The ARK 2.0 Build Kit represents a new generation of modular, DIY firearm-building platforms, specifically engineer for rifle-caliber performance while using primarily 3D-print components. Develope by the renown designer Invader Zip, the ARK 2.0 expands the creative possibilities of home gunsmithing, marrying modern additive manufacturing techniques with traditional AR-15 parts to deliver a functional, reliable, and highly customizable firearm.

Comprehensive Kit Contents

At its core, the ARK 2.0 Build Kit includes all the essential components require to assemble a working rifle platform, aside from the 3D-print parts that users produce themselves. The kit typically ships with a 16-inch AR barrel (featuring a 9 mm outside diameter and a .004″ barrel-nut shim), a complete bolt carrier group (BCG), charging handle with Riptide Rails, and a buffer tube assembly with spring and buffer weight. Additional elements include a gas block, 15-inch modular handguard rails, hardware sets, and heat-set inserts that reinforce key polymer joints. To support the build, a USB drive containing STL/CAD files for the printable components is also include, empowering users to fabricate the lower receiver, stock, and other key parts on consumer-grade FFF (fuse filament fabrication) 3D printers.

Design & Engineering

The ARK 2.0 was design around a tri-material structure: high-strength 3D-print polymers form the bulk of the firearm’s frame, reinforce with metal inserts and pair with AR-15-standard steel components in high-stress areas. This approach keeps the system lightweight while ensuring it can handle rifle-caliber pressures. Compatible chamberings include .223 Remington / 5.56 NATO, with experimental support for .300 BLK, 7.62×39, and 350 Legend.

Ease of Assembly

Aim at enthusiasts with intermediate DIY skills, the ARK 2.0 requires no specialize tools beyond what’s common in home workshops: Allen keys, armorer’s hammers, drills, and a reliable 3D printer capable of printing materials such as PLA+, PETG, or CF Nylon. Builders are free to experiment with color schemes, textures, and ergonomic modifications, thanks to the open-source design files.

Innovation & Versatility

Whereas earlier DIY firearm kits were largely limit to pistol calibers, the ARK 2.0 breaks new ground by offering a full rifle-caliber platform in a mostly 3D-print configuration. Its modularity allows for rapid swaps of barrels, handguards, and stocks, making it highly adaptable for various shooting applications—whether target practice, competitive shooting, or experimental builds. Users have report reliable performance exceeding 1,000 rounds with proper maintenance, a testament to its robust engineering.

Why the ARK 2.0 Stands Out

This kit embodies the ethos of the modern maker movement: accessibility, customization, and innovation. By combining widely available AR-15 parts with cutting-edge 3D printing, it lowers the barrier to entry for building a capable rifle, all while offering nearly limitless personalization options. The include design files encourage learning and creativity, allowing builders to iterate, modify, and even develop entirely new configurations.
