Unlike weapon packs that simply add reskinned pipe guns, MF 2.6.9 aims to replace the vanilla ballistic system with real-world weapon behavior. —for both you and your enemies.
Use with a damage balancing mod (e.g., Better Locational Damage or Wasteland Ballistics ) or at least set global damage multiplier to 0.5x via the holotape. Also install the MF Legendary Patch and avoid the “Tactical Ammo” option unless you enjoy inventory management hell. Fallout 4 Modern Firearms 2.6.9
