Gonna start off by saying that I'm no expert when it comes to firearms, but I do know that a rifle being automatic doesn't cut the range in half. I mean, come on Bethesda.

Features:
-Lowered Weapon weights to be more reasonable (a combat rifle shouldn't be 20lbs)
-Disabled Dismemberment for weapons where it didn't make sense (almost all of them)
-Rechambered Combat Rifle to 5mm (an infantry rifle chambered in .45 makes no sense. Plus it gives 5mm a purpose)
-Rechambered Pipe guns to 10mm (.38spc is a revolver cartridge)
-Rechambered Pipe Revolver to .38 (.45ACP is a pistol cartridge)
-Muzzle devices no longer adversely affect range
-Automatic receivers no longer adversely affect range
-Greatly increased range of most weapons, but they have more recoil to balance this
-Changed Combat Rifle compensator to Assault Rifle compensator (Just my personal preference)
