M249 hop-up chamber
cults3d
Got fed up with the stock m249 chamber. Designed a new one that uses a lever system for better precision and propper r-hop adjustability All you need is a 1.5mm pin for the lever, two m3 set screws to secure the barrel inside the hop-up chamber and two m4 set screws to secure the chamber inside of the outer barrel. Depends on your printer quality, you may need to bore out the lever hole to 1.5mm As for dial stifness, adjust scale for optimal fit, as the design doesn't use a o-ring rather then utilizes a friction fit Update 6.9.2022: Changed some of the dimensions due to easier final assembly and elongated the alligment slots
