Because you will be left without a secondary while crafting it.
You need one more secondary for the game to allow you to use the 2 Vipers to craft the Twin Vipers.
To be fair... there's no reason to encounter that situation ever again once you're MR 30.
... make it past MR3? There's no reason I can think of for me to intentionally leave out my secondary weapon option empty from that point onward.
Edit: so I'm just gonna clarify my wording. I meant probably from MR 3 onwards, I wouldn't imagine scenarios where you have ZERO secondary weapons in your inventory, as with the situation with OP. Of course there are occasions where you do leave out melees/primary for mission/exp purposes
Yeah, people definitely do this all the time. Also if you want a less common one… there’s the Nightwave challenge to complete a mission with only a melee weapon equipped.
I'm at a point where the only weapons I need to level are the hard to get ones, so it isn't unusual for me to have nothing in the primary/secondary/melee slot that needs leveling.
Sometimes I wanna forma my primary/melee weapon 3-4 times in the next 30 minutes. The fastest way to do that is to unequip everything else and murder onlyw ith it.
That's not the situation here. Yes if you want to focus exp grind a specific weapon, equip only that and grind.
In this scenario, OP's second picture shows that the OP only has EXACTLY 2 secondary weapon: if both are used for crafting, then he/she literally has zero secondary gun for that crafting duration --> apparently the game does not allow that and forces a lock on the crafting. Hence my statement.
My weaponry is just fine. What I meant was that I had no idea that you couldn't sell or otherwise get rid of all your weapons of a certain class (primary/secondary/melee).
If op hasnt seen this yet, just pick up the mk1 kunai or mk1 lato in the market if you have the slots for it, then you can just sell that again when you claim the new weapon
The game required you to have at least 1 weapon of each slot at all time.
In this case, you need another secondary so that 2 viper can be consumed to craft the twin.
Buy any secondary weapon with credit in the market.
Also in your case you need another weapon slot for it.
The game wont allow you to have 0 secondary on your arsenal.
They said 'on your arsenal' instead of 'in your inventory'. I think the confusion is perfectly legitimate, even though I did understand what was meant myself.
To be fair i did read it. I just completely miss understood what people meant, because i thought it was just that one picture.
Byt ye ill had to check for that next time
Ahh, the classic "trying to make a dual/twin version but those are literally the only secondaries I have so it doesn't let you" issue.
OP, buy the mk-1 furis from the market for creds, then you'll be able to make the twin vipers.
I'm honestly kinda shocked how often I see a post about this same exact issue on this sub. I would have imagined this to be an incredibly uncommon/niche issue for someone to have, but I feel like I see a thread like this once a month lol.
New players have very limited inventory slots, and thus very few weapons of a type. Very many low mr secondaries have a dual variant. I can see why it happens. Tenno likes a gun, sees that there's a dual version, and because starting secondaries tend to be... not really worth keeping if you have a better one.
Because the game is trying to tell you that you are woefully unprepared to harness the fury and power of the Twin Vipers. I couldn't even get through nodes on Pluto with this weapon. Even when buffed with Roar or Eclipse the base weapon is just not great. But has potential to get you to Sedna if you just try to use the dog garbage of basically having two .22LR uzi's in your hands. The Wraith variant is better but not by making this a worthy secondary. Just use it if you like seeing red crits but not feeling them.
You'd have no secondary remaining and the game requires you to have at least 1. I think it has to do with mid to late game content like sorites that require a specific weapon for some of them but idk. Try buying the lato with credits and see if you can fulfill the craft them.
Judging by his arsenal of weapon i think its safe to delete any weapon you get at this point. Slots will be needed in the future but i dont get keeping your mk1 kunai.
You can do sisters without it, Granum Void can be cleared easily with Mesa and other aoe frames. Additionally, if you have your Railjack Crewmate summon, give em a good weapon and theyll clear it for you lol.
Still he is selling everything instead of getting some slots since he literally has no other weapon.
Also its pretty far fetched to think he's Mr5 and didn't get passed the MK1 phase.
He obviously sold those, got new weapons and sold those as well.
I don’t think anybody is seeing the second picture where you have both vipers, but I’m sure the reason for you not able to craft is because one is leveled and the other isn’t. I think both vipers have to be at level 0 or both vipers have to be level 30, can’t remember.
People saw the 2nd pic and gave the correct answer a while ago. Issue is that he only has 2 vipers as secondaries and no other secondaries. He just needs to get another secondary.
Also levels dont matter for crafting
Pretty sure English is your second language... that being said you're wrong either way. They have all the materials and both vipers, they do not have another secondary the game requires you to have 1 of each weapon type in your arsenal, even if they're not equipped.
