I made Dart Zone PRO MK-4 even BETTER!

This DZP MK-4 mod guide was paid for by Dart Zone Blasters, but they did not view the content before hand and did not control what I did or say in this video beyond 1) Mod Blaster, 2) Check the Velocity on the Chronograph and 3) Check the accuracy against my indoor range.
People wrote off the DZP MK4 pretty much immediately. $180, 200 FPS out of the box, why even bother? Well that's because Dart Zone massive overbuilt the blaster to give you the option to tune it to a much higher velocities. Not only do I mod this blaster beast to hit far harder than it's stock config, but I also fix some of the nagging issues (and find some cool tech with it) to show exactly what this blaster is capable of, and why basically everybody is wrong not giving this blaster a chance.

It's so cool that Dart Zone loved your review so much that they wanted to see what you could do to maximize performance. I doubt they'll make a stock blaster that'll hit that hard, but it gives them insight on what modders will do and what their customer base wants.

[@legomeaker101potato]

they said in the podcast that legally they CAN'T let it hit harder because over 200fps+ it becomes an airsoft gun (and that has a lot of different paperwork and can't be sold to under 18 year olds)

[@FflawedMetalhead]

Respect to dart zone. Can only wonder if a Mk 4.1 will be in the works.

[@The_King_from_Clash_Royale]

Exactly! Imagine if it's, like, a huge sniper rifle-looking blaster, probably the one that looks like Barrett 50 cal, that hits 120 FPS with low power spring and up to 300-350 FPS with high power spring? Maybe it can take full-length darts and half-darts, and can shoot mega darts, rival rounds, and ultra rounds from the muzzle like Nexus Pro? I would kill for that.

[@firetroop2775]

They can't officially go above two hundred But they're sneaking Through. somehow I am excited for the 4.1

I remember back when 300+ FPS was only achievable with something like Drac's pressure sniper, which could fire a dart like once per 15 seconds. Now we have this absolute lunacy, which can do a similar powered shot like 2 times a second! Ridiculous! Buuuut extremely cool.

[@Kuli24000]

Goodness me what a monster of a thing! 350 is beyond anything I've used. I shot myself with 250 point blank and I can't imagine more.

[@Thesnakerox]

So people were pointing out the similarities between the internals of the DZP Mk 4 and those of the Worker Swift...and now I'm inclined to believe that may have been intentional. Dart Zone might have made that design decision because they wanted it to work with components that already exist on the aftermarket!

[@m00k61]

So cool DZ did that. I love how they're sending out fixes for the Deuce Pro now too. So much so I bought a second one today lol.

[@albertosara416]

Walcom getting recognition from Dart Zone! Way to go man, that's actually amazing

[@MrLilredmachine]

Most powerful springer on the channel so far is the mega dart sniper thing that was on here. 220fps with a mega accustrike dart (2.6g) is 4.34 lb/ft 355 with a short dart (1g) is 4.13 lb/ft So it narrowley beats the MK4 out. Impressive numbers nonetheless, really brings home what you said in the original vid about the plunger volume being the same as the Swift, as the Swift with the 1.8 spring was good for 360fps as well, mine dod it with the standard metal plunger though. Slap an 18kg spring in the M20 you got kicking around there somewhere and you'll be up around 370 though, without having to break out the dremel. 😂

[@shatteredskies191]

I find that mega accustrike darts (at least the aftermarket ones) weigh about 3.3 grams

[@MrLilredmachine]

@@shatteredskies191 in which case the gap is considerably bigger between the two, and the Ranger (I think it's called) will be possibly over 400fps on a single short dart, assuming the re-barreling doesn't cause power loss.

[@Laval2400]

Dear lord those chronograph numbers are um impressive

[@MrLilredmachine]

Exactly the same as the Swift on the 1.8 spring with 550 barrel, so he was correct that it's got the same air volume! 😂

Dart Zone: Write that down! Write that down!

[@Telefrog]

It's very cool that Prime Time told you to go for it on modding.

[@supahvaporeon]

Generally, springer tuning is just making sure you arent completely solid in the back with the spring, and slowly chopping an inch or so of material until you stop getting performance gains/start loosing fps. The scar makes up a bit for your FPS loss on tuning because of the small barrel length increase, despite friction from the rifling.

