Airsoft M249 Box Magazine using hi cap mag internals

thingiverse

This is the internals for an airsoft M249 box mag. It uses a M4 hicap mag on the inside with a motor to drive the mag. I made this to feed into a Stoner 96 LMG. I believe a different mechanism is needed for an M249. Example of this magazine internals working in a M249 box. https://img.youtube.com/vi/i6_qxhazE9Y/0.jpg Parts list: * 3 - M3 x 10mm bolts * 2 - M4 x 30mm bolts * Hicap Magazine https://amazon.com/gp/product/B072BB8YYR/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 * DC Motor: https://www.amazon.com/gp/product/B07DDC3ZBK/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 * Feeding tube: https://evike.com/products/59003/ * Magazine body: https://venturesurplus.com/products/used-army-m249-200-round-saw-ammo-box/ I am working on a version of this that will not require the hicap mag. It will use an all 3D printed mechanism to load the bbs. This will be cheaper and this should decrease the size of the internal structure allowing for more bb capacity, potentially making this a > 5,000 capacity.
