A maker has published an original folding stock for bufferless platforms that carry a rear Picatinny rail. The design includes a TPU-printable buttpad and cheek rest, with the rest adjustable across four positions. It is built to work with an MCXish hinge; a remixed hinge file ships with the release and is also offered separately.

The designer produced the stock after finding other braces too flexible under shoulder pressure. The files are labeled an open beta, and users are asked to note any problems in the comments.
