Version 1.1 updated on January 30, 2026:

Fixed abnormally high damage when using the True Damage mod. Fixed and added the correct keywords so that weapons gain bonuses from talents like Rifleman.

The vanilla shotgun was the weapon I used at low levels every time I beat the game, and completely forgot about it when the battle rifle became available, so this mod aims to change that.

illustrate

With its new modification options for the vanilla shotgun, the mod opens up a new mid-game endgame for the weapon that completely changes the nature of its bolt-action rifle. Now, at the third level of the Gunsmith perk, you can install the first semi-receiver and automatic receiver along with their new ammo conversion options. Additionally, there are upgraded receivers available and new barrel options for automatic fire due to more demanding perks like Rifleman or Heavy Gunner. The new receiver uses battle rifle animations, so any animation rework mods such as Wardaddy's Combat Shotgun and Rifle Rework Animation Pack (which I recommend) will work fine.

List of new features (currently):

4-column semi-automatic and 4-column automatic receivers with new custom meshes and textures,

New machine gun barrel options to suit your machine gun needs,

2 new iron sight options for new receivers with custom grids and textures and regrid stock options,

Five .308, three 7.62 and one 45-70 magazine modification options,
