The most affordable, reliable auto-springer available! | Zius BK2s AEB REVIEW

We are seeing a surge in injection-molded Automatic Electric Blaster (AEB) releases, and each one seems progressively better than the last. The Zius BK2s sounds like an iteration of a faulty predecessor (the BK1 + BK2), but don't be fooled. This blaster is superior in every way. And with barrel and spring upgrades, this is probably the best bang-for-buck AEB you can get right now. Let's check it out!

[@ShadowDaPk]

A Canadian group was one of the first to modify the BK-2S to take Talon

[@HyperShadow89]

Not being Talon compatible is certainly a choice

[@stuntmatt7124]

Reasonable priced AEBs, seems like a great addition to the Hobby. I hope you guys do well with them !

[@Snuffflux]

man, i'm so broke right now but i'd love to pick one of these up in the future. Ever since I saw the sweetheart storm I've been wanting to get my hands on an AEB and this seems like the first one I can actually maybe afford!

[@benlam419]

I'm waiting to see if the Talon mag compatibility mod for the BK1/2S will be more mainstream. Then after that, what other mods that can supprt the platform.

[@codyrasmussen5797]

Would love to see the bk1s in the shop

[@delvercetti8930]

Not likely, that version has a lot of durability issues from what I hear.

[@dancarthen3634]

why? the break in 5 mins

[@codyrasmussen5797]

@@dancarthen3634 if you watch monkey mods video on them he actually says he thinks both are the same reliability wise but has more pros for the bk1s and it might be upgradable in the future. I know most people would be happy with 166 fps but I'm always looking for more

[@breathingbackwards949]

@@dancarthen3634You’re thinking of the original bk-1 not the new bk1s.

[@KamenBeyblader362]

Or at least a interchangeable longer barrel and hand guard For the BK_2s

[@jaws_drinks_water389]

This is actually so cool

[@V7I-theseventhsector]

i want more than anything is the gearbox, JUST the gearbox. i want to make my OWN 9un around that GB. i LOVE airsoft and have made a number of custom airsoft 9uns and would LOVE to do the same with nerf!

[@DefinitelyNattox]

If it was talon compatible and could be modded to be 120 FPS, I would consider it.

[@knuttz86]

If i still went for games I'd certainly want one in green with a tiny picatinny-mounted fedora to go with that orange front-end.

[@NightFury-jd8ce]

Thanks Luke!

[@valkorsimpson4525]

This blaster not being talon compatible is a huge miss and I don't see it being very popular for that reason alone. It's a real shame, could have been a solid option.

[@Brick_Bunker_Official]

Literally why I'm not going to buy one

[@David_Randall8108]

I really wanted Momentum, but I feel like AEBs are just better than flywheelers. It makes me a little sad, but also excited.

[@classicforreal]

Dear Luke, While we appreciate the barrel safety slip cover, the Number One piece of feedback I keep hearing on all the Discords is that people are expecting a more "custom" option from OoD (and many people are making their own)

[@outofdarts]

We would love to do a custom colorway in the future, but the cost and demand (MOQ) are both currently out of reach.

[@NerfimusPrime]

Many games would hard cap out this gem. How simple is it to get to the spring? A 120, 150, 180+ - 200 fps spring would be needed for it to have a home at most games for many of us.

[@rickrebouche354]

Id be really interested in a talon compatible printed lower for it if you made or licensed one. Also what scars/bcars is it compatible with? The Dart Zone ones maybe?

[@blendervendor2220]

I think it's a good idea to have both in the store yes. I really want to design my own front muzzle for it that isn't so... milsimmy. It's an absolutely perfect budget option becuase all the others are super expensive. I there a potential in the future for upgrade or spare parts for it to be stocked (gears, barrels, springs etc)?

[@prime-eight]

Any plans to stock the BK1S?

[@generousghibli6031]

Proprietary mags are a no-go for me. Blaster makers need to take a note from the real steel industry. The common mag types are the one to use.

[@TommyGee.]

Do you think Nerf Pro line will include an AEB?

[@johnvale9337]

WIll the BK1S's be available as well or is the BK2 be the only one available for the near future?

[@dancarthen3634]

the BK1 is prone to breaking

[@frogsbutfrogs]

​@@dancarthen3634there is a difference the bk1 is the og version. that breaks, the bi1s is a new larger ve w on if this. any people aren't smart

[@koenkooiman1490]

Do you plan on selling up and downgrade springs for it in the shop? I'd love to be able to switch my bk1s between 150 and 200fps

[@outofdarts]

We've already done some testing, and springs will be available soon!

[@rickrebouche354]

​@@outofdartsthanks, I was going to ask the same!

[@HBOhomo]

when i can land a job, i would honestly love one of those but with a longer barrel and painted a stone greyish blue like the AAC Honey Badger. would that be possible at all?

