KRONOS Stock (Airsoft M4 Stock)

Inspired by the Hera CQR, KRONOS is compatible with ~⌀30mm buffer tubes. Created to house a custom programmable MOSFET circuit. All files should be made from PLA, PETG, or other rigid and durable materials with the exception of the file 'Buttstock', which is meant to be printed in a deformable material such as TPU. The file 'Strap Latch' should be printed twice for each side of the stock. Assembly requires #8-32 hardware, M3 hardware, and M3 heated inserts. IMAGES AND INSTRUCTIONS COMING SOON The internals are powered by an Arduino NANO and IRFz44N Power MOSFETs. The electronics enclosure is placed directly under the buffer tube and is a 35x80x40mm enclosure. The wires should run from the inside of the buffer tube to the stock. In my case, the battery fits snugly next to the wires inside the buffer tube and can be quickly swapped by unscrewing the buttstock, but if your battery does not fit there is a x__x cavity in 'Stock Housing'. Some guns may require modification for this; since my gun was originally front-wired a dremel was required to drill through the body and buffer tube to reroute the wiring.
