We design firearms that you can print at home. The AR-15 is the primary focus, though we do lots of other things. You can see some of them below.
Current designs include AR-15, AR-9, and LR-308 lower receivers, as well as stocks and grips. All of our designs can be printed on basic printers from PLA+.
To get started head over to the downloads page and grab your files. Pick up a printer and some filament. Read up on guns and 3D printing as much as you can. Check out our information pages. you can even get some parts from us. And remember, always read the README!
You can find Hoffman Tactical on YouTube, Instagram, Twitter, Rumble, and Odysee. To stay up to date, be sure to subscribe to the email list at the bottom of the page!
New stock system is ergonomically correct and has a positive retention method.
Taulman Glass Fiber Nylon Test Samples. Impact and tensile. Other then it's creep issue, I really like this Nylon.
AR-9 Prototype with built in support.
A separated 9 MM case. This is the result of a too light buffer in an AR-9.
Creep test with Overture Easy Nylon. Annealing almost completely eliminated the creep problem.
Buffer Bands fresh from the plating shop.
An LR-308 Prototype. I did not like the VO3D PLA that it was printed from.
Double Rib Lower after a range day. Taulman Glass Fiber Nylon.
Overture Easy Nylon waiting to be creep tested.
PLA test samples used to evaluate the new impact tester.
Test piece for testing different design parameters.
An attempt at more accurate printer calibration.
COEX Nylon. I have actually had a lot of clogging issue with the carbon fiber. I think it has too high of a fiber content.
TPU butt pad prototype for Gen 3 Stocks.
Playing with tree support. I still think built in support is much better, and will design some for a Glock frame sooner then later.
COEX CF Nylon. You can see the results of a nozzle clog on the right.
Printing a TPU butt pad for a Gen 2 Stock.
Old style Gen 1 AR-15 swivel pin plates.
Grip Prototype. I have found that an inverted honeycomb is a better texture then plain honeycomb.
3D printed AR-15 Upper and Lower prototype.
Chilling in the snow with the Double Rib Super Lower.
I bought this nozzle to use with fiber filled Nylon. The larger 0.5 MM orifice should help prevent clogging, but still provide good detail.
5.56 x 45 spent casings after a day at the range.
Triggers waiting to be packed into kits.
Nozzle Temp vs. Layer adhesion eSun PLA+
AR-9 Heavy Buffer. These are a must for a good AR-9 build.
My Ender 3. It's a capable little machine that comes at a ridiculously low cost.
A collection of 3D printed AR lowers. LR-308, Double Rib, AR-15, and AR-9.
Brass Bushings for the Reinforcement Kits.
V2.5 LR-308 Lower. This is a great lower, the V3.0 grip is nice as well.
Assembled V2.5 LR-308 Super Lower waiting for it's upper to be built up. KAK bolt and Aero Precision upper and handguard.
Annealing small glass filled Nylon parts in an oil bath.
V1.4 LR-308 Super Lower with the Gen one stock and grip.
3D Printed AR-15 and LR-308 lowers with the Gen 1 Stocks.
Square nut insert shortly before being imbedded in the print.
V3 Chairmanwon G17 frame. Pretty cool.
Lots of broken samples. Tensile and impact testing.
Fun under white phosphor.
This is an awesome lower. Push Plastic Carbon Fiber Nylon.
New buffer band prototype.
Cleaning the Prusa V6 Hot End.
AR-9 Super Lower with a KAK bolt and barrel.
308 Ammo with the V1.4 LR-308 Lower in the background.
The first functional AR-15 Lower printed by Hoffman Tactical.
I've had a lot of issues printing with the Push Plastic Carbon Fiber Nylon recently, but it makes for great prints when it works.
An interesting experiment. AR-15 Super Lower printed on a resin printer from eSun Hard Tough resin.
The first lower printed with a buffer band.
