Z-RAM Firing Bolt + Powerkit.50 V2 for Umarex HDP50 TP50,  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 HDP50 / TP50 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.

Work perfectly- keys, watch, wallet and colognes, etc
Color: Black
For the price- this thing is beautiful. It is high quality- and appears higher quality than the price would make it seem. I originally purchased one that "appeared" to be wood (same design) but ended up being cheap injection molded looking plastic. There is absolutely no assembly- so just pull it out of the box, and fill it up. Has space for wallet and keys, and small objects. Little drawers are lined and high quality as well. Great side piece if you are a fragrance collector. If not, there is plenty of space for the normal guys colognes- with room left over for anything else you would put on a 2" shelf. Stop reading and add it to your cart already.