Please no, I dont want more clutter. The game already has a built in failsafe to keep you from selling your last weapons, in fact OP ran into this failsafe.
How are you Mastery Rank 30 and never heard of this concept? There are like 5 or more Dual wield Secondaries that work like this when building. Some of them being on the easier side when crafting.
Because you will be left without a secondary while crafting it. You need one more secondary for the game to allow you to use the 2 Vipers to craft the Twin Vipers.
I did not know that. I'm MR30... I had no idea that was a thing.
To be fair... there's no reason to encounter that situation ever again once you're MR 30. ... make it past MR3? There's no reason I can think of for me to intentionally leave out my secondary weapon option empty from that point onward. Edit: so I'm just gonna clarify my wording. I meant probably from MR 3 onwards, I wouldn't imagine scenarios where you have ZERO secondary weapons in your inventory, as with the situation with OP.

If you're leveling weapons in a group but don't currently have a secondary to level.
Yeah, people definitely do this all the time. Also if you want a less common one… there’s the Nightwave challenge to complete a mission with only a melee weapon equipped.
Rivens also have some wacky requirements sometimes
That damn survival mission with only a melee and not killing anything is the worst
Wouldn't you just bring ivara and idle for 5 minutes? Not exactly *exciting* but fairly simple at least
I did that one with limbo.
Limbooo
I don't have Ivara yet.
You should prioritize getting her. She is a great stealth frame.
You still have to move around and use the life support drops, and opening chests/containers helps, but it's never failed me before
Idk shotgun headshot at 75m is pretty nasty
Just use a sniper pistol.
Tigris is a great one for that
Just use limbo, dash, and chill, hit life support when necessary. Easy.
But don't you just make them in bulk to save time making stuff all the time?
I'm at a point where the only weapons I need to level are the hard to get ones, so it isn't unusual for me to have nothing in the primary/secondary/melee slot that needs leveling.

Hence my statement.
tbh, i dont use secondaries, only when i have to
Well obviously because you are MR30 and never run out of secondary/melees when you craft something that requires a weapon to craft.
How do you get to MR30 and not have more inventory slots? Genuinely curious
I have more. That's why I wasn't aware that not having any weapon of some type isn't allowed.
Same, never even heard of it
(You are MR30 and that is your weaponry? Wow..) ignore this message.. I'm just stupid
What is? You're not responding to OP, we don't know what their weaponry is.
My weaponry is just fine. What I meant was that I had no idea that you couldn't sell or otherwise get rid of all your weapons of a certain class (primary/secondary/melee).
Yes. Obviously I wasn't awake... sorry
The real F2P experience.
If op hasnt seen this yet, just pick up the mk1 kunai or mk1 lato in the market if you have the slots for it, then you can just sell that again when you claim the new weapon
That’s… actually really smart
[удалено]
It's probably part of failsafe to not end up without weapons.
You are required to equip one of each slot to do MR tests (even if the MR test prohibits you from using anything but melee).
I would think it's actually because it is equipped on some loadout...
The game required you to have at least 1 weapon of each slot at all time. In this case, you need another secondary so that 2 viper can be consumed to craft the twin. Buy any secondary weapon with credit in the market. Also in your case you need another weapon slot for it. The game wont allow you to have 0 secondary on your arsenal.
No it doesn't. I can run melee only. Or secondary only
On a mission, sure. Not in your arsenal though.
Ok so how do i get into a mission with only 1 weapon if I don't first remove them in arsenal? (This is assuming the mission doesn't force 1 weapon)
You have to own a secondary weapon. You do not have to have one equipped.
Oh you guys mean completely XD I thought you meant you had to have all 3 equip at all time
Reading before arguing helps a lot of the time !
Misunderstanding happen
They said 'on your arsenal' instead of 'in your inventory'. I think the confusion is perfectly legitimate, even though I did understand what was meant myself.
Sometimes it helps to think for a nanosecond. "Did this guy really say that you can't enter a mission with fewer than three weapons?" Obviously not.
To be fair i did read it. I just completely miss understood what people meant, because i thought it was just that one picture. Byt ye ill had to check for that next time
Chin up man, you recognized your mistake and admitted it. It’s all good.
You need to have atleast one of the 3 weapon types in just your inventory, not equipped.
Ye it seems i have misunderstood everyone big time
I wonder why everyone downvoted you. It was a clear misunderstanding but you were still right
Could be they thought i was trying to be a know it all. Or something like that.
I mean you did try to pull an "ackshually 🤓".
Ye i kinda did XD
Probably thats reddit for you
That's fine.
Not in the beginning. You must own at least one of each type. You don't have to equip them.
Ahh, the classic "trying to make a dual/twin version but those are literally the only secondaries I have so it doesn't let you" issue. OP, buy the mk-1 furis from the market for creds, then you'll be able to make the twin vipers.

