The Kuna Square Grip is a clever little piece of 3D-printed ingenuity that turns a simple takedown pin into a functional barricade stop and M-Lok rail. By matching the factory magwell contours and adding two M-Lok slots, the designer has given Kuna owners a low-profile way to brace against cover, mount lights or grips, and keep the gun’s lines clean. The v2 update with extra fillets shows the kind of iterative refinement that separates a quick print from a part that actually lasts under hard use.

For the 2A community this matters because it proves how quickly a niche platform can gain real-world utility once the files are out in the wild. Instead of waiting for an OEM accessory program, shooters can print, test, tweak, and share improvements in days rather than months. That speed democratizes innovation: a single hobbyist can solve a problem for an entire subset of owners who would otherwise be stuck with whatever the factory decided to ship.

Beyond the hardware itself, the Kuna Square Grip is another data point in the larger story of decentralized manufacturing. Every time a new file drops—especially one that integrates so cleanly with an existing receiver—we reinforce the principle that lawful gun owners can design, build, and improve their own equipment without asking permission. It’s small, it’s specific, and it’s exactly the kind of grassroots creativity that keeps the right to keep and bear arms a living, breathing technology rather than a museum piece.
