How to Make: Airsoft Masterkey Shotgun Attachment

[nightXriderZ]

whats the range on this?

[silverballer1911]

call of duty sucks

[doobieboy23]

Make a sniper

[200130769]

lol i love when cod ppl call under barrel shotgun attachments masterkeys lmao

[waderobertsNChunter1]

@200130769 yes thats in cod but that is what its called masterkey its the key to the city

[TheSpawner855]

@200130769 Underbarrel shotguns are called masterkeys because they were used for breaching doors without having to switch between weapons.

[Mad21Skilz]

@GreekGadgetGuru you use alot of pvc or what ever in these invention dont you

[cenzo227]

i really like the vid and im big in this stuff but can u tell me a way to make it without the co2

-thanks

[DragoonRaidfilms]

IT DIDNT EVEN BREAK THE PAPER!!!!!!!! :(

[PoofDuddy]

"if you look close you'll see the holes in my head.."

[THATpbGUY14]

If you could can you send instruction to build one if not ok

[THATpbGUY14]

If you get the right PVC than you could make one for paintball.

[Odinfang]

Be great to take this exact same tactic, but instead of making it an attachment, a full blown airsoft shotgun, with stock.

[sarahooxo]

show us how to make a grenade next?

[60inchwilly]

did u get this off red jacket?

[LastResort0011]

Cod fan...

[GhostOfTheAngels]

Guys, why would you want the FPS if it can't go through paper from 5 feet away?

[Trigg3rFing3r007]

@GhostOfTheAngels lol most likely

[GhostOfTheAngels]

@Trigg3rFing3r007 He was shooting at paper though lol.

[ThatOneGuy1044]

can you please tell me where i can buy the co2 bike pump in your next video please i been looking everywhere and i still cant find it.

[xXMapleVodkaXx]

OR just take off the handle of an airsoft shotgun.

[MrGodlikeGaming]

Ok i have an aluminium Can the other errrrr nope ;D

[ThatOneGuy1044]

Can you try to make a law out of your idea cuz i found out a way how to and if any one wants to know how to make it send me a message to my account and it all depends on how many people want learn how to do it. And thanks GreekGadgetGuru for making this video cuz if it wasnt for you i wouldnt have came up with my idea

[lonestar3164]

@ThatOneGuy1044 put a ball where the bbs go?

[burnsagittario3368]

can you use 12 gram co2?

[drac00n]

this rather looks like a dildo, more then it does like a shotgun..

[sarcastro308]

gee.. thanks. u told it what it is and how it works. now if only i knew how to make one... *facepalm*

[tconnyankee88]

whats the trigger

[MichaelEppinetteTV]

@tconnyankee88 its an attachment.

[bamahacker01]

I guess you like orange?

[allthingsawesome2]

cool

[flameingawesomeness5]

i aint got on money and i need bike pumps

[avatar6091]

what if you'd replace the balls with fishing lead balls :D

[1990cujo]

put a nerf dart in there

[skull02892]

wow i want to make this mount it on a staff and attach housing insulation that is shaped like blade on the opposite side and use this in an air soft war... its cool because you can make extra barrels/mags that you can swap up. i think i would consider using a manual pump though, never had luck with co2... thanks for video

[R3B3L808]

Cool it works like a beauty

[MannyFresh1x]

Now try metal bbs and go to bb park lol

[codmw2killa23]

im gona try to make it

[Likeabossinamerica]

those arent bb holes they are pen holes

[mpmurphy2014]

@GreekGadgetGuru

You'd get much more power behind the BBs if you added some sort of wadding behind the BBs to push them. all it takes is a balled up paper towel to have a harder shooting shotgun

[MrShadowsalem]

you need to do what kipkay does

[MrShadowsalem]

ok where are the instructions?

[LeGiiTxCrAzZy]

what the fps?? if its decent im making one

[GreekGadgetGuru]

@LeGiiTxCrAzZy Tell me how to find out and I'll let you know. I guess Distance/Time?

[ghostmarines]

@GreekGadgetGuru find a airsoft fps meter, alot of airsoft stores should let you test the fps for free.

