Much better tutorial than others I've seen. I look forward to watching this again as soon as mine arrives. Thank you!

[@ModernIntel]

Glad it was helpful!

[@DarkPassenger07]

This is the best breakdown video for the hdx anywhere. Awesome job. I successfully upgraded mine last night thanks to you my friend! Well done.

[@ModernIntel]

Glad it helped

[@NeoAndersonATS]

I watched your video about 8 times before I got enough nerve to try to modify my HDX68. I increased my HDX from about 135 FPS to well over 340 FPS buy simply Drilling out the restrictor, the black plastic piece inside the valve. I want to say I drilled it to 3/8 from what it was. You have to be EXTREMELY careful when doing this. When I first put the gun back together it leaked like a bitch. I dunno why I was super careful following the instructions. I took it mostly apart again and when I reassembled it this time it worked perfectly. I used ONE full CO2 And one empty just to check. Gun worked flawlessly ever since and I''ve taken my HDX apart a couple more times. I thank you for this awesome video. Very detailed and accurate.

[@FLAlesslethal]

Looks like you've done this many times and can now do it with your eyes closed! The knowledge you just shared is priceless... Thanks! 🤟😎👍💥

[@ModernIntel]

Glad to help

[@RagnarL757]

Hey man just wanted to say thanks for the video, i just put on my 88 gram adapter from MCS and I used your video to help take it apart, i also took out the restrictor and man you weren't lieing that thing is powerful. Anyway thanks again your video really helped me. I also got a HPA adapter and can now pit a 13ci on it, fun times man.

[@ModernIntel]

That is awesome!

No problem 👍

[@mrgreenbudz37]

Excellent tutorial. So what would it take to turn this beast in to the 40 joule version and add the 88 grm Co2 cart?

[@kiddkoolarrow7904]

I just purchased a 40J from Defense Innovation and it will ship in February 2024. There is also the one in gray and black color. And then there is Modern Combat Sports.

[@mrgreenbudz37]

Well let us know when and if you actually get it. I talked with UMAREX USA months ago and they said they will never ship the 40-joule version to the USA. I would say contact them and ask@@kiddkoolarrow7904

[@Joreel]

​@@kiddkoolarrow7904Sadly it was pushed back to July 2024 and we expect it to be pushed back again for a sixth time since they announced the 40 Joule version. I simply bought my 40J HDX from less lethal defense last January and had it on my doorstep 10 days later. There's a company in New York that sells a 50J HDX that's been around for 25 years.

[@fgm1197]

Thank you for uploading this. I was looking for a good ENGLISH disassembly guide for so long. Is this TechT grease suitable for moving parts as well? Like the bolt-carrier group and trigger of the HK416?

[@ModernIntel]

You can use TechT grease for moving parts...but use it sparingly

[@leewalker1177]

Oh my word....theres no way I'd attempt this strip down.

[@ModernIntel]

Its fairly straightforward....

[@kamalboothe3317]

@@leewalker1177 I've done every mod on these t4e products from the hds the hdr 68 and was successful with them all except when it came to this one got it all stripped down got the valve block out and then I heated the bolt to get the valve pin out and it wouldn't come out with out a fight finally got it out but I stripped it to the point where the new steel pin wouldn't fit so I swapped it with the hdp bolt put the pin in that bolt and got it all reassembled and loaded it up and it wouldn't fire. Really sucks cause I was waiting for this for months and now I got this product that doesn't work just sitting there

[@user-mm9fr7yq5h]

Hi, would you suggest fitting a powerkit 68 to the hdx 68 paintball shotgun to make it more powerful? If so which one would i need and where to buy it from please? I hope you can help! Regards.

[@jhon9094]

i rebuild it and i don’t hear the click when pulling the trigger

[@jhon9094]

4:50 im stuck here, what type of screw driver do you need for this, each one is too thick

[@ModernIntel]

we use a small rubber handled pozidrive or phillips screwdriver

[@RevoLution83]

Bonjour jai un hdx.68 16 joules en France donc si je comprend bien le 7.5 joules et plus cohérent pour plus de puissance si ont enlève le restricteur. Pour un 16 joules si j'augmente le trou ou supprime la petite pièce en laiton qui régule le co2 ,aurais-je plus de puissance ? Merci d'avance.

[@ModernIntel]

Not sure what the restrictions are in France, but the 7.5 with the restrictor removed will give you more than 16J of power

[@desertdog01]

Cheers!!! Most folks will have the most insane Paper Wieght Boss!!!

[@ModernIntel]

its not that complicated...but it does make a nice ornament

[@desertdog01]

Do you show it shooting &sir?? and croney???

[@iomagicofly]

Hello there, thanks for your videos. What you think about the tiny little brass restrictor at the end of the brass little tube (after the o ring)? Someone says it’s better to maintain, other to flip….or remove…

[@ModernIntel]

Definitely keep it where it is, otherwise you get a totally inconsistent shots.

[@tjjbros]

What exactly does the little seal in the valve look like. Mine looks clear and fine but still leaks air and im wondering if there is supposed to be another black o ring or something?