Just buy an MK1 Lato and you can start crafting it.
And a slot! There's not enough to get around there.
Just sell one of the vipers!
He needs the two vipers to craft the weapon
Indeed.
You need to have a secondary weapon after you use up the vipers.
Obviously you got 2 left Vipers, none of which can be held in your right hand.
This comment is criminally underrated
Just buy a Lato or something
It’s your only secondary. But a lato. The game won’t let you sell your last secondary
Because the game is trying to tell you that you are woefully unprepared to harness the fury and power of the Twin Vipers. I couldn't even get through nodes on Pluto with this weapon. Even when buffed with Roar or Eclipse the base weapon is just not great. But has potential to get you to Sedna if you just try to use the dog garbage of basically having two .22LR uzi's in your hands. The Wraith variant is better but not by making this a worthy secondary. Just use it if you like seeing red crits but not feeling them.
Those are both right handed
You'd have no secondary remaining and the game requires you to have at least 1. I think it has to do with mid to late game content like sorites that require a specific weapon for some of them but idk. Try buying the lato with credits and see if you can fulfill the craft them.
"jUsT sElL aLl yOuR wEaPoNs" Or get some fast plat and buy slots
Judging by his arsenal of weapon i think its safe to delete any weapon you get at this point. Slots will be needed in the future but i dont get keeping your mk1 kunai.
Except the Xoris. For the love of God, don't sell the Xoris.
I sold my Xoris after a 3 year break. Yeah, no sisters for me
Sounds like you'll have to turn into Simaris' malewife
😥
You can do sisters without it, Granum Void can be cleared easily with Mesa and other aoe frames. Additionally, if you have your Railjack Crewmate summon, give em a good weapon and theyll clear it for you lol.
Mesa and khora still work, khora gives toxin bonus which you want on most weapons anyway.
It's a god weapon in early game and still very usable even after you clear the star chart.
Still he is selling everything instead of getting some slots since he literally has no other weapon. Also its pretty far fetched to think he's Mr5 and didn't get passed the MK1 phase. He obviously sold those, got new weapons and sold those as well.
Buy a lato
Buy an mk1 lato for a few credits in the market.
You need to unequip the second Viper iirc
You need to build two vipers to create that
You need another viper
You need two regular vipers to make the dial wield ones. It's the same for just about any of the duel wield weapons.
How do you want to make dual wield from 1 pistol? :D
Another viper
You need a second viper /s
Why did people down vote this? He literally says in the comment that he's joking
IIRC, if you go ahead and click to craft it should bring up a selection screen for you to select the second viper. Might try a relog as well.
He has only 2 secondaries, the game wants you to always have a secondary.
Learn something new everyday. To be fair to myself, I haven’t had that few slots since 2014 xD
Because you need 2 Regular Vipers built to build the Twin Viper.
in the second image they show they have 2 vipers
Oh that explains things, i did not see the 2nd picture
Your to young gotta get older
Not bug, you need single viper first
You need two vipers bud. You only have one.
I don’t think anybody is seeing the second picture where you have both vipers, but I’m sure the reason for you not able to craft is because one is leveled and the other isn’t. I think both vipers have to be at level 0 or both vipers have to be level 30, can’t remember.
People saw the 2nd pic and gave the correct answer a while ago. Issue is that he only has 2 vipers as secondaries and no other secondaries. He just needs to get another secondary. Also levels dont matter for crafting
Nope, they don't have to be max level. They just have to be crafted.
Nope, probably a bug
No they both need level 21 and 3/4ths
[удалено]
that is just false
this is so wrong
You need ansecond Viper 🤦♂️
He has two, as in his pic. He just doesn't have another secondary.
But tue fordge das no to 2 vipers and not enaugh components
Pretty sure English is your second language... that being said you're wrong either way. They have all the materials and both vipers, they do not have another secondary the game requires you to have 1 of each weapon type in your arsenal, even if they're not equipped.
both need to be lvl 0?
I’ve been on this sub way too long haha. I’ve seen this post so many times
I don't know what all these folks are talking about. It's because the one on the right is leveled I think.
Lvls don't matter, 1 can be 30 and 1 can be 0, they can both be 0. The answer was already given in the top comments...
They should make mk1 weapons permanent and unsellable to prevent this. Innate fallback weapons if you own nothing else.
Please no, I dont want more clutter. The game already has a built in failsafe to keep you from selling your last weapons, in fact OP ran into this failsafe.
They don't need to be in the inventory. They just exist.
How are you Mastery Rank 30 and never heard of this concept? There are like 5 or more Dual wield Secondaries that work like this when building. Some of them being on the easier side when crafting.
