Missed opportunity to say *”hi, I’m out of darts, but you might still have a few”*

Just got my spring the other day, took me maybe 10 minutes to disassemble, upgrade, and reassemble thanks to this video. Word of warning, this makes it even more difficult to pull the slide back, if you don't have good grip strength you may want to avoid this mod, my gf can't even pull it back at all anymore(shouldn't be a problem for those of us who are just kids at heart and not body). But I must say, wow, the power increase is pretty incredible. Far better than I expected. I put some petroleum jelly on the o-ring to get a little better seal and the gun shoots so fast now that i couldn't possibly want anymore in fear i might break something or really hurt someone. The nerf balls fly across my house seemingly instantly(~50ft from one end to the other, going over 130fps, there is pretty much no time to react), could easily take out someones eye by accident, even from just a ricochet. Fucking sick, I love it.

Dude, that 3-D printer is working in the background!!!

I ordered a Kronos and a k25 from your website a couple months. To my surprise, this was a really easy and effective mod, even for an 11 year as myself. Now my Kronos averages a speed of 120-125 FPS. For kids under 14, I would recommend a K25 spring cause a k26 would be a little too hard to prime, and would therefore be impractical to use in a Nerf war. I highly recommend this mod from out of darts.

Thank you! I was not modifying a gun, but my son took his sister's gun apart to get a non nerf ball out that had jammed it up. So I was brought the pieces (which were amazingly all present) and asked to get it back together. This video was exactly what I needed. Thank you.

My parcel arrived yesterday morning with your pre-cut K26 and my Rayven parts, I'm looking forward to installing the spring, it seems like a pretty simple mod, so shouldn't take too long,. Thanks Luke, you're an absolute diamond.

Absolutely lovely tutorial and I've seen quite a few for the Kronos at this point. Exceptional lighting, clean presentation, and well spoken. Well done sir! Looking forward to seeing more.

I bought the Kronos spring from OOD and upgraded my broken Kronos. I watched this video and was able to mod my first blaster. I felt so accomplished! Thank you Luke for this video!

Top notch mod guide! Well done! You should do mod guides for all sorts of blasters, I think that would be really helpful. (Not just Rival)

Ordered the spring off of etsy after watching this video, thanks for the extremely quick shipping and thanks most of all for turning the kronos into a hand cannon lol. Priming is definitely more difficult, but that is to be expected from such a strong spring.

If you get a chance look up the physics behind the Tippmann A5 Flatline Barrel on paintballs. The Kronos works the same way. There is a notch on the top side of the barrel about an inch inside. It's easy to feel, just put your finger in the barrel and you can feel it. What this does is as the ball exits the chamber it creates an upwards spin on the ball. This is effective upto a certain range, and what it does is makes the ball fly straight up to a certain range. After that if the spin still exists and the momentum is still present (which is what happens with higher tension springs being in) it'll zing off to a random side based on which way the axis of that spin will rotate, left, right etc. This is based on the balance of each individual Nerf ball. Some will balance to rotate one way or another, but the same ball will also zing off in a random direction. So, if the balance of the ball is more towards one side one of the two 360 degree access, there is no way of controlling which way that ball will be facing when it reaches the notch to generate that backwards spin that will make it go straight. So, it is advantageous to have a higher speed, which will get the ball to go further and be accurate... but where with the normal spring the ball will just start curving down, with the higher tension of spring, the chance to arc will be reduced to an accurate degree. Well... that's the physics part of it anyways, how it actually reacts can vary.

I just bought 2 k25 springs the easier one to prime cannot wait to try them out - Love the content OutofDarts keep up the great work !

@Outof Darts I’m about to mod/paint one of these and this quick video has helped me plan out my build so much! I paused and screenshot a ton of images from this to use as reference. I couldn’t be more appreciative. Thanks!

I dropped you and your Etsy store a mention in the "show more" section in my review of the Kronos, for the K26 upgrade spring you sell. It's a great blaster and I look forward to modding mine at some point when I get the K26 for it. You do a great service in cutting the spring to the right length and removing all the sharp ends for the Kronos, saving us who don't have the special tools to do it for ourselves. Thanks Luke for the great videos, store and service you offer, you have a great selection, I'm spoiled for choice, I may have to get some Hammershot cylinders from you as well!

