Well now I know why you were asking for things to fist real hard! This makes me wanna do more stuff with powder actuation.... 10/10 build 10/10 video 10/10 gratuitous coconut violence perfect score bro

Cool video! 👍 Thanks for making my Ramset feel so... inadequate.

I've been wanting to turn my explosive bat into an explosive hulk fist, but seeing this I think I like the AR-15 form factor better :) Awesome to see it punching through those bricks. Nice work!

10:56 “oh nooo, we’re locked in!” *you are literally holding the most tactical breaching tool in the world in your hands*

I spent the night trying to make it Semi automatic.. that’s just killed me 😂

"surely he didn't just put a piston over the barrel of an AR right" "Oh. Oh no."

>"dont try this at home" >goes to friends house

You essentially made a semi automatic jackhammer gun with attachments. Absolutely lovely

The ATF must love you lmao That was wild. For real though, that could honestly be marketed as a pretty good demolition tool.

"It worked but it broke" Then it's a true one punch gun

"Lets hammer some screws" Screws: "aight I'm out"

the fact you got it to cycle and it was properly gassed for 4 oclock ejection pattern was QUITE impressive...

You know it's a good youtube video when you're constantly thinking things like "How is this legal?" and "How is this person not dead yet?"

I love how he casually says “Steve is going to try to split this log with the axe attachment” like ahh of course the axe attachment!

“Is there a chance that I might’ve done it wrong? Absolutely not.” I wish I had this man’s confidence.

Kevin makes a punching gun, Allen makes a gunning punch

i am not the only one that thinks the military can use this for breaching doors or breaking tank wheels

Alternative title: The Backyard Scientist Goes Mad And Becomes Micheal Reeves

“I’ve made a piercing attachment” That’s just a bad jackhammer

this on a HCAR 308 would be the most powerful door removal tool ever. awesome video. wish youd go back to this stuff.

I think this is officially the threshold of this guy going from the “fun science side” to the “unhinged science side,” and I’m all for it.

Tonight: Florida man splits firewood with a semi-automatic axe, proceeds to smash locks and demolish his girlfriend's bathroom. More at 8 pm.

When you're going for a melee build but you wanna use a gun.

Smiles, sniffles twice, wipes tear away. It's beautiful

Wasn't expecting the extreme makeover part. Great video as always, the gun works like a wonder.

You're a madman. I love it.

"Let's hammer some screws." My smooth brain still feels something is wrong here.

I would add a cross over gas tube at the end of the piston stroke that bleeds gas from the high pressure side to the low pressure side. Then once the piston is all the way in the home position, have another port located where it all vents to atmosphere. Or at a minimum, drill a port at the end of the stroke to vent the high pressure side to atmosphere. There’s a ton of gas coming out of the breach. With the lack of pressure relief before the bolt opens, and the back pressure from trying to move something significantly heavier than a bullet, you’re going to break a locking lug on you bolt and/or breach.

“HECK NO WERE NOT GONNA USE A TINY LITTLE PISTON” got me laughing so hard

“Florida Man turns Gun into Melee Weapon”

"What [...] are you doing? ...you should get the grab bar!" She's a keeper for sure.

‘Builds a semi automatic punch gun’ ‘Let’s hammer some screws’ The duality of man

Man what a great watch! Very entertaining!

"We just need one more thing!" "gun." well alrighty then

Uh oh, no ads. Dangerous project, but definitely interesting.

honestly, i didn't "like" this video until i realized i was watching a plug for the sponsor, but was enjoying how well it fit with the rest of the video. Nice job

backyard is always so funny! 🤣 I almost died looking at the gun scene😂😂😂1:24

This is going to baffle the YT thought police.

I feel an essence of Michael Reeves in this video.

This truly is the most Florida of all the science KZfaq channels, I love you

8:52 So all I need to steal the bicycles I've always wanted real fast is a shotgun-looking actuated hammer with a cutting head? Dang, you really are a Florida Man.

I like how youve started channeling the inner florida man and become significantly more chaotic in this video

Bruh he’s letting off Michael Reeves energy in this video

You invented the best tactical entry tool ever. You should sell these to departments and rake in money. Love the channel.

I love how he's slowly becoming unhinged

Ah yes, a rare episode where Kevin has just gone insane with his power.