[@ModernIntel]

There is only that one. If the clear seal is the issue then air will just rush down the barrel

[@kurt9994]

Thank you for this in-depth modification. I will admit if I ever get one of these I don't think I will try that. I am curious though if I was to purchase a new one of these and simply wanted to remove the handguard and then put it back on can that be done easily or do you need to disassemble other parts of the gun. Thanking you in advance.

[@ModernIntel]

Pump Handle comes off easily. the top of the handguard is integrated with the top rail

[@kurt9994]

@@ModernIntel Thanks so much for responding and I appreciate the answer.

[@karlmurray4479]

Can anyone help? The racking slide on my hdx 68 is stuck in the open position and won’t budge , nothing in loading tube/ chamber or any where else??

[@ModernIntel]

strip it down...best guess would be the spring has come out and has jammed it.

[@karlmurray4479]

@@ModernIntel 👍

[@blargus6535]

hey can i run this setup straight up without a restrictor? Just got my HDX last night and Ive completed the takedown but am unsure whether to drill out the stock restrictor or go third party drop-in performance restrictor, great video by the way

[@ModernIntel]

depends on where you are located

[@jaywise1956]

When I removed the pump lever a small spring hit the ground. I have no idea where it came from. Any advice?

[@bernardrizzo8305]

TRY LOOKING FOR THE ONE SCREW THAT THOSE PRICKS AT UMAREX USE LOCKTIGHT ON!!!!! I just had to drill out the blasted screw from the casing. It is the one on top right next to the rail mount screw and above the trigger assembly. Nothing i tried would get that loose. Since it was aluminium there was no way to heat it. To be frank, they didn't use any on any of the other screws so I didn't suspect that in the least. it is not like any locktight I have ever seen. It was silver and caked in the threads. Those weren't stripped threads... it was a substance that filled in between the threads. I have to see if i can find a similar screw as I was careful enough not to go all the way through. Even my T4E side by side didn't give me this much trouble and that one is jacked because of a seal leak at the pressure chamber that I simply cannot fix. My last attempt was using epoxy and it isn't coming apart anytime soon. Thankfully, I can use an adapter with a valve that can accommodate either a 16gram screw in or an 88 gram screw in. I just want to change out the pin in this HDX to get this SOB from a pea shooter to the 40 joules promised by MCS who also promised the factory upgraded one would be out in February and now is pushed back to July. Fuuuuuck.... this disassembly is a tough one. MCS offered me the anemic US version with an upgraded pin for me to install. I knew that this one would be harder but I didn't think that much harder. I'm starting to get a little put out with Umarex. My luger works for shit. My 1911 works for shit too. The Grease gun is just opk. The german MP, schmiesser, will simply refuse to feed at times. The thompson I am not touching cause I am sure that one will go to shit too. The side by side is fun and hits HARD but is unreliable. I am coming to the conclusion that Umarex makes CRAP.

[@ModernIntel]

Doesn't sound like a great experience!!! but ours couldn't be any more different, we've had very little problems with any of the T4E stuff and would go as far as to say its some of the most reliable paintball product out there.

[@Joreel]

You could have just bought the 40J version from less lethal defense directly. There is also a company in New York that makes a 50J version as well instead of trying to do it yourself and giving yourself a massive headache.

Needed this video!! Liked and subscribed, Thank you!!

Thanks for the sub!

[@FLAlesslethal]

Amazing Vid Content My Friend!

[@ModernIntel]

thanks

[@Prudyk1026]

Does that small brass “throttle” that sits at/in the brass airway tube restrict any potential power increase?

[@ModernIntel]

Paul, if you remove it you just get a wildly inconsistent HDX, it becomes a Co2 hungry paperweight.

[@Prudyk1026]

@@ModernIntel ok fair enough, so if i purchase the home defense valve pin but leave the “throttle” installed i would be able to achieve the 30j-40j being advertised?

[@desertdog01]

Wow , you are good!!? I wonder what a 40 joule has that is different. It must be a feature that much more advanced to get up to 450 fps. Cheers sir.

[@ModernIntel]

different valve we would guess, with a less restricted delivery of co2 - the 40J runs on a 88g disposable cylinder.

[@ruiz10100]

Hello, where can I buy the valve seals? T4E HDX 68

[@desertdog01]

It would be nice to open a factory 40 joule ,To see what are the diffences???

[@ModernIntel]

40J runs of 88g and the valve and firing bolt will be the only real difference

[@johnhogan6618]

Hi how powerful can make it

[@Walem_B]

Hello my friend do you think the 40joules is enough for home defense??? Thank you

If you're legally allowed to have it at 40 joules then yes....40 joules will break bones

@@ModernIntel ok thanks !

[@garethmccaig8674]

Does the 11 joule version have a restrictor similar to the 7.5?

[@ModernIntel]

Hi Gareth, we havent checked it; but would guess it does with a slightly different aperture.

Sounds like a bad seal. Did you check your seals to make sure they're secure and not damaged?

Any Uk owners with a more than 16 joules airgun are committing a section 5 firearms offence that carries a minimum prison sentence of 5 years.

Narc

Thats only kinda true If you have this gun AND rubber / solid balls that IS a section 5 If you have this gun and also have paintballs that is PERFECTLY LEGAL

not if its over 16 Joules
