Airsoft M4 Drum Mag feed tube repair/upgrade (battleaxe)

thingiverse

Ordered a cheap drum mag from taiwangun for my airsoft m4, however you get what you pay for and it has a major design flaw resulting in it failing nearly immediately. This part is to replace the small plastic connector that goes between the motor assembly and the feeding tube/spring. The original issue is that the spring bends round to a near 90 degree which puts a lot off sideways pressure on the connector, and as it's cheap weak plastic it just cracks and then snaps away. Using a curved piece instead takes this pressure away almost entirely. The piece is sized so it pretty much makes contact with the walls internally so should be stable and secure. If you find the internal hole is slightly too small, just run a soldering iron quickly around the inside of the ends until the spring/motor assembly sit snugly.