[XlMckeonlX]

@ghostmarines chronograph?

[GUNSFOREVER1]

@GreekGadgetGuru Chronograph

[TheAnonymoususer5]

@GreekGadgetGuru Get a chrono? (Not to sound like a snotty person telling you what to do, but as a casual answer )

[JAEProductions1]

@GreekGadgetGuru You can get a thing called a chronograph

[Bronmonze96]

@GreekGadgetGuru if you didnt find out yet, google "poor man's chrono"

[MrDevin712]

@GreekGadgetGuru Chrono is what its called! :)

[xboxplaya124]

@GreekGadgetGuru got to go to a airsoft or paintball place instead of having to buy one, unless one of your friends or family has one that works as well. i do do airsoft so please respond as soon as possible ive already got the parts set out for it. 

[Blxez]

@GreekGadgetGuru well shoot a friend at about 10 feet away if it hurts could be around 200-300 fps

[kaestar5]

@GreekGadgetGuru chrono



[nomnom451]

@GreekGadgetGuru

to find fps stand about ten feet away from something time how long it took to hit your target and then divide the time by ten

[SuperMw3killa]

@GreekGadgetGuru feet per secand

[ikaninjau2]

@GreekGadgetGuru I guess you don't have a sensor, for FPS so just say how far it goes (with one shot loaded) and if it stings well.

[MrPossable]

@GreekGadgetGuru chronograph

[AkimoTheropy]

@GreekGadgetGuru get or make a chrono machine to test the FPS/RPM of each BB, and if you do please test with both .12gram and .20gram it would help alot

**DO AN AIRSOFT (THROWN) GRENADE VIDEO PLEASE**

[TrophyStudios]

@GreekGadgetGuru you can buy a machine that measures it

[MrDevin712]

@GreekGadgetGuru chrono google it.

[JoeBozz95]

@GreekGadgetGuru Its Feet per second

[TheLifeOfTommy]

@GreekGadgetGuru Its called a chrono you noob.

[kittykamakat]

@GreekGadgetGuru Fps Stands for "Feet per Second" so yes, you would measure it as distance/time, hope I helped.

[JoshuaDaPeck]

@GreekGadgetGuru Get a chronograph

[larryandpike2]

@GreekGadgetGuru he it a very simple way, does it hurt when shoot, yes then good enough, bruises then great, just breaks skin+ bruise perfect

[Biggerthenbetter]

how exactly does the co2 pump thing work? is it refillible and if so, do you pump it or wat? and haha i know this question i don't know to much about thsi

[Biggerthenbetter]

[TheJoshuapaula]

omg the 1st guy to make something off of callof duty

[ezio4life99]

does any one no were to get an airsoft gun ive looked on ebay they dont have any :( suggestions any one?

[TheArzonite]

@ezio4life99 Have you even tried for looking them? write "airsoft guns" to google... dumbass...

[pyrosimple]

Cool, but I am sure it would work much better with a barrel and wadding for the BB's.

[chevy92blue]

is it a one shot then new co2

[TheJasonbmx]

Thats awesome I think you should make lots of shells so you don't have to keep reloading

[janusafghanus]

Now in every Russian happy meal!

[stormleo88809]

@janusafghanus thuumbs up fail.

[duellarea]

is it annoying to change the gas tube?

[grassface1]

awsome



[VanHalenWorshiper]

this is the result of too much video games

[Lastdoodleman]

Very cool but it will look better if it had a hand grip or something

[DistantShrimp]

to improve power distance and accuracy, you should add a shotgun wadding there cheap a buck for like ten and there reusable, or make your own. :)

[MasterBassoon]

I know you just showed us how it works and what u used. But can u make a step by step how to of how you made it?

[beatdownmaster9]

Lol, Attach it to your flame thrower and who ever breaks in shoot em in the eye then light thier ass on fire.

[Anarchyffan]

You'd probably get higher FPS if you only sealed the side closest to the output valve

[andreytheawesome]

Hey not bad but I will stick to compound bows since I am 12

[x775xNERD]

buy*



[x775xNERD]

where do you but the bike pump extension tubes?



