M1887 (Almost) Leak free fiil nozzel

thingiverse

One of the biggest problems faced by owners of the S&T M1887 is the extremely leaky fill port, which makes it barely possible to manage 10 shots per fill. Designed to solve this issue, these nozzle adapters feature a flared head that fills the space where gas leaks occur, making an o-ring unnecessary and saving time and effort in the process. The nozzles are relatively simple to print, but require extra time due to their precise nature.
