BUT let me tell you I brought this to an all day race event and fit my (large) wallet, 2 pairs of sunglasses, all of my lippies, AND NOT ONE BUT TWO FULL BOTTLES OF COKE!!! And it still zipped. Insane amount of space in this thing and it’s so cute too. 10/10 would recommend and I’m buying it in the khaki color too!
