How 3D Printing is Revolutionizing Firearm Design (ft. Angstdat Arms)
Description
Rich Angstadt, president and founder of Angstadt Arms, joins State of the Second hosts John and Kaylee to trace how a personal want became a company built on innovation. Angstadt's grandfather got him into firearms young, and his family history runs back to the 1700s and 1800s, when the Angstadts were master gunsmiths crafting Kentucky long rifles and smooth bore muskets. Around 2011, after exiting a previous company, Rich had free time, was shooting IDPA and IPSC competitions, and wanted a 9mm AR built around a Glock pistol magazine while keeping all the AR15 controls. He took the design to SHOT Show in 2015, picked up big distributors and dealers, and helped shape what became the pistol caliber carbine market. The first gun was the UDP-9, a straight blowback AR9 on Glock magazines.
The conversation moves through the company's product arc and what drives Angstadt to keep building. Selection by the US Army for its subcompact weapon trials forced a sub-15-inch length requirement that pushed development of a modified cycle system with Deadfoot Arms. Angstadt didn't win that contract (B&T did), but the work gave birth to the MDP, a roller delayed AR9 that runs on Glock magazines, weighs three and a half pounds, and shoots flat and low-recoil like an MP5. Rich explains why the company chases innovation over the industry's me-too habit, and how metal 3D printing (laser sintering titanium, not polymer) gives speed to market. A new design can be printed, heat treated, and test fired in under a week, which lets the team try ideas that a full manufacturing line would never justify. Testing remains the part that can't be rushed, and contracts often dictate the accuracy and reliability standards.
The second half turns to suppressors and the NFA. Suppressor sales have surged on faster approval times, dropping from up to 12 months to as little as a day, and the $200 tax stamp goes to zero on January 1, 2026. Rich predicts deeper integration between firearm and suppressor, more integrally suppressed designs, and suppressors becoming a normalized product gun owners buy in multiples. He's bullish the NFA's days are numbered but less certain short barrel rifles will take off the way suppressors have, given how well pistol braces already serve that role. Kaylee details GOA's lawsuit to gut the NFA, explaining that the zero-dollar tax stamp creates the legal grounds to sue because the Supreme Court previously held the NFA could stand only because it was regulated under a tax. The group discusses normalizing gun culture, getting first-time owners into the fold, range rental programs, and starting new shooters on suppressed .22 so they never develop a flinch. Rich closes by pointing listeners to Angstadt Arms and asking them to support their local gun stores.
Questions this episode answers
How did Angstadt Arms get started, and what was the first gun the company built?
Rich Angstadt founded Angstadt Arms around 2011 after exiting a previous company, wanting a 9mm AR built on a Glock pistol magazine while keeping the AR15 controls. He brought it to SHOT Show in 2015, and the first gun was the UDP-9, a straight blowback AR9 that runs on Glock magazines.
What is the difference between Angstadt's straight blowback and roller delayed AR9s?
The original UDP-9 is a straight blowback AR9 on Glock magazines. The MDP is a roller delayed AR9 that also runs on Glock magazines, weighs three and a half pounds, and shoots flat and low-recoil like an MP5.
How does metal 3D printing change firearm prototyping and speed to market?
Angstadt Arms uses metal 3D printing by laser sintering titanium, not polymer, so a new design can be printed, heat treated, and test fired in under a week. That speed lets the team try ideas a full manufacturing line would never justify, though physical testing still can't be rushed.
