Tired of the stock drum mag on your saw and want to use something more standard but can't? Check out this awesome adapter. This is the ONLY off the shelf upgrade which bypasses the stock M249 drum which can't even feed at 25 rounds per second. This adapter is plug and play and will allow your M249 to feed beautifully at 25 RPS. Can't get this adapter anywhere else. Works great on A&K and featherweight SAWs. Feeds flawlessly full auto. Made out of carbon fiber ABS. Includes: M249 Adapter & Slide on lid Loading funnel (random color) DOES NOT INCLUDE THE DRUM ITSELF. ♦️IMPORTANT♦️: You are only buying adapter to fit on the drum and the funnel. Not the drum or the gun. If you are interested in anything else 3d printed send me a message. I think I am the only person on Hopup offering carbon fiber polycarbonate 3d prints.