[TheHotrider15]

nice paper penetration there hahaha



[snayperskayaKP]

r u 100% percent black ops inspierd

[GreekGadgetGuru]

@snayperskayaKP Nah, I just go with whatever is the most popular COD game. 

[EpicWin4231]

@GreekGadgetGuru It's 'cuz COD is more badass than real life

[kllemall1]

@snayperskayaKP lols COD stole this off army of two easy way to find out fps is go out and buy a chronograph

[Butterfinger109]

@kllemall1 lols. it's actually a real thing. not just from a video game.

[simoncrowley005]

could i change the co2 pump to a normal pump pump lol any way so i pump to build up the pressure per shot would that still work

[GreekGadgetGuru]

@simoncrowley005 Maybe. One pump per shot wouldn't be enough. There's probably a way to make a valve that opens once enough pressure is built up. But you'd have to create a separate chamber for the air to pressurize. The bast disc (aluminum foil) that I talk about is sorta like a valve that allows pressure to build and then ruptures with more force than just the air from a CO2 cartridge. If you could make a re-useable valve to release pressure once a certain PSI is reached you could do this : )

[simoncrowley005]

@GreekGadgetGuru so if i got say a ball valve inbetween the pump and the shotgun then pump like 30 times the released would that work

[GreekGadgetGuru]

@simoncrowley005 Yea, I just don't know how effective it would be : /

[simoncrowley005]

@GreekGadgetGuru thxs

[Stijning]

i'ts called a masterkey because it opens every door XD

[noname19111]

he makes it look so easy i tried and i got 5min into it and threw everything away

[22Drews]

@MrNother23 oo sounds awesome can you show me

[Redskull1312]

You like call of duty black ops or ? When yes and you play on PC add me in youtube than me say your steam name ^^

[bdawg13243546]

wait how do you replace the co2 cartirige

[aMpiiEn3rGYii]

just imagine if he gets his hands on some real guns how much shit he'll do u call him a geek now

[emceeginger]

its called the master KEY for a reason and it was used to breach doors so there is no reason to have one on your airsoft gun anyway but i do like the idea of it

[supe9sniper]

Cool i have a challenge for you that would really be worth it an airsoft claymore mine its your choice but i would definetley try it!

[ianster0102]

MAKE A TUT MAKE A TUT MAKE A TUT MAKE A TUT PLEASE

IM SUBING

[conjuntoestrella123]

How Do You Switch OUt The Co2 Tanks?

[daytdog]

You need to

Make a tutorial

[w4rdog961]

dude u should make a toutorial i know u basically just explained everything but wat did u use to screw in the co2 cartrige to the bike pump

[jooel33]

Try paper towels instead

[lookamyname1]

now clean it up.

[NORFproductions]

if ur greek, shouldnt you be wearing a spartan helment????????????

[KillerRed9]

@NORFproductions I just facepalmed at this comment. Really? How much fail could you possibly give off?

[NORFproductions]

@KillerRed9 Alot.

[KillerRed9]

@NORFproductions Oh, okay.

[pyrosam7]

how many shots can you get from the same co2.

[Hulianomarkety]

how far do the bbs go without a barrel? im making an m203 and i am using an aluminum pistol barrel, but it lowers the number of bbs i can put in. i tried without a a barrel and it didnt work well. of course, i didnt put aluminum infront of the bbs...

[Vacousknave]

Will metal BBs work

[IisAtomik]

How does it attach to a rifle

[GreekGadgetGuru]

@IisAtomik  It's up to you! I'd prob use black electrical tape, maybe Velcro with an adhesive side for quick removal. Hose clamps work too!

[MrNother23]

@GreekGadgetGuru hey man I've made a flamethrower/masterkey/bayonet­/crossbow. It's absolutely awesome. 200yd infrared laser, 43yd blacklight in which both are screwed into a wooden dowel. crossbow is compact being semi-automatic with spring/pressurized reload in chamber. Bayonet is basicall a small reciprocating saw I made, flamethrower was based off yours but i added a fireproof choke to it to shoot it farther, and masterkey was my own design which shoots glass shards. it looks legit too.

