Umarex HDR50/TR50: 520 FPS and About 77 J with HPA — Part 3

This is a sentence-close edition of Z-RAM’s original video. Product availability, package contents, links and performance statements retain the context of that recording.

Umarex HDR50/TR50 Part 3: from the CO2 setup to HPA

Welcome to Z-RAM’s YouTube channel. Today, Z-RAM presents Part 3 of the HDR50 series. It will link the first two videos above. Please check them out before continuing here so you know what has been done with this setup.

This setup reached 35 J with a 12 g CO2 capsule. The chamber block was removed, and the valve was removed completely. There are two Z-Extensions here, a tuning barrel, the sniper extension and the standard extension of the tuning barrel. As already stated, the result was about 35 J.

For those for whom this setup is still too big, Z-RAM now has the ZDR50 V2 valve, with which you can get to 38 J even with the normal extension. A short setup with 38 J: that is what you can achieve here with this valve. However, you also need this case, because otherwise the valve will not fit. Down here, you can even screw in 25 g CO2 capsules. Z-RAM will link the video above.

Today’s video will turn this setup into a sniper setup. Let’s get right into it.

Umarex HDR50/TR50 adapter, bottle and barrel extensions

First, the standard extension is unscrewed so that the whole thing is a little more manageable. Then these two Z-Extensions are unscrewed, and the ASA-to-chamber adapter is screwed on here. With the adapter on, the bottle will be screwed on now.

This is the bottle; its regulator is at 1,100 PSI. There is also the buttstock adapter on the bottle.

The bottle is now screwed on. Here is the tuning barrel, here is the sniper extension, and this is the standard extension of the tuning barrel. First comes the tuning barrel, then the sniper extension and then the standard extension. Now a second sniper extension will be added. You can screw on as many sniper extensions as you like. There are now two here.

Finally, it is time for the standard extension, although you could also screw the silencer on. Z-RAM will not do that now, but you can order it in Z-RAM’s shop. The standard extension is now being screwed on.

Umarex HDR50/TR50 covers, grip and scope fit

Z-RAM then takes a second barrel cover. This one is for the HDR50, and this is the barrel cover for the ZDR50. Of course, you can also use a second HDR50 barrel cover. Z-RAM chose this one because it was available, but it basically comes down to the same thing: making the appearance a little more coherent.

The handle is then slid over here, and these screws are screwed into place. Here is the screw for the handle; it is screwed into place as well. There has to be some room for it here. That is basically done now.

As you can see, it is a pretty long setup with a long barrel. Z-RAM will also offer this setup in its shop; the offer should be linked below. However, the second barrel cover will not be included in the offer. If you want to use it, you can order it along with the setup, or you can simply order two of them.

Perhaps you want to screw the silencer on. Z-RAM is going to screw the scope on now. Unfortunately, it does not fit perfectly here. Unfortunately, Z-RAM does not have a scope in its shop, but if you order one, make sure it fits the Picatinny rail. There is also an adapter on which it fits without any problems. This has only been done provisionally: it is holding for now, but that is not ideal. Make sure you find a scope that fits properly.

What does it look like now? That is done. Z-RAM will fill the bottle now, and then the whole setup will be checked on the chronograph.

The bottle has now been refilled. Here is what the setup looks like. You can also use another grip here if you do not like this one; Z-RAM likes this one. Now let’s see what the chronograph has to say about it. The Z50 V2 projectiles are loaded here.

Now let’s see what results this achieves: 520 FPS. That was the last shot.

Umarex HDR50/TR50 shooting results: 520 FPS and about 77 J

The silencer has now been screwed on. Unfortunately, Z-RAM’s chronograph is not working at the moment, so it is not possible to test how the silencer affects the energy. However, it is possible to see whether it is louder or quieter. Z-RAM has also put a little board down for fun.

The result is devastating as well. As you can see, it is a clean cut, a clean shot. The one down here was about 30 to 40 J. Here, however, these 520 FPS, which correspond to about 77 J, have created a clean hole—a very destructive exit wound.

That is it for the shooting tests. As you have seen, this setup has produced extremely good results: 520 FPS, which is about 77 J. All this is with super-sharp projectiles that weigh 6 g. These are devastating results.

Umarex HDR50/TR50 package contents and ZDR50 V2 alternative

As already stated, you can buy this setup as a complete package in Z-RAM’s shop, but without the marker. If you order the complete package and want it exactly the same, the only extra thing you have to order is a second barrel cover. Of course, this is not mandatory for these results; it is only for the appearance. There is also the silencer, if you want it. Otherwise, of course, the standard extension of the tuning barrel is included.

The scope is also not included; Z-RAM does not have that in the shop. The same applies to the marker, which is not in the shop either. What is included is the tuning barrel, two sniper extensions and the standard extension, the ASA-to-chamber adapter, the regulator and bottle, and the buttstock. It is all included.

The block and the valve down here have been completely removed, although the valve here makes no difference now because everything flows directly into the chamber. That is just mentioned for completeness. The shots were taken with Z50 V2 projectiles.

As already stated, if you are looking for a short setup with really cool results, Z-RAM recommends its ZDR50 V2 valve with the matching case. You then already have 38 to 40 J in a short setup. You do not need this for a long setup, but you can also build it with the ZDR50 V2 valve. You then screw the ASA-to-chamber adapter on here and screw an empty capsule in down here so that it is easy to close and more stable. You can basically do the same thing with the ZDR50 V2 case.

But 520 FPS, 77 J, with sharp projectiles—you can find this in Z-RAM’s shop. The shop is linked below. If you have any questions, feel free to post them in the comments below. Z-RAM will try to answer everything as soon as possible. Otherwise, leave a thumbs-up and subscribe to the channel. See you next time, from Z-RAM.

Z-RAM Z-Extension Tuning chamber-extension for all Umarex T4E Typs & FSC/TCP

The standalone Z-Extension offer contains the chamber extension and its O-ring. It is useful when buying that component separately, not as a compulsory extra alongside a set already containing it. For FSC/TCP use, the product identifies a separate adapter requirement.
