Airsoft homemade DIY 3D printed HPA sniper rifle BiG-no HPA engine, no batteries
HTML-код
- Опубликовано: 31 янв 2023
- I have to mention that after testing on the field the second version I concluded that the 250psi that I used in chrono test is to much resulting in dropping range and accuracy. I recommend around 130psi instead.
----------------------------
Here's a build that proves you don't need any fancy HPA engine or batteries to make a HPA sniper rifle that performes the same as any expensive one and is extremely silent.
You can download the .stl files from here:

I’m working on making a semi auto Hpa airsoft gun and this video has helped a lot so thank you for making this
I'm glad it was useful for you.
Check out the second version also here:

Good job Bud amazing design
love it might buy and build for myself
Thnx.
V2 is coming soon...next month I hope

very nice design! very very good. PS: the "mini-tank" in the pistol grip is some kind of "air reservoir"? making it smaller could decrease output power?
Thanks. If you want less power you need to decrease the air pressure - less psi
Kudos! That's a great design, the mag is so versatile! Horizontal load, rotative selector, being able to carry various types of bb (grams, tracer) in the same mag.
I'm looking for diy modding a Well sniper and I love the simplicity and electric needless of your system!!
Some questions about the HPA valve:
-Guess the "reservoir" in the grip is for both limiting air volume expelled, and to act over the valve as some kind of "timer" (like IC controlled electric systems like P*, wolverine etc), therefore the two position valve, so acting in two times, being 1st. trigger pull--> reservoir loading, 2nd. trigger release-->reservoir propelling the BB, I'm I right?
-So, changing reservoir size-volume would affect to the energy and flight of the BB (being an optimal amount of air for best performance and accuracy)
Did you do some sort of calculation about that?
I'm intrigued about that since you stated that longer trigger pull had some effect over FPS readings
Thanks for answering and sorry for the long text!😅
Hi,
Your message is well received no matter how long it is. 😁
The air capsule inside the grip has a bigger capacity then needed, but that's not a big problem, only that I'm wasting air. I don't have a CNC mill to make the proper size that can be calculated multiplying by 3 the inner barrel air volume.
The valve doesn't work as you said. When trigger is RELEASED, air flows from the air tank in the air capsule( first "way"). When trigger is pulled, the air flow mentioned above ist cut off and opens the second "way" from the air capsule to the BB loader pushing the BB out the inner barrel.
The big advantage of this valve is that is very, very, soooooo very silent.
The disadvantage is that you have to have a quick and ferm trigger pull because if that is to soft or slow, the air from the capsule doesn't come out all at once but gradually and you'll have insufficient air pressure. It's all in your index finger ability. 😁
If you have more questions, feel free to ask.
As an extra info, I can tell you that I've upgraded my rifles with my own BiG TDC system, so not far in the future you will see the upgrades and shooting test videos.
I only say that my BiG TDC made my sniper rifles laser accurate.
Stay tuned.
@@BiG_1977 thanks so much for the detailed response and the info! I'll await that TDC video, sounds good! I'm assuming you are using that TDC BiG system in substitution of any market hopup chamber, or is working over it (as aftermarket top dead center regulators do, over the hop up lever)?
Cheers!
Looks like the ones on the market but is very different. 😁
You'll see.
Pretty ingenious with the push button valve setup here. I've been ooking to replicate the polestar Kythera (somewhat) with a no electronics setup. Quick question regarding the air cell used in the setup, I am assuming the size of the cell is proportional to the output power when the switch is toggled correct?
Another thing, how are you getting along with that regulator? I've seen them on ebay for cheap but am always a little concerned about using one of those cheapo regulators.
The "air cell" size only matters when you calculate the volume of air you need to expell in one shot (I didn't had the tools to make one the exact size but it should be 3 times the volume of inner barrel). Bigger cell doesn't mean more power. You have to do some math taking in consideration the mass of the projectile and the barrel length.
The regulator works, but for its price you don't get to really fine tune the output pressure. If you wonder if it holds, the answer is "yes". Keep in mind that you need also the 800psi regulator, otherwise it doesn't work and I don't recommend you to try that. It's not safe. First you need to go down from, let's say, 3500psi to 800psi with one regulator, and the from 800psi to 0-300psi with the second adjustable regulator.
@@BiG_1977 Most tanks nowadays come with a regulator to take it down to 800 anyway.
would it be possible to adapt this design to fire 4.5mm Steel bbs?
Of course, but you'll need a different inner barrel and I don't think that a hop-up chamber will be needed anymore. But then, we're not talking about Airsoft anymore. It will become a PCP gun with different regulations.
where did you source your springs from? im having a difficult time finding the magazine springs. this is an amazing design!

