Omg, "those are just side benefits ". Listening to makes me miss my father terribly. You both would've gotten along exquisitely.

It is a sleek looking clean design. This alone puts it ahead of nearly every factory carbine I've seen come out in the last 20 years. In some ways it reminds me of the HAC-7, only this rifle appears to work.

The best thing about the JLC-24: it’s not an AR15. Variety is the spice of life.

This is a badass build--kudos to the designer/builder. Thanks for the video!

Nice to see 3D printing being used to augment traditional techniques. Ancient and modern.

That rifle's shape is reminiscent of an LR-300

I started a tool and die maker apprenticeship just so I could learn all the different aspects of metal working and design that are needed to manufacture firearms. i'm coming up on my first year now and so far I've learned Solidworks, Catia, I'm currently learning Tebis while working with an okuma CNC mill, I've started learning how to properly operate a Bridgeport, how to tig weld(still pretty new to this and need a lot more practice to get good), how to properly use a drill press, how to use a stamping press, how to hand fit components with critical tolerances, how to use a surface grinder, etc. I think I chose the right path instead of doing a gunsmithing apprenticeship. That wouldn't have gotten me anywhere close to where I want to be. Ultimately I want to make rifles and pistols and own my own firearm factory.

What you describe as SMR is literally the replicator from late-era Star Trek, and I think some have - like myself - realised that all a replicator is, is a 3d printer that uses forcefields instead of a 3-axis grid and a print head, and a single-molecule nozzle.

@@flightlesschicken7769 right. The impression I was that it was operating at that subatomic level (I freely admit I oversimplified in my initial comment, I was trying not to go *full* trek-lore-nerd, heh.) - the part where the transporter comes in is in creating scan images of real food at a resolution that can be 'printed' - which is lower than full transporter res because you don't account for quantum. It would take far less energy to disassemble and reassemble stuff, even at the subatomic level, than to try and directly convert energy to matter. This is ignoring the in-universe plothole of how the transporter moves someone's matter from A->B

Thanks Mark! Love your commentary as usual.

What an amazing example of really Taking what you have on hand and just with a little creativity and expertise making something truly amazing With so little!

Seriously impressive with the methods he used!

Once again i've had to be subscribed to both of your channels today.

The term used in industry is called "Atomically Precise Manufacturing" - where items are built atom by atom, molecule by molecule.

Reminds me of an old colleague back in the early 90's, who made himself a new rather intricate kitchen interior with very ornate details during his free time. Only using hand tools and a hand router with hand made guides. Even though we had all the latest machines we used in the daily production. 😅

That is a masterpiece of creativity.

That is awesome! Great work and nice to see some alternative uses of firearm-related 3d printing.

Damn! I'm in love! First off, I've always known that you could use a router for more than doing an 80% receiver. Second, if you think those methods were crude they we nothin. I'm A blacksmith and I just finished my thirty two ACP with a forge and a file. Not to mention a rifler that's used for making muzzleloading rifle barrels. As the man said "where there's a will, there's a way. BTW, the reason I used 32 is its a lot easier to headspace in an semiautomatic pistol. I'm really happy to see our constitutional rights being upheld with cutting edge technology, because when our forefathers wrote the constitution they didn't know what our future technology would be, they just knew we would have it. Therefore they time and tech proofed it by using the most straightforward language possible. For that we must cheer them once again because with their forethought we are a free people. BTW, I hate politics right and left. If they could stop trying to get brownie points off their colleagues they'd see what was right before their faces and get some work done. This also goes for the idiots who stand and egg the bastards on for no other reason that I can see than to cause chaos.

Awesome job Justin 👍 Thanks for sharing Mark.

Actually looks great. Not only does it look great from an aesthetic standpoint, but it also looks good engineering wise. I remember learning VCAD 386 back in the day. Doubt any of that knowledge works with modern CAD programs, ha. The base of the technology you described exists. It is not viable beyond large companies doing R&D right now, but I have seen some awesome things, like fully enclosed gear sets that would be impossible to make in any traditional way. We are getting closer and closer to sci-fi style replicators every day.

Damn. Justin, this is siiiiick. Super sick. I see the hammer tig work. I see almost all the lil easter eggs in there. Nice piece.

Spot welded receiver. luv it

Sick piece! Great work, Justin!

Excellent work

That 3D printing lets you create a simple and effective jig to help you easily ECM rifle a nice piece of steel tube, turning it into a surprisingly good gunbarrel, this fact alone is so wild to me. I can only imagine where things are gonna go as additive manufacturing develops further and gets cheaper. One day, there'll be a machine which will be able to print out the individual parts for a weapon much like a MAC M10, springs, magazine components, and barrel and all, and all you'll need to do is assemble it and it's done. Perhaps the parts can even be surface finished as part of the printing.

Seems to work ok for a amateur build 😉👍. Greetings from the 🇬🇧.

Very ingenious. Hope he brings it to market

I think that design is a neat idea, but it should have an AR lower and pin attachment points for work with the popular market.

I can remember making an under-rib for a .45 acp target revolver I was building in the 1970s by drilling the barrel diameter (untapered bull barrel) in a block of steel and cutting away everything I didn't want with a shaper. It looked pretty good when I got it finished. Heck, I read about the Afghanis, before our little war with them, SMLE .303 out of CAR PARTS using blacksmithing level equipment. That rifle made me think of a commercial I heard about 10,000 times in my childhood. For Timex watches, they'd do things like strap them on an outboard motor prop and run it for a few minutes, then John Cameron Swayze would bring it into the camera view and you could see that, at least the one he was showing, was still running. Then he'd say, "It takes a licking and comes up ticking." That rifle was certainly ticking away.

Looks very good
