This mod is no longer being worked on, and will not be updated in the foreseeable future.
That being said, if you wish to use the files in any manner in your mod, please feel free to do so.   

This started out as a few added conversion receivers.  In the process, I went a bit overboard and wound up adding a much wider variety of weapon modifications. Some of the vanilla weapons and mods had their base stats modified in order to maintain balance between weapons. Each caliber change has multiple variants, mainly Rapid Fire, Armor Piercing, Automatic, and combinations thereof. I avoided adding mods that added straight damage changes, given that balancing them out would be a mess. The end result is a much wider variety of uses for each gun.


10mm Pistol:

• Name changed to N99 Pistol
• Base damage slightly increased (about a 10% boost)
• 8 .38 Receivers added

.44 Pistol

• Renamed to Pre-War Revolver
• .38 Receiver added
• .45 Receiver added

Hunting Rifle:

• Also, the .50 cal receiver gives a larger boost. Because .50
• Armor Piercing .50 receiver added
• 3 .38 Receivers added

Optional Plugins:

Maximum Compatibility Version:
Does not include changes to weapon damages or capacity. Does not require main file.

Weapon Balance Overhaul Compatable:
Avoids conflict with Weapon Balance Overhaul by Iron Rose. Requires WBO. Does not require main file. 

Shotguns For Shuenga:
Optional standalone containing only the Pipegun Shotgun receivers. Does not require main file.

Combat Rifle Plus Compatable:
Avoids conflict with Combat Rifle Plus by McShooterz (or any other Combat Rifle mod) by removing changes to the Combat Rifle. Works as a standalone, but I recommend using CRP so that the Combat Rifle gets some new mods. Does not require main file.

Compatibility with other mods:

• This will not overwrite other weapon mods added though other mods. Any duplicate mods will show. If you want to avoid this, open the files in FO4Edit, and delete the weapon modification and crafting recipe you like less.
• The same can be done with mods that edit weapon stats. Or just get the Maximum Compatibility version  
  

Mods that work well with this one:

• Realistic Survival Damage. Makes combat on survival and Legendary very kill or be killed.  
• Weapon Balance Overhaul. Tweaks weapon stats to make them more effective throughout the game.
• Extended Weapon Mods. Adds more weapon mods for an even wider variety of toys.  
• In L.I.E.U. (Leveled Items Extensive Unleveler). Unlevels all equipment items. Nicely compliments some of the lower caliber mods added, and makes combat a bit more interesting.
  

Still to be done:

• DLC weapons when they come out.
  

Changelog:

2.69:

• Removed Injectable Receivers due to them being mostly useless. Will add them once they have an effect more than 10% of the time.
  

2.65:

• Fixed duplicate of the .308 Armor Piercing Rapid Automatic Receiver on the Assault Rifle
• Fixed duplicate of the .38 Automatic Receiver on the Deliverer
  

2.6:

• Added Night Vision and Recon Scopes to Double Barrel Shotgun
• Changed model of the Pre-War Revolver Reflex sight
• Added Night Vision Scope to Pre War Revolver
• Added Reflex Sight to Deliverer
• Added Night Vision scope to N99
  

2.5:

• Added chokes to both shotguns. Combined with long barrels or slugs, shotguns can get quite a bit of reach
• Added fannable Slip-Fire receivers to the Pre-War revolver. I don't know why Bethesda didn't finish making those, they are fun as hell.
• Added short scopes to the N99 and Double Barrel Shotgun.
  

2.3:

• Fixed the assault rifle .308 AP receivers listing as identical to the default .308 
  

2.25:

• Fixed pipe revolver mods having messed up recipe lists and items. 
  

2.2:

• Added variants of most added mods and further refined the existing ones. All in all it added 62 more mods.
• Added a few unique effects from legendary mods. I'm keeping them tame until the GECK comes out, then I can add new models to make some of the more advanced effects make sense. 
  

2.1:

• Reduced Damage on Hunting rifle .38 receiver. Increasing the base damage set it out of whack, making it outclass everything by far. It's back to it's vanilla damage now, which is how the other .38s are based. (It's worth mentioning that pretty much every .308 hits significantly harder to make room for making 5.56 stronger to differentiate it from .45. The vanilla caliber damages aren't very consistent)
• Increased base damage of the Assault Rifle and reduced the damage dealt by the 5.56 Combat rifle. The 5.56 CR does about the same damage as the AR with a Hardened Receiver, ant the cost of reduced capacity.
• Added Shotshell Receiver to the Pre-War Revolver
• Added Mini-Nuke Canister to The Broadsider based off of the cut nuke projectile. Unfortunately, the projectile itself was too large to use (it's a fucking log) so a Mini-Nuke had to suffice.  
• Added a Slug Barrel to the Double Barrel Shotgun
  

2.0:

• Name changed
• Increased damage of 5.56 and .308 barrels (.308 was especially wimpy) 
• Reduced perk requirements for stocks on the Combat Rifle, Combat Shotgun, Assault Rifle, Double Barreled Shotgun, and Gauss Rifle.  
• Increased damage and capacity of the .44 N99 Receiver. It is now a good alternative to the revolver
• Increased firing speed of the .38 and .45 Pre-War Revolver Receivers, They now fire considerably faster, making them more worthwhile
• Increased the firing speed of the 5mm Automatic Assault Rifle Receiver. It now feels like a buzzsaw.
• Slowed down the firing rate of both the .50 and .50 Automatic Assault Rifle receivers. The semi auto is meant to feel a bit like a semi-auto anti-materiel rifle, and the Automatic is meant to feel like a heavy machine gun  
  

1.4:

• Corrected missing misc items for 5mm Automatice Assault Rifl and .38 and .38 Auto Deliverer Receivers. Whoops.
• Added Injectable (Syringer) Receivers to the Revolver and Hunting Rifle. 
  

1.3

• Reverted the Deliverer to 10mm, added .38 and .38 Auto Receivers
• Added Shotgun receivers to Pipe Revolver and Pipe Bolt-Action
• Added .308 Minigun Barrels
• Added 5mm Automatic receiver to Assault Rifle
  

1.2: 

• Added .38 Automatic Receiver to N99 
• Added .308 and .50 Automatic Receivers to Assault Rifle
• Added  .38 and 5.56 Automatic Receivers to Combat Rifle
• Added 5.56 Minigun Barrel
  

1.1, A.K.A This Fucking Combat Rifle Though:

• Returned .308 receiver to Combat Rifle. Since 5.56 had identical stats to the vanilla .308, it's damage was boosted at the cost of a slightly slower rate of fire. 
• Fixed the 5.56 receiver for the Combat Rifle. Ironically, it still fired .308.  
• Reduced Gun Nut requirement for .38 Combat Rifle receiver to rank 3