Thank you!
sir can you put list of materials pls?
I added the list in description. The prices may differ but I can say that I spent approximately 250€ for all the parts.
Salutare, ft frumos proiectul. Ma apuc si eu de modificat un mk1 zilele astea.
Eram curios de ce rezultate scoate pe hpa. Am vazut ca ai dat direct pe 300psi.
Ce valori ai la 300psi ? Cati j ? Ce bile?
Ai facut si teste in teren ? Ce rezultate ai ?
Ai facut r hop ? Cu guma folosesti ?
Mulțumesc, sper sa ne auzim
1. Ai in video toate răspunsurile la întrebările tale.
2. În curând voi face și test pe teren.

so very nice sir! do you have stl files for these?
I'll post a link today.
Done.
@@BiG_1977 I am a great fan of you since the mk1 video that you made it to a pcp.. the problem with that build was you can't control bb since mk1 has steel hopup.. how is the accuracy with this one sir?
also is it possible to reach 5-10 joules with this? or atleast 800 fps?
The fact that the KJW MK1 hop-up chamber is made of metal is no problem. The problem is in that setup the barrel moves forward and backward every time you pull the trigger. That's making the gun not so accurate.
hello or I can find ????
refill adapter(1/2" threads X 1/8" threads)
1/2" fitting (inner threads to outer threads)
1/2" to 1/8" reducer
I LOOK EVERYWHERE IMPOSSIBLE TO FIND
Hi,
What country are you from?
I'll look it up for you.
I used this combo:

Is there a way to convert SodaStream bottle to work?
Yes, but is risky. An air tank like the one in the video is not that expensive and is safer. But if you still want to use a SodaStream, you have to buy a regulator with matching threads - evidently - or you have to use an adapter of some sort and you have to ensure a good air seal, witch is going to be a little tricky because on the SodaStream bottle you don't have an O-ring slot.

Where can I purchase the parts
You have a link in description for 3D parts. For the rest, just Google search.
ruclips.net/video/WZ2VhWV6FpI/видео.htmlsi=-fjZ6j6O4BIkVm7X
Can i buy It?
Yes, you can, but not an already built one, because there are regulations regarding shipping per Post even if it's about airsoft replicas.
In the description you have a list with all materials you need and a download link for the 3D printed parts.
Cool but I'm not paying 10 bucks for it
Yes, it would be nice to get everything for free, but then we have to ask ourselves "Who's gonna work to produce everything we get for free?"
It's your choice, I'm not forcing anyone to buy.

Im just taking inspiration so that i can make my own. The mechanical solenoid valve is pretty smart, kinda shit how its implemented cuz of the trigger pull, i'd make it an AR-15 style trigger for sure, but pretty smart nonethless
Серьезно? То есть у него есть все для нормальной воздушки, но он делает тупой пистолет на со2 и показывает это мол "революция, я поставил на ЭТО прицел, смотрите все я гений" чел ты наверное не знаешь про канал 60БАР там мало того что автор показывает как из говна и палок сделать супер воздушки с разными клапанами, так он еще этим делиться со всеми, а ты что сделал? Соединил 3д шаблон с готовыми узлами для компрессора?) 😅😅😅 бред.
I understand that you have a problem with what I did, but can you post again your comment in English? I would very much want to know exactly what you mean to say. As you know, Google translate doesn't have very good results specially with languages like russian.
Thank you.
