My Best AR-9 Lower Yet

[@thamomentum]

Aside from firearm related. As an engineer, I would shake your hand. Nothing short of beautiful engineering and bare bones R&D. Really impressive.

[@pierrebrochant]

Would you also shake the hand of the men who developed the first rocket-powered GPS-positioned bacteriological WMD vector, due to the fact it is such an engineering marvel?

[@hendo337]

I have one of those Stern Defense 9mm Glock Mag, AR15 magwell adaptors, I always thought it would be cool if there was a way you could make a 3D printer print tightly around it to eliminate the misalighnment issues, have a bolt hold open, omit the normal mag release, the lower would probably be pretty strong with that nice metal piece in the center, it might be a bit larger than necessary but it would certanly be a solid piece with all your strength upgrades in PLA+ or CF. I suppose this invention makes the Stern a bit redundant since you can afford to buy a lot of stuff instead of paying $229 for an adaptor. Almost enough to just get a 3D printer or buy a G19 parts kit and have a sidearm or get a basic upper.

[@bettycocker2226]

i like the way the spikes lowers work. very simple and easy to fix. this is kind of like that, except hidden inside and an extra part.

[@4500MHz_Jay]

That BHO lever design and replaceable ejector is ingenious. Good job Man

Amazing job! Both in the design and in the presentation. Thank you for all your hard work!

[@hendo337]

What if you took a strong apoxy like JB Weld and smeared it into that Z banding to make a smooth surface and it cured, would that create a strong hard surface that would hold up and remain withing specs? Just sort of a off the wall idea, it would be inside where its not visible. Theae are the sorts of things I often find myself doing when I work on older vehicles and I am "doing the wrong thing the right way" like repairing a gouged sealing surface on an intake manifold for a carb/throttle body, the surface for a thermostat housing, a gouged timing cover, blocking off some sort of emissions eguipment, like JBing a bolt into the EGR output on exhaust manifolds, plugging a vaccum port, blocking ports the a smog pump would feed after I delete it.

[@steveninaz9576]

Wow, i have several factory ar-9's, and your lrbho is a far better design. Great job, Sir.

Alot of people are using high speed printers, I think Hoffman needs to do a test so he can recommend print settings/filament recommendations that'll still provide good strength at those print speeds

[@HoffmanTactical]

I run everything slow. Fast printing is a gimmick in most cases.

[@BestBoricua]

​@HoffmanTactical brother, my lowers have over 1k rounds through them with high speed printing. Gimmick?

[@HoffmanTactical]

@@BestBoricua They are not as good as they could be. Slow prints have no downsides in most cases, the desire for speed when it is not needed is the gimmick ;)

[@rustythefoxcoon5143]

Hey I got a wild idea I’d like to see you or PSR try! I doubt you gonna read this, but I want to see if we can use nothing but a drill, sand paper, and a file in conjunction with a 3D printer to make a Glock 17 slide. So maybe get those file resistive rods other jigs use, and get a block of steel to try and mill the B to a G. You could also use cheap drill resistant inserts in the jig for make it accurate. It’d be a game changer making 3D printers no longer limited to plastic as they can be proven to make the tools needed to make metal parts!

[@ElohimYellow]

Nice upgrades.

[@dans.98]

Totally awesome stuff . Got to make one for myself .😮

[@jamesbaker3153]

[@johnwilliams727]

It would be cool to see an AR upper with the buffer tube integrated into it so as to solve the weak link of printed lowers.

[@HoffmanTactical]

It's not really a weak link anymore. But if you want that, the ARK 2.0 does so.

[@SKPhoto816]

[@diplexnormal3353]

I have to ask. Was your inspiration Philip A Luty? The only reason why I ask is Because your work reminds me so much of him but it’s impressively *so* much better. I have taken upon myself to do as Philip had done and continue to prove that firearms can never be seized or banned, to prove that gun control can never fix the one problem that voters seek to reduce *-by becoming the problem itself.*

[@chevrofreak]

Overture is my favorite filament manufacturer, and I have found that the Easy Nylon, once dried, prints beautifully in my Bambu P1S using their Bambu PA-CF profile. Are you going to try their new Super PLA+? I have a spool but I haven't printed with it yet.

[@HoffmanTactical]

Don't plan on it. The Easy Nylon does print great, but has very limited application.

is it possible to make one of these either with an ejector on the right side so cases eject left OR just completely mirror the print to be fully left handed? i came across an old A2 carry handle upper thats factory cut for left eject and it came with a 9" 9mm barrel & carbine length triangle handguard. someone was building a lefty retro 9 but im only aware of one company making ambi 9mm bolts and lowers with ejector fin on the right - 600 bucks for bolt n receiver. no way im paying that