[@Snuffflux]

I've got a job but all my money goes to rent :( literally gonna have like 90 bucks to my name by the end of the month. love that idea though and would also be interested in making it a little more mil-simmy, but I doubt that's the direction Luke will wanna go. If anything I expect to see more toy-like AEBs to start cropping up at a lower FPS to appeal to a wider audience.

[@HBOhomo]

@@Snuffflux i kind of figured that to be honest, but it was still something to ask. i would still like the longer barrel, but if not, i can always just make one and paint this. its no biggy,

[@dzpdave1649]

Great video, I was wondering how was it firing? Non bamboo darts because I know the sweetheart storm really didn't like darts that were not bamboo style.

[@outofdarts]

It did just fine with normal darts! Possibly this is due to the way the barrel is chambered.

[@GMichaelBridge]

@@outofdarts i found xyl darts to be a bit too skinny and not air seal in the bk1s barrel, but i may have just gotten a bad batch w/ my unicorn

[@geiarmchannel135]

Canada group already Talon modded and able to reach 200 fps !!!!

[@cvorammlied]

I wonder how easy it will be to tune the blaster down towards 110ish fps.

[@outofdarts]

Really easy. It can take cut-down versions of our Nexus Pro X springs. with an easy spring access plate underneath the thumscrew on the stock

[@ghijkl]

Are these for adults or kids or both like airsoft?

[@ToxicAtom]

Nonflared, non-talon magwell is the death sentence on this one for me. Until a decent mod to fix that comes around, I think I'll pass.

[@MonarchNerf]

Doesn't fix the 2nd one but Monkeemods currently sells tons of stuff for the 1s and 2s including a flared magwell!

[@ToxicAtom]

@@MonarchNerf sounds dope, I'll have to give it a look, ty

[@quasistellar]

Do the BK1S and BK2S fit the same physical size battery?

[@outofdarts]

I believe so? The BK1s may take the other size of 1100mAh that we have on the shop that's built to fit inside a buffer tube.

[@GMichaelBridge]

@@outofdarts bk1s takes a buffer tube 3s battery, not sure if the 2S can fit that since its longer.

[@kerry848]

BCFF for talon mods 🇨🇦🇨🇦

[@Beegrene]

So is this an electrically driven springer? Like the old Nerf Stampede? I wasn't aware that style of blaster was making a comeback.

[@ernestuy7128]

Yup, those are usually reserved for airsoft since the projectiles are lighter and there’s much less of a demand on the internals. They’re also more expensive than flywheelers and the only improvement is accuracy, which commercial blaster manufacturers that market towards children don’t really care about.

[@GladlyKillmore]

Metal gearbox, airsoft gear and motor upgrades plus cosmetics. Yeah it’s not meant to look like a childish blaster, it’s supposed to look like it is. An SBR platform for the players that enjoy its silhouette. (Edit) the gearbox itself is not metal, but the “drivetrain” and bearings are. Which is a huge plus. The gearbox not being metal may pose as an issue, but it’s bolted in, so that’s doubtful. But we shall see as we mod!

[@rickrebouche354]

I'm not super worried about the gearbox being polymer as long as the gears and bearings are metal. It taking airsoft motors could be really cool.

[@TMDroidX]

I dare anyone to fire the BK2s with a proteus pack.

[@saberwing7930]

I find it rather annoying that the magazines are proprietary. Especially since they don't even do something like last round hold open. That would be a very nice feature. Also, it's really a shame that @outofdarts did not mention how you shut off the blaster. To me, it's an annoying and needlessly convoluted process. I think that needed to be in this review.

[@The_Mess85]

That sound of firing is just beautiful. Unfortunately can't buy it anytime soon, as have to pay for an ADHD diagnosis >_< And also have to buy a AMD Ryzen 5800X3D CPU...

[@quantumsniper9433]

You might be able to meet the MO for a new colourway by asking the singapore and aussie retaliers to share orders. Singapore/Aus also arent big fans of the black handguard/stock. Many people ive seen in SG nerf groups either paint, use the decals made for the bk1s or just 3dp a new handguard for their bk1s/bk2s

[@zenden9]

The handguard and buttstock for BK1S are airsoft/ gel blaster compatible. You can ready just swap out with a metal URGI 10 inch sand color handguard. Making it less intimidating with the sand color and yellow receiver. Buttstock too, swap with a marine sand color buttstock.

[@DanielGonzalez-ok5xd]

Luke can I work for you 😅

[@skeemeastwood9075]

$160 doll...(keeps scrolling youtube)

[@Heron54]

$160 is not that affordable 😭

[@samuellee7990]

it looks like a tec-9 from cs

[@Maegnas99]

Can we please stop making our blaster toys look so similar to americas favourite murder tool?

[@tomfoolery4024]

It's not just pressure fit, people have already made a proper release. Please don't spread misinformation, thanks

[@outofdarts]

We weren't aware of someone making a talon-compatible mag release until after this video had already been filmed and edited. In fact, we are looking into the mod ourselves, and may showcase it in a future video.

[@frogsbutfrogs]

you gotta realize that these videos are recorded and edited before they are published it ain't being made the same day or week