Bill Nye the science guy + Florida man + cocaine + KZfaq energy = The backyard scientist

ATF Sweating looking at how you just made a Semi-Auto Punch Machine

bro really reno'd his bathroom XD , plus when you went through the door handle with that thing i was so satisfied.

You literally just made a One Punch Man gun. I didnt know we needed this, but, alas we do. Nice work kevin!

The backyard scientist: “Bring out the assault fist” ATF: “The assault fist?”

This looks like something you could introduce to law enforcement for breaching doors

A fatter blank for higher flow would have been a good idea, like pistol calibers. I hope there's a 2.0.

"Don't try this at home" *proceeds to go to friends house*

No one is acknowledging, That this is basically a semi-auto jack hammer

"let's hammer some screws" had me dead

brilliant creation

He's slowly joining the ranks of Michael Reeves and William Osman

I feel bad for the ATF agent watching this man make a “suppressor” at home.

i cant believe i didnt found your channel earlier, you are truly the embodiment of a relatively SANE florida man, mixed iwth knowledge thirst and etnertainment. well compared to the news posts about florida man that is

that was the smoothest dissemble i have ever seen

Oh no, he has gone full Michael Reeves with the craziness level

"Let's hammer some screws." Wait a minute that ain't right

I thought he was just joking about the bathroom part lol I was so confused when he started destroying his own stuff 😭

With each new video uploaded, I am that much more astounded that he still has all of his limbs attached.

I feel like he's going down the path of becoming a family-friendly Micheal Reeves...

Me: *reads title* “of course he did”

Dude, this could be the most amazing portable handheld power hammer for blacksmithing. I'd love to try building this one day to test that idea out.

5:14 OMG that EXPRESSION when you said "Punching stuff" was AMAZING! LMAO

Relationship goals: “What the +#^>{ are you doing?” Ten seconds later: “Did you get the grab bar?”

We need to see this thing in full auto with the fist!

I saw your video when you first made it and I knew there was a device that was used like the punch gun that existed back in medieval times but I could not think of what it was and it has stressed me out ever since. Until today. The thing you reinvented is called a petard, which was an explosive munition in a bell-shaped cannon with a heavy object in front of it so that the explosion would launch the object to bust down gates. This is where the phrase "hoisted by my/your/his/her own petard" comes from.

"there's only one thing we need, GUN!" That should be a movie quote.

The police needs something like this instead of those battering Rams that never work

ATF: * frantically searching through laws I know it’s in here somewhere*

I love the one shot to open the door That can really save your ankle from kicking it

The Backyard Scientist “firearms” manufacturer

This is the most chaotic neutral thing I've ever seen.

11:12 And They were never seen again some say that they’re still locked in there to this day

love the tactical hose clamp vertical grips 🤣3:43

“In order to be a true power fister” -The Backyard Scientist 2021

My current level of manliness: "Let's hammer some screws!"

For the door stuck at the end, *looks at gun* "Modern problems require modern solutions"

This thing could unironically be useful

When you were shooting the brick on the ground over and over it made me realize that you just made a way less powerful jackhammer 😂

I try to channel your energy into my life every day

9:00 The Backyard Scientist actually doing yard work... with science!

"If you want to try something dangerous that might explode, try it on your friend's house." Thanks for the tip.

Sandra: Hey we should renovate the bathroom. Kevin: Ok: *assaults the door handle and commits battery against a can of Barbasol*

To be something so complicated as a piston gun to have less destructive power then a demolition hammer was quite of unexepected, but bricks and pc tests doesn't lie, but that contraption cool factor is one of the highest on earth, my compliments

Nice dude , I use them ram sets to put down steel track on the concrete for steel framing .

"I'm gonna try this at my friend's house" is a great thing to say when someone tells you not to try something at home...

The first thing I thought was that this would be a great door breaching weapon. Did not expect that my thoughts would become a reality in 10 minutes

This gun is hilarious, and I need one on the farm

can we take a moment to appreciate that Kevin made a AR-15 from direct blowback to a gas piston system more akin to an AK-47?

This man literally got different attachments like it was call of duty

I'm gonna assume the most expensive part of this build Was the ammo

him: misses with the fist atachment. some random kid who climbed over the fence to get their ball: gets skull oblliterated

"That was 5 shots for a break to brick" 🤣🤣

What would you do with a punching gun?
