Thanks for testing out mods to HDR50. Yes these air guns are nice to have even if you do have real firearms. I would use them as first resort to scare off any would be intruders before resorting to using real firearms. At 15 FPE or better these should make quite an impression without killing the person you are shooting at.
You linked to two upgrade kits. One for the 7,5J and one for the 11J version. Why are there two upgrade kits? How are they different? I thought the 11J version doesn't need the fitted disk shaped part because it is already fitted when you buy it?
I pulled the valve plug, and drilled out my CO2 restrictor to about 1mm. Huge difference, but I definitely burn thru the gas quicker. Tuning barrel next which tends to make another big difference according to tests I've seen.
Hello. What I really don’t understand is the installation process. In your video is very easy. On other video is extremely long and a complicated (at least for me). Which is the simplest mod for the HDR 50? I just want some more power for my 7,5 joule model but I’m not able to install complicated mods. Thanks 🙏
Hello. I have the 11 joule version and I removed the valve from the block. Now I made a hole in the restrictor. I brought it to 1 mm from the original 0.2 mm and it has good power. I lowered it to 0.68mm and I think it maintains the power but more constant in 2 rounds. What do you advise me, put the 1mm one back or enlarge it to 1.5mm?
@@garlicboy5692 same hole mad dog drill 1.5mm. I drill 2mm. In my kit I get stainless teel..hard like hell. Afraid to brake a 1.5. Get around 18 hard punch..predator 4.8gram.
Hi! My name is Kevin I don't own one of HDR 50 and I've watched some of your videos and I'm disabled and would like to own one and get the most power out of it for home defense. However I'm told there are different versions and if I order the wrong one I won't be able to upgrade it . I live in the USA and would like to ask you what version should I purchase or are they all the same I see a 7.5j & 11j I don't know I just want to protect my family I'm almost 60. and out of all the videos I've seen you are the most knowledgeable can you help me ??
Either the 7.5 or 11 Joule can be modded for more power, if you get the 7.5 joule version it doesn't have the co2 restrictor disc in the handle, so when you remove the valve block you will need to put one in. All parts come in the powerkit50 from homedefence-24
That's really odd I have a 7.5 joule model and even without the blocker and valve removed it doesn't just pour out the barrel. I only get about 6 shots but it works fine
@@homeagent Yes Both more power and louder. Power is about 450-500fps depending on ammo or the really heavy stuff 275-350fps depending on weight. 6-12 shots usually around 8. Now with the hpa hooked up I have to put it back in or it will pour out the barrel unless I turn the pressure down. So if I'm running HPA anywhere from 800-1200 PSI I have to put the blocker back in the grip.
I used a gun cleaning pick to increase the hole size in my T4e and I use nothing but Deeez Bullets from eBay ,they are perfect and impact harder because they're made to leave the gun faster with a flat base instead of the hollow base for the ammo.
I have both versions, and never had a jam on either of them. I did have a problem when I changed the barrel, the barrel spring got wedged so the barrel couldn't move and it locked the drum, easily fixed and not a problem since.
Ost jams due to ammo if gun maintained properly. I make my own ammo amd check diameters and lengths of slugs and purchase the balls. If you get jams I'd look to the ammo if action working smoothly .
@@franklinesau3635 hi. What's the price of the barrels? I removed my valve and frilled the co2 restrictor to 1.5mm. Pretty loud now. Get up to 8 solid shots.

Once I charged it with co2, and it's shot already few times, I don't know how to open the bottom again to change the co2, could you make a vid? Mine seems to be stuck
By way of comparison, American police non lethal launchers start @ 17 joules. Of course, now you need to destroy something with your modified launcher 😃
Bro please can you help I'm so confused I'm in a wheelchair aswel so I need good defence I have hdr50 11 joules version I been told the power kit is useless for the 11 joules version and rather then buy a power kit I just need to make this hole and there's no need for the power kit can you please help
@@sully9836 It depends who you talk to, some say it's just snake oil and makes no difference, but I have seen slight gains after fitting the power kit. You will get more gains by fitting the tuning barrel and extension if you have already removed the block and drilled the disc.
@@Maddogairguns last question sorry I don't want to take up to much of your time can you make the 1.5mm hole in the disc and use power kit same time also what would u recommend would u recommend a power kit or making the 1.5mm hole or both I want max power at the same time I don't want to run out of co2 ridiculously quick getting very few shots
@@sully9836 The more mods you do, the more CO2 you are going to use. So it's up to you where you go with it. Mine is 11joule version, valve block removed, disc drilled to 1.5mm, shorter pin fitted, tuning barrel fitted, it now makes about 25joules (depending on ammo) but only get about 5-6 good shots with good power and then it tails off a bit.

Hi Mad Dog,
How much PSI do you reckon the block would sustain on that air pistol?
First is the lowest energy because the space is not up to peak pressure.
Hello. I have the 11 joule version and I removed the valve from the block. Now I made a hole in the restrictor. I brought it to 1 mm from the original 0.2 mm and it has good power. I lowered it to 0.68mm and I think it maintains the power but more constant in 2 rounds. What do you advise me, put the 1mm one back or enlarge it to 1.5mm?
Drill 2mm, for faster load up the cylinder between every shot, get good power to.

Will drilling at 2mm be more powerful?
Might be a bit, at the cost of a lot of CO2. 1.5mm seems to be the sweet spot for power and CO2 consumption.

do you have to drill out new valve or can use as is
i can not get on the homedefnce 24 link you put up i am in the uk would that make any diffrence ?
do you have the diameter of the insert?
Use torch tip cleaners to make the hole bigger in incremental sizes.
I used a gun cleaning pick to increase the hole size in my T4e and I use nothing but Deeez Bullets from eBay ,they are perfect and impact harder because they're made to leave the gun faster with a flat base instead of the hollow base for the ammo.

Just roll electrical tape around the drill bit shaft and the Jaws will grip it.
it will not be centered and it will canter when you start drilling. Talking from experience.
@@joelplease9039 So you're saying FUZZY WUZZY WAS A WOMAN!

Technically you can't as it is over powered for a pistol, but I think you can get an 11joule from some paintball suppliers.

If you have the 7.5 joule version, you won’t have that piece in your gun. If you fit the powerkit, the piece is included in the kit.
I'm confused on you crono readings. Are you at meters per second or feet per second?
Meters per second, with the energy in joules at the top.

Release the pressure, by pushing in the pin that pops out when you charge it. It should then come undone.
Does anyone know if I can make this gun with a 3D printer. I'm stuck between buying the HDR 50 and a 3D printer
