M249 but Russian

About this mod Author’s original text

Modul PU-21 Lightmachine Gun

The Russian experimental LMG that is meant to work like the M249? Failed obviously but it definitely was a cool thing in the Russian arsenal back in the old days. The Soviets realized that it was redundant and unnecessary and didn't pursue further with the programme.

This mod features a whole slew of stuff that was COD-ified but certain was a thing still.

Barrels, handguard, grips and stocks can be changed. Furthermore, chamberings as well. Though due to how multi-chambering works for belt boxes, they are changed similarly to my other HK LMG mods, where you have to empty the belt mag and then change it via touchpad button to switch chamberings, which includes, 7.62x39mm, 5.45x39mm, 5.56x45mm and 9x39mm.

Handguards have hidden picatinny rail, and there is a hidden rail at the top of the cover.

In order to use the magazine part of the gun, press on the cover to pop it open to be able to load your mags in!

Features

  • PU-21 in modular format!
  • Barrels, handguards, stocks, grips are all interchangable.
  • Stocks even include a picatinny stock option because why not
  • Grips are also changable via ModulAK as well, though they might not always fit!

Model from Call of Duty Black Ops 6; With massive thanks to Oxy for the support!

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
