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!
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?
@@V1P3RSlab the small tank is used for one shot. When the valves button is not pressed, the small tank is filled. When you push the button/trigger, the air from the small tank is released and the link between the big tank and the small one is closed. After releasing the trigger, the entire process repeats.
Do you think maybe a longer barrel would help with the loss in accuracy at higher pressures? My field has a 550 fps limit and taking full advantage of that seems very beneficial if it can be harnessed. Additionally, with this system how efficient is it (how many rounds does it last?). I love this idea and want to maybe try it out for myself.
@@craftingclasher3791 First of all I recommend choosing a high quality inner barrel. The length is your choice, but this length will directly influence the air volume and pressure that you would have to use for maximum accuracy and speed. This is the delicate balance that you'll have to figure out testing out with different air pressure values. Take a look at the shooting test video for the version 2 of this sniper rifle. Good luck and have fun! P.S. With a full 0.3 liter air tank (I go to max 3500 PSI for safety) and an HPA sniper rifle you don't have to worry that you will go out of air even for a whole day of playing time.
@@j7yuhy418 The design is made to host the Maple Leaf Crazy Jet for VSR10 inner barrel with Maple Leaf hop-up rubber. If you have another inner barrel and hop-up rubber with the same dimensions, it will fit. The problem is that I have 2 VSR10 inner barrels and 2 VSR10 hop-up rubbers from different manufacturers and the dimensions are not exactly the same. Both will fit but with the difference that one will be a tight fit and the second .... will be a little loose.
@@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?
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.
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.
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.

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.
