I have made this video by request. I tested drilling the restrictor. First with a 1mm hole and then with a 1,5mm hole. Didnt seem to give any more velocity...
awesome test buddy , no matter what configuration these things are a blast to plink with !!! i havent done this test on hdr.59 yet on how much i can drill before it acts up like it didnt have a restrictor !... that would be very interesting also . ... good show as always my brother !
I think the reason why you don't see a significant difference in fps is that there is enough time between each shot to fill the plenum. You won't see any change in fps because every shot only empties the plenum/air chamber. What you could try is how both restrictors behave during rapid fire. Maybe even a test without the restrictor in it. A bigger hole will fill the plenum/airchamber faster which is always better for rapid fire. You could try shooting 5 rounds as fast as you can with the small restrictor and a fresh CO2 and do the same test with a larger restrictor hole (ore no restrictor at all) All you need to measure is the fps of the last shot of both tests. I think / hope the last shot with the bigger restrictor will be faster then the last shot with the stock restrictor hole. 😉
Yes that might be true. Cant test this because of my painful and stiff fingers. I strugge to pul the trigger as it is now, not to talk about trying to shot fast. But I think you are right. The power without the restrictor is just 5 joule more, and on the first shot only. I have several videos testing it without the restrictor. 😉
If you can find a welding supply shop. For tig welding there are fine hole cleaning "probes / Reamers" available They come in sets. On RU-vid I have heard 1.5 mm hole is good.
Jealous of the crest. I quote your 1mm hole all the time and without actual experience trust your judgement and refer viewers to the king Rune himself.
Hello Rune, Im getting my HDR this week, you mentioned in another video that the restrictor could be easily removed with a screwdriver? Is the slit across the disk where I place the driver? Is it the usual lefty-loosy/righty-tighty? (Do I unscrew the restrictor with a counter-clockwise motion?) Or do I have to drill as you showed in this video?
Hello my friend. Yes that is correct. One the 16 joule version it has a restrictor in the CO2 tube. Just remove with a flat head screwdriver like you say. Screw left (or counter clockwice) to take it out. I have not filmed drilling it. Its made of aluminium and very esy to drill a larger hole in it😃
@@runerebel8441 Thankyou!! I will try to watch several videos from lesslethalfordummies to get a good image of how I remove the valveblock too. It looked quite straight forward, but when finemotorics isnt on the same team, preparations must me made😁😁😁😁
@@runerebel8441 I can remove the restrictor alltogether and not screw it back in with a bigger hole? Or do the mechanism need somekind of stopper there?
@@Rolf_factchecker-Reborn You can romove it for max power, but you only get ca 6 or 7 shots from the CO2 canister. Only the HDR50 needs some sort of restrictor. The HDR68 can be used without one.
it sounds like there is a restrictor before the air gets to that place you drilled. take caution finding the real restrictor... and if you did not use a larger bit to bevel the edges around the hole you drilled , beveling allows more air to flow through a smaller hole. course i am never telling you what to do . i did not mod my hdr 50, i just tossed the 22joules valve in without further adjustment.
That blockage is interesting as it didn't seem soluble...? Perhaps a piece of plastic? Doesn't seem likeky to be build up from UMAREX canisters as their product is clean. 😎✌👍❤🖖 Love Brother
Yes. Its very strange, but I have seen this happend before. That why I drilled the other restrictor with a 1mm drillbit. It was black collored hard gunk clogging the holes... Maybe from the paint the factory used inside the CO2 tube. Not sure... 🤔 . Cheers brother 😃
Hello, i search a origin restrictor co2 for hdp 50 because i have perced my restrictor at 1 mm. For the garanty uma rex , i could install the original restrictor. Thanks
Hi. Not sure where you can find a orginal restrictor. You can buy restrictors from www.homedefence-24.com but they dont have the threads. They are just pushed in place. Or you can make one from the tip of a used CO2 canister.
Hello rune, I wandering how do you make a restrictor with an empty 12g capsule. I resently bought a HDR 68 without valve block but only do 5 to 7 shots. I feel it waste a lot of co2 and also think it shouldn't be good for the valve have no moderation. Thanks for your videos.