[DeathDart2k]

@GreekGadgetGuru or take a rail mount clamp for 20mm weaver and super glue it to the top of this so you can slide it in any airsoft rail

[flaminhott2010]

@GreekGadgetGuru Does the bike pump accept standard 12g CO2 cartridges or do you have to buy special ones

[radimaida]

@IisAtomik i would use a rifle scope attachment

[salaizrm]

Try making a high powered paintball gun! I would love to see a powerful sniper rifle!

[vaultboyhunter2077]

do u pump it or use co2 for every burst?!?!?!?!?!? or is the co2 cannister just an air holder?!?!?

[GreekGadgetGuru]

@vaultboyhunter2077 You use a quick burst of the CO2 cartridge, there is no pumping for the air.

[vaultboyhunter2077]

@GreekGadgetGuru can you modify it to use a pump?

[TheCommentGiver2000]

Really are u greek?

[Jimmy99Nas98]

are you greek ??

[GreekGadgetGuru]

@Jimmy99Nas98 Yup, but born in America : )

[Jimmy99Nas98]

@GreekGadgetGuru yy i am greek and i live in greece !

[lolcatzman1]

Hey yeah i was also wondering the same thing. what type of hose it that. great video btw

[airsofter123100]

has anyone else built this do they know?

[airsofter123100]

what is the exact name of the hose you used. i have looked all over and couldnt find one that works with my pump(the same one you bought), could you please tell me where you bought it

[Amazing1h]

Holy s**t! Cant u guys just respect that its a cool invention for airsoft!

[Ballisticboy99]

Rman235 they are talking about this Airsoft masterkey model in real life uses. If Antibes the dumbass it's you for not paying attention.

[hopyfullyapro]

That you blue for being the thir personto tell me this but does this actually shoot off door knobs

[Rman235]

you guys are dumbasses its ment for AIRSOFT not for actual breaching operations

[hopyfullyapro]

FYI this is not a masterkey because it doesn't shoot of doors, correct me if I'm wrong in a respectful manner please

[hopyfullyapro]

Thanks for that special insult at the end i can already tell your have no respect and probibly spend most of your day on the internet and I was already corrected

[hopyfullyapro]

You know it's not actually called a masterkey, that's just what call of duty calls it

[aerodynamicband]

@hopyfullyapro Knights armament sells a remington 870 masterkey. yes that is really what they are called. but their intended use is as a breaching shotgun with frangible slugs to shoot locks off doors

[gar24207]

@hopyfullyapro it is called a masterkey its used to bust open doors...dumbass

[bluesy92]

@hopyfullyapro Actually, "underbarrel shotguns" or whatever you call them are actually called masterkeys. The reason behind this is that during breaching (shooting a lock off of a door with a shotgun) the person breaching would take a few seconds to switch over from their shotgun to a rifle. So, they mounted the shotgun underbarrel to allow faster weapon switching. The "masterkey" got it's name because it is for opening doors.

[CODallnightlong]

@bluesy92 Yeah it was obvious that two people had already told him that.

[hansthekraut]

Hi I had a similar except I wasn't going to use the bike pump hose, and mine was just going to be an airsoft sniper. I was looking online, and people say that these .12 gram co2s that I have hold arround 800 psi, and I was wondering, were is most of your pressure held in this?

[farmboyEN]

great idea how many shots can u get?

[diycool]

Hey man it's diycool! I saw the title and wasn't quite sure what it was, but now that I watched it, this thing is awesome. I've made simple PVC airsoft shotguns, but the foil seal is brilliant! Thanks for the vid and keep it up!

--diycool

[snowmanjr25]

cool but make a video on how to make it

[TheAwesomeparker]

dude i saw you post a comment on one of my subscribers i clicked on your channel and this is cool

[DarkDeviator]

Hey this design is really cool and i wanna ask can use your idea in one my airsoft gun project ?)

[clonewars999]

wow, cool!

[Erick12073]

Awesome
