To try and avoid this feedback being written off as a Mod Bug, I want to re-emphasize that **I believe this is a true Arma 3 Bug because the vanilla Arma 3 weapons do not correctly utilize the vanilla modelSpecialIsProxy feature, and the lack of proxy magazines carries the risk of reproducing this same visual bug for any Arma 3 vanilla weapons.** Based on documentation by community member Reyhard about magazinewells and proxies, the solution appears to be for BI developers to separate the already present magazine objects baked into existing vanilla weapon models into their own proxy model.