Thanks my friend. Iam glad you like my videos. Take a used 12 gram CO2 canister and xut the tip off. Cut it so it has a diameter of ca 12mm and then you file it down until it fits inside the bottom of the CO2 tube. Optimum size is ca 11,2mm. If the hole in the CO2 canister is larger than 1,5mm then use a punsh or nail and hammer the hole more shut. For strenght ad a drop of glue/epoxy. Make a new hole with a 1mm drill bit. Then just drop it in the CO2 tube and you are readdy for use. It can get stuck in the tube so if you want to remove it later just use a lond round file and fish it out. Good luck 😃
Hi. If it blows out the barrel then I guess the heat-core O-ring is broken. Lots of work to fix this but its possible. Just be careful when open it up. Watch videos of how its done before you try to fix it. Good luck
@@RobinVanTrigt Hmmm. Good question. I dont think I have one that shows how to work on it. But check out Less Lethal For Dummies channel. He shows you how to work on it. He is quite the expert on paintball markers 😃👍
The only problem I can guess might happend is that the heat-core O-ring might pop out or break earlier because of a higher CO2 flow. But I have shot thousands of shots and never had a problem because of this. That O-ring can also pop out if you use a tight ball/slug that can create backpressure. If you lube it with siliconeoil/spray every time before use you shouldnt have any problems.
If you remove the restrictor you will get ca 5 joule more on the first shot. But the rest of the shots will drop in velocity fast. You will only get ca 7 shots maximum if you dont use the restrictor. Plus the velocity will drop like a stone.
Excuse me dear friend, I speak almost no English to clarify my doubt, the restrictor has to be drilled, can't it just be removed? and the other friend in how much power would remain in J cordial greetings
You can use it without the restrictor, but power will be almost the same. So depending on ammo and teperature the energy will be 23-27 joule. On a warm day maybe 30 joule
Hi my friend. The power is about the same, but it uses more CO2 with a larger hole. I think 1mm is just fine on this model unless you want max power and remove the restrictor.
The modify pin is for when you dont want to use the restrictor. Its best for the HDR50. The HDR68 can be used with an open valve so its not needed in that model.@@ltlbrazil
Best way is to buy the Ammo6 mould from www.homedefence-24.com He sends all over the world 😃. The restrictor is very easy to remove. Just screw it out with a long flathead screwdriver 🙂
Mange takk. Hyggelig at du liker videoene mine. Ja det er bare å fjerne valveblock. Se min video hvordan jeg gjør det ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-L9_I4o5-xvI.html
hello friend, as I told you about the comments of another video, I drilled the restrictor at 1.5 mm that a machining friend made me so as not to damage the original, after testing at 10 meters I crossed a board that in the original configuration I could not do it with the same projectiles and at the same distance, moreover I noticed a greater recoil of the weapon with the modification. Originally I could shoot 10 full power BBs and 2 BBs with reduced power, since the modification I shoot 8 to 10 full power BBs and then nothing depending on the outside temperature. I use warheads machined at 17.29 mm on a 7.3 gram aluminum digital machine.
Liker videoene dine :) har kjøpt HDR68 og Grimsburg HP68. Hvordan ville du modifisert den enklest og billigst mulig? Tenker å bruke 12g co2 og ha nok kraft til 2 magasin.
Mange takk. Bor et 1 mm hull i restrictoren som sitter i CO2 røret. Den kan du skru ut med en flat skrutrekker. Det vil gi deg ca 2 magasiner på en 12 gram CO2. Kraften vil da ligge på mellom 25 til 30 joule. Gratulerer med fin revolver. Lykke til :)
Hola amigo, no hablo ingles, pero entiendo lo que escriben. Si agujereo el restrictor a 1 mm de mi HDR 50 habra alguna diferencia ? Tienes algun video con esa prueba ?
Hello amigo. Yes you will get a little more power if you drill it to 1mm. But dont drill larger than 1,5mm. Otherwice the gun will start farting and dump CO2 . I dont think I have a video testing this in a stock HDR50 in 11 joule. My 11 joule HDR50 is modded with long barrel etc and gives ca 30 joule now. I think with a factory/orginal 11 joule and a drilled restrictor you will get 20-22 joule depending on ammo and temperature 🤔
Hi rune I hav 11j hdr50 would u advise taking the valve block out and drill 1mm restrictor or leave valve block in an jus drilling 1mm in restrictor will there b any difference
Hi my friend. I recommend you remove the valve-block. The power will rise with 2-4 joule (maybe even more) just from removing it. Drilling the restrictor is for me a must because the small hole in it is easily clogged with dirt. After I drilled my restrictors I have never had any problems. Drill with a 1mm drillbit. No need to go larger.
Hello my friend. Yes you can drill it with a 1 mm drillbit. That should work fine. But dont go larger than 1,5mm. If you do the gun might start farting or dumping CO2.@@RevoLution83
