Umarex HDR68, 16 Joule Version, Without Restrictor

Just a test to see if the 16 joule version will give the same power as the 7,5 joule version when both valves are open.

Updated numbers for your Rune- I finally broke the 50J mark with this bad boy. Using 7.65g. HP68 and HPA around 1000psi. I got between 53J and 47J. It drained a 13ci about as fast as a 12g CO2, which I found surprising.. I only shot the one, 5 rd. magazine, but was down to just under 1000psi at the end. Probably would have gotten the extra 2, for the 7 shot total, I normally get with 12g. I put various shapes, brands and weights from 2.9g to 11.0g through after that and completely shredded my target! CO2 to HPA... What a difference from the same rig, in the same 61⁰F room.

Hi again and thank you for sharing! So ,i am thinking to remove that restrictor.Is that worthy,really? I can't modify too much my HDR 68 as for Italian laws so i am thinking only to change the upgrade cartridge pincher pin .I would love to full upgrade but i al not so much in need to do so . Removing the block restrictor, neither as I think i will shorten the life of the gun. Mauve upgrading the valve but removing completely i think too much pressure will ruin the cartridge chamber with the time.Upgrading the valve makes sense to me with a little bigger hole , would cope well enough pressure. Thanks Again!

[@runerebel8441]

Thanks my friend🙏. Iam glad you like the video. Hmm 🤔. I guess you have the 7,5 joule version. If so it dont have that restrictor, only the valveblock. If this is correct and you only want to make a slight modification then just drill the hole in the valveblock a little larger. This will make it hold a little more CO2 and give it a slight rise in velocity. I have not tested this myself but it should work🤔. Good luck 👍

[@MirrorMan369]

Thank you again for your kindness and attention.The valve drilled ,in my modest opinion,is safer way to improve the speed than to remove completely the valve , less stress of air for the pistol and dispersion. Maybe I will buy the upgraded valve as I don't have even a drill😅.By the way I have a 16 joules version and will only change the pin which perforates the cartridge and see how it goes with normal valve.(HDR 50 or 68 seems the same) Then I am awaiting for the delivery , today ,of Quattrovolante Silencer extender which appears to reduce 20-22db of BANG ( which is not bad at all actually as far as it is well advertised ) I will see how much it will improve only with the pin and extension and then I can tell you.if you haven't done it already yourself. At the same time I would like to ask you ,do I only need a common screwdriver for the removal of that valve? I checked inside my HDR 68 and looks like the depth of the lines to insert the screwdriver aren't deep enough.Maybe a new version valve? It's sounds odd ,tough but before ruining the valve with the wrong tooll I want to make it sure nothing has changed in the costrution.. I wish you a decent day my friend I have problem of artrosis at my knees after a bar car crash which left myself disabled. Take care.

[@runerebel8441]

Hi my friend. Since you have the 16 joule version you have almost max power from right out the box. The only modification you might do to it is drill the small hole in the restrictor that sits in the CO2 tube. That small hole can easily be clogged with dirt. I recommed you drill it with a 1mm drillbit. That should prevent any clogging plus even give a little more power. Good luck and happy shooting 😃@@MirrorMan369

Which HDR 68 version do you recommend for getting the most power out of it? The 7.5 J or the 16 J versions?

Thanks my friend. It seems that the 16 joule version has an edge over the 7,5 joule version. But its not much.

Hei. Bruk den som den er. Hvis du skyter uten restrictor så kan heat-core O-ringen ryke. Uten restrictor får du maks 5 joule mer på første skudd, og kun 5 eller 6 skudd totalt. Viktigste du gjør er å bruke riklig med silikonolje ned i CO2 røret. Dette holder pakninger mye og velsmurte :)

@@runerebel8441 I took the restrictor out of my HDP50. Instead of the usual 18 shots, it only managed 7. In theory, that could mean an increase of up to 2.57x power. That would mean 28 Joules out of the 11J model. I still have to measure it on chronograph to see what I actually got. Sadly I don't have a radar chrono but a cheap airsoft chrono, that gets confused with the CO2 gasses, so I have to shoot from a distance and risk hitting the chrono. That's the only reason I haven't measured it yet... But clearly, there will be an increase in power, considering the drastically increased CO2 use.

I did get one reasonable reading of just over 25 Joules. I wish I had a more reliable chrono, so I could see consistency. If gas is being wasted, I could try drilling larger and larger holes into the restrictor and putting it back in, until I get 6 shots of somewhat even power...

The second flaw is the way the revolver cylinder rotates, if you let go of the trigger before firing, it would have rotated the cylinder already, it rotates before the shot not after, so if you only have 1 round in the drum you will shoot empty.

Due to the smaller *volume* of the 50's bore, the 68 allows for a faster pressure equalization between bolt strokes/sear timing, and the bore volume *'dump' vs AC pressure... which allows the spring to overcome the air pressure and seal the valve/engage the sear before dumping the CO2 cartridges entire contents on the first shot. ( * dump = the point at which the projectile leaves the muzzle, the remaining air escapes and, the internal barrel pressure becomes ambient.) I'm not sure if that description makes any sense, but it's what happens. lol The same effect occurs when you lengthen or shorten the valve pin. CO2/HPA flow efficiency would then be determined by the flow regulator/restricter hole size once the valve pin length/timing for that given velocity is determined? Am I way off base here, or did I just have a stroke? lol

Do not use an allen wrench to tighten Gen 3 HDR 68s... weakens the Gen 3 cylinders. I never have to use an allen wrench to tighten an HDR 68, only to loosen it after the shots. I only need to use an allen wrench to tighten my HDP or it won't puncture. If you have arthiritis and can't puncture it without an allen wrench, then you should sell your Gen 3 T4e's trade it for a Gen 2, or put ducttape and thread sealant to reduce the odds of failure. You also should drill a hole in the handle grip or else the polymer grip could explode.

Both versions give abouth the same energy when you remove all the restrictors from the CO2 tube and valve. The 16 joule version is easiyer to powertune. Just use a flathead screwdriver and remove the restrictor from the CO2 tube. The 7,5 joule version must be opened up to remove the valveblock. So a little more work on the 7,5 joule.

@@JayNetral Thanks my friend. You can have the CO2 canister inside it for as long as you want if you dont hitt the puncture knob. If you dont gas up the gun you are safe and it dont harm it in any way. The problem I had with the heat core O-ring is when I use heavy and tight fitting ammo. This makes some sort of back pressure inside the valve and the O-ring popps out. To prevent this happening just use ammo that can roll or slide out the barrel, or light weight ammo. With a restrictor you get ca 28 joule and 10 full power shots. With an open valve (no restrictor) you get ca 30+ joule and only 4 or 5 shots.