[@whatstdiggn]

Dart Zone is the best company ever. If you'd have asked me pre nexus pro I'd have said we'd never be able to buy short darts at a retail store. If you'd have asked me three days ago if a company would sponsor a mod video I would have passed myself laughing and asked if you were crazy. I'm now passing myself with amazement.

Hey Walcom, are you keeping track of the score your blasters get on your indoor range? I actually think it's a very nice metric to measure similar types of blasters together, or at least against the top dogs. Pretty sure this modded MK 4 is one of the highest I've seen!

[@somethingsomething9081]

I'd really like them to release an updated muzzle extension that could connect to itself if you had two or more so you could just get an obnoxiously long barrel much like Coop did with all the modulas barrels.

[@tallon509]

This is why I watch, thank you for this video

[@alaeriia01]

I know exactly what's up. Dart Zone know full well what the MK4 is capable of, and they had to design it this way to conform to regulations. It's already pushong the upper bound of "toy", and adding the SCAR to the FPS barrel would make it a "sporting goods" item. They want to beef it up even more, but they can't. That's why they paid the Fuzzy Walrus to show us how it's done.

[@PetrolPaladin]

The DZP MK-4 is a 200 fps blaster, in the same way the Nissan r32 GTR had 276 HP.

[@haphazardninja]

[@sarahthompson9621]

Nice slug slym. Just picked some up. Also I wish that dartzone woulda used lighter metal similar to what saber did for the harrier.

[@FelixstoweFoamForge]

Nice to see DZ actually paying you to max out their offering. All things considered, I'll stick wiht my swift though. Reasons? Cheaper, especially living in the uk as I do. Better Aesthetics, (though that's personal choice of course), and finally, all I had to do was swap the o-rings, put the longer barrel and 1,8 spring in to hit 330fps max. Oh, I would take issue wiht the "lighter plunger=higher fps" idea. Jury's out on that. Anecdotally, my brassed Sentinel went from 170 to 230 when I had to replace the last part of the plunger with an aluminium replacement. Science to be done there. Maybe try the MK4 with the original plunger? I'd put money on higher performance.

[@rippsteakface]

[@edgardopereles9966]

[@vasiliathedemon425]

[@elementxxrider]

On a side note: we NEED to make a regulated fan competition that makes room for >500 FPS shooting blasters. The hobby may be getting to a point where hitting 100 - 150 FPS is starting to be poor performance (and standard propietary Nerf guns are basically kids initiation to the hobby, or Veterans platform for modifications).

[@BoardGamesBricksHobbies]

I personally don't like this escalation in the hobby. The higher the FPS cap, the higher the barrier of entry. Imagine some eleven-year-old showing up to a battle with a stock Motoblitz and getting trashed by some adult with a modded DZP Mk.2, that wouldn't be much fun. Yeah, you could give them a loaner to even the playing field, but do we really want kids running around with 200 FPS blasters? That said, with the increasing controversy around actual firearms, and seeing some of those tactical trends trickle into the hobby, maybe it's best if foam blasting is just for adults after all 😥

[@elementxxrider]

@@BoardGamesBricksHobbies hence why I pointed out the word "regulated", meaning that in the competition itself a high FPS is allowed, however (at least in my point of view) that doesn't mean we're going to bunch them altogether; of course we need to classify them properly so that there's, for example, a 70-100 FPS bracket, a 101 - 150 bracket, a 151 - 200 bracket and so on so there's little to no necessity of intentionally downgrading the FPS of a blaster. And of course this inherently means putting an age restriction cap on certain FPS levels.

[@BoardGamesBricksHobbies]

@@elementxxrider Understood. I just remember the first time I went to an event (which was as an adult, I might add) nobody communicated any of that to me. So I showed up with my stock Nemesis and got wrecked by people using NIC-style blasters and half darts. It was not a very welcoming initial exposure to the community.

[@elementxxrider]

@@BoardGamesBricksHobbies certainly understandable. But no worries, if we happen to do such an event I'll try to see to it that it gets proper and fair regulations so that every blaster wielder has a fair chance of winning regardless of the FPS.

[@spenceranderson4045]

It's like this in all the gun sports. Paintball airsoft. Technology improvements.When adults with money are playing they generally have the best gear on the field in any sport really but in these games it give a huge advantage. It is what it is. I always just got decent stuff second hand to even the playing field a lil bit. Kids play paintball too and the usual limit is 300fps
