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?

[@mkhd1355]

@pierrebrochant If it was 3D printed, yes.

Awesome Tim!! I've played with the previous one and love the addition of the last-round bolt hold open!

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.

[@AaronMT09]

Thank you sir for all that you do and continue to do! You've inspired me to get into 3d printing, went to my local microcenter today and purchased my first printer. They had the creality k1's for $429

[@4500MHz_Jay]

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

[@N0TZR1]

Immaculate work good sir. Marvelous work of craftsmanship and engineering once again. Hats off💯

[@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.

[@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.

[@winchester7mm]

Amazing work as always! Tip O the hat, mate!

[@deplorablesecuritydevices]

The hoff does it again! Great stuff, bringing the means of production and self defense back to the people.

[@chris993361]

I have been meaning to try some of your other builds. I love my Orca.

[@Catboy-hr2qp]

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 ;)

[@wtdconcepts]

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

[@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!

[@ypsiprepper]

Id love to see if Bambu Labs new PPS-CF would make a good material to print with. It is just expensive at 130 bucks for .75Kg.

[@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.

[@That_Guy5575]

This seems like a good candidate for a dedicated lower version for the Mat9 upper

[@tedo3332]

Boom!!! You're crushing it!!!

[@xinsertnamex]

Would love to see a super safety that’s compatible with the sl-9

[@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.

[@charlesg5085]

That pistol brace looks like a felony waiting to happen.

[@RichardCranium321]

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

[@HoffmanTactical]

It could be done, but would be more complex than mirroring the print. STEP and PART files are provided.

[@dans.98]

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

[@CowboybubPercussion]

That brace makes me very nervous because it lacks ant strap holes for the brace that the blade style of brace usually facilitates. That’s just me tho

[@JmanPerformance]

Will this work with CMMG's Radial Delayed Blowback bolt? And are you planning on making this lower that takes larger frame glock mags? (45 and 10mm size.)

[@aardwolfweb]

If you were going to machine aluminum plates, why would you do hex pockets? Why not just thread the plate?

That was a option I looked at. It's more costly, not streamlined, and the hex nut system is still required for all those who want to use printed plates.
