The Waffle Magazine is a printable AR-15 magazine that has proven to be one of the top printable AR magazine designs released to date. It provides a bolt-together design that is easy to print and assemble and works reliably.
The design comes in several size variants - 13 rounds, 20 rounds, 30 rounds and 40 rounds. The latter two sizes also come in windowed and non-windowed designs. This magazine design also provides last round bolt hold open (LRBHO) functionality.
Each magazine can be built with nothing more than an AR-15 magazine spring and a few nuts and bolts available from any hardware store. This design thereby allows the fabrication of quality AR-15 magazines for only a few dollars in hardware and plastic.
