Z-RAM Firing Bolt + Powerkit.50 V2 for Umarex HDR50 TR50,  export valve,  Gen2 + Gen1 , 7.5j version 20-30J

 

Includes Powerkit.50 V2 + Z-RAM Stainless Steel Bolt
Output: up to 30 Joules

Take your Umarex HDR50 / TR50 to the next level with this high-performance combo! The Powerkit.50 V2 delivers massive output (20–30J), and the included Z-RAM Stainless Steel Bolt lets you skip the nightmare of removing the factory aluminum pin — which often breaks or gets damaged. Just screw the new pin into the steel bolt, drop everything in, and go. Easy install. Big results.

💡 Why this combo saves you stress:
Removing the original Power-Pin from the factory bolt is a major pain — it’s press-fitted, fragile, and frustrating. This kit solves that by giving you a ready-to-install steel bolt. Time saved. Nerves spared.

Definitely not worth the money you pay.
Size: 14 Ounce (Pack of 1), Set name: Standard
The dogs love them and they are great treats. The problem is for almost $20 a bag. You only get a fourth of the bag hole sweet potato strips. The rest of it is just the scraps from the skin. These get stuck in my dog’s gums and then their teeth and they’re hard to digest. I stopped buying them and went to another brand, unfortunately. I thought maybe it’s a fluke and the back got shook up, but I’ve ordered at least eight bags.

First shipment was quality
Size: 8 Ounce (Pack of 1), Set name: Standard
Initial delivery was impressive. No odor no additives and longer pieces. Second bag was full of short, burned pieces. Expense would be worth it, if quality control existed.