I ordered your spring before I even had my Kronos 😂…the spring arrives on Tuesday and I can’t wait to drop it in

just received my k26 in the mail. thank you so much. i cant wait to install it in my blasters

When I got my Kronos I thought is was you know just gonna shoot a few feet like yknow standard elite range. Oh how wrong I was. Why even mod it is fires as far as the regular rival blasters

Welp, I modded it, it was impossible to prime, opened it up to try to put the original spring back in, and lost the trigger spring..

Straight to the point, concise, informative and simple. Love this video man. You just earned yourself a subscriber :)

So hard to pull back, shoots as hard and a paint ball gun just foam balls. Thank you so much man.

Yes!! Definitely like seeing mod-guides from you. Your setup is just really nice and I love the shout outs to Captain X and Nerf Curator

I ordered two of your easy prime springs for the Kronos. I'm planning to disassemble and upgrade both of my Kronos', as well as paint them. I couldn't think of a better way to do a minor upgrade than replacing the springs they've had since I bought them both. One definitely shoots harder than the other, this should equalize them. Then, the paint should make them truly amazing.

wouldn't let me review the 3.7 k25 spring on the etsy shop so i will here. fast shipping, easy install, works great. Girlfriend won't be too happy to get hit by this!

Thank you for making a clear and informative walk through for this mod. Can't wait to crack open my two! :)

JUST ORDERED ONE!! THANK YOU!!!!

Why the hell am I watching this?

1:50 y'know, that's the first time I've seen a nerf video mention eye protection, which is funny because just today I got whacked in the eye by a flying piece of plastic I had just nipped off a sledgefire. Gotta love the irony.

Thank you! Just got my upgraded spring today and swapped it out, it’s a lot more powerful now!

I bought a spring from u and completed my first mod using this video. Thanks!

UGGGGHHHH I've been waiting for the Kronos for so longgggg

I’d really like to see your take on MrHeathpants’ return spring mod to the Kronos. If you could make that modification readily available, that would be terrific! The return spring mod is something that Kronos needs!

Hey Out Of Darts i just bought the K26 and K25 springs from your store to see which one I could handle but anyways thank you for the awesome tutorial

Mr. Out of darts, it's funny you just posted this video I just got this blaster and ordered the K26 from you today.

Amazing mod guide. Good lighting and easy to see What you are doing to the blaster

bought a spring off your shop because of this video. about to try the mod!

Dude great video, just modded mine today w a spring purchased at ace, that sucker crumples soda cans now. Very easy to do thanks to your instruction!

I've bought your k26 mod kit and just installed it on my Kronos, amazing video and Jesus Christ it has turned the Kronos into the most powerful Nerf gun I've ever had, incredible kit and I'm very grateful thank you.

I just finished the first of the Kronos with the easy prime springs (K25?) I ordered from you and just ...WoW! Usually just my Prometheus makes me laugh when I fire it. First time I ever modded any blaster and I'm giggling my ass off at the power and accuracy of this Kronos! It's a damn zamby killa! Gotta go upgrade the other Kronos and then get that K26 up in my Hades. Thanks so much for this great mod guide!

I just ordered the K25, T handle, and ghost door. I’m excited.

Well congratulations for your 100th video just noticied after watching for the third time... Wish you many more subs ...Happy to be here from the 18th video

Definitely found my first nerf mod

an important note: The piece you refer to as an optional safety is not part of the safety switch on the side. Rather, it's the lock that prevents pulling the trigger while the blaster is half-primed. I recommend leaving this in so you don't accidentally pull the trigger and have the breech slam close on your fingers while loading.

The old upside down plunger tube 🤪 Thanks I was stumped.

Congrats on 100 videos!

Thank you for this video, I'll be buying the part soon and I'll definitely buy from your shop!!

Interesting. I used a section of k25 the same length as the original spring and get an average of 140 fps now. It was incredibly annoying to precompress but once it went back together it functioned flawlessly.

Didn’t realize how niche this was

Thank you for this! Just ordered 2 of these from your store!

Do you have 3d printed parts for the rival XVIII-500.

While she's wide open trim that trigger spring post a 1/8th inch and polish/shape the release ramp it really crisps up the trigger pull

Im in Switzerland and kind of want to buy springs from your website but I dont know how much shipping will be If anyone could tell me that would be awesome

definitely would love to see the Hera & Mosfet tutorials keep up the good work brother! ;)

your k25 works like a dream keep up the good work

Fantastic composition. Very artfully done.

Ahhh I love your quality my man. I hope to have my set up like this asap

I upgraded one with a new spring and it has insane power i used a mower spring from the hardware store and it worked amazing

My dad bought my brother an already modded version of the Kronos and my brother actually added on the pullback primer for the gun which makes more powerful even more than yours.

I used this video to fix a jam and i love it 😍

Thanks for this simple and easy to understand tutorial. Mine ball pusher sometimes jams and I can't wait to crack mine open and see if I can fix it now

I already ordered a cut spring from you, and yeah, it now stings a little when you get hit. Thank you for giving me the main internal part to transform it into the Rival Desna. Now it just needs cosmetic work. I also re-inserted the plunger rod upside-down initially, so yeah...

Just got my K26 in today, worked got a nice performance buff...but was waaaaay too hard for me to prime more than halfway 😅

now I can cosplay with my deadpool guns rendering them incapable of firing.

when modding mine i like to catch the plunger in the catch mech to put it back in... probobly too hard to do with this spring lol

Great video, thx man.

With the K26 in there it's a monster to prime, most of the balls went sailing over the 6' high fence in my 50' long garden. the hop-up makes them sail right over the fence with level shots. I'll have to print a T-Priming handle or another kind of priming grip as it just slips in my hand when priming sometimes because of the lack of grippy surfaces on the Kronos.

I guess you could say you *Krono* 'ed the *Kronos*

Thank you for this video! i sub and picked the bell. keep up the good videos!

just ordered one too ...cant wait to mod it !!! thx

Hey Out of Darts, can I possibly commision a dual Kronos or Artemax for my nerf war loadout?

Help! My kronos's tiny spring came right out when I shot it! I am trying to figure out to fix it... can you help me?

Wait only 70fps for the stock spring? It’s supposed to be 90fps

I'm sure that higher tension springs can also wear the mechanisms of the gun faster. I think if you want faster shots that are accurate, you're going to need a heavier projectile.

Your screwdriver is a XShot dart in disguise.

Does anyone else hear the 3D printer in the backround?

O2D I got my new spring and holy smokes. Scary! Any chance that spring is going to wear out the OEM parts?

is there a way to make the safety easier to release with the thumb of your shooting hand? I have to use my other hand because it is so damn hard to push up!

i thaught you would do this. LOVE UR CHANNNEL!!

Out of darts? You mean OUT OF BALLS!!!

Muchas gracias por tu video, desde nuevo no pudo utilizarla y como fue regalo no podía aplicar la garantía, pero gracias ti ya la reparé, muchas gracias por todo!!

Hey Out of Darts, You said hirmini is coming out this week. You scared me so much

I ordered springs from you OutofDarts thank you for this mod video. It is very easy to follow. Can you please get your hands on a Starwars Captain Cassian deluxe blaster and do a MOSFET mod video in the future :D Thank for your videos and passion for Nerf..!

I have a two piece slide in my gun and I can’t figure out how to put it back in.

Great vid, I'll be hitting you up for those custom flat end springs when they are available!

I have two, I’m thinking of nodding them and duel wielding them by drilling out a hole in the back “rails” and tying the priming bar to a vest

Awesome vid! However when I went to order two, the cost of shipping was more than the springs. Any way shipping can be discounted? Im in Australia. Thanks

Lol is that a 3-D Printer in the background?

are there custom bullets you can buy to push the fps even higher?

Very crisp mod guide! I hadnt even considered curving the spring in that manner before cutting before. Seen some people being able to double load the Kronos for a shotgun 2 ball effect by fidgeting at the back of the slide possibility of making it more intuitive for a "Double whammy"? Would you consider doing an exploded view of all the internals? That orange circle infront of the trigger how essential is it for the internals, removable?

Wow very video return spring, thank you for sharing

Finally a mod guide!!!

Thanks, I followed your tutorial and it Worked very well, I'm in Mexico so I ordered the spring from amazon. I want to mod my takedown to, do you know if the spring measure is the same as the Kronos? Kind Regards.

I really like the look of this blaster. Could you fit the hirmini's internals into this guy? Dremel a hole in the back so it can take the mags and boom! Flywheel awesomeness!

Im 15. This nerf gun is accurate for nerf. Very inpressed

I would buy spring, but shipping rates to UK cost three times more than the spring

Is Air Restrictor removal not a worthwhile mod on the Kronos? Could an airsoft- style hop- up be used to get more distance?

At 5:38, you showed the cocking mechanism to stop it for half/full primed. How does it disengage since i dont see it connected/related to other parts of the trigger. Am having trouble wth my unit and found out that the cocking part stops the gun from firing

This was really helpful!

Great guide thanks

someone need to make a nerf rival ball steel breach

Thanks! It was super easy!
