Mod weapons to reduce ap cost.

[Zawarudo]

So I just found about these modifications you can perform that will decrease the cost of action points per shot... and was wondering about tuning a shotgun like that :P

I mean... what if I could fire 10 times with a shot gun in vats? :D Damn that would be so nasty! Probably not possitle hehe... who knows?

This is what I found on redit:

"Overall weight doesn't effect AP cost. Just tried to attach bayonet on combat rifle (+ 1.7 weight or something like that) and the AP cost didn't change.

What does affect AP cost:

hip accuracy (every long barrel reduces hip accurary = more AP cost)
everything that says heavy/light (frame/barrel; heavy = more AP cost, light = less AP cost)

sights (scope = more AP cost, reflex = less AP cost)
fire rate (Hair trigger decreases AP cost - at least with pipe rifle)

recoil (better recoil - higher AP cost) stock type (short stock = less AP cost; on certain weapons like laser rifle and pipe pistol stock type actually change the weapon type - from one handed to two handed)

different caliber (.45 receiver for pipe rifle decreases AP cost) (different caliber doesn't change AP cost unelss it also change the fire rate)

What does not affect overall AP cost:

damage (powered, hardened and calibrated receiver for combat rifle has the same AP cost)

muzzle

weight"

Cool huh?

I like this site as it talks about reducing ap cost a decent amount:

The problem with using a shotgun like that is reloading in vats unless you use a combat shotgun and I prefer to use vats for medium distance as too long will mean a lot of misses and too short of a distance is usually not needed other then maybe for some bugs or ghouls that have rushed you and they only need 1-2 shots in most cases.

You also have this mod that can help a lot: https://www.nexusmods.com/fallout4/mods/4760

If you really want to know, download the Creation Kit and look at the game data...
AP cost is: fAttackActionPointCost
Each gun has a base value.
The parts have multipliers that are all added together, then multiply the base value.

For an example, 26 out of the possible 46 mods for assault rifles change the AP cost.
It can get anything from -55% to +105% AP cost.
Listing everything for every weapon would take way too long, so just better to look it up if you really want to know.

Not as hard as you might want to think.

I have a character that can get a full 16 attacks off with Overseer's Guardian as an automatic (48 rounds!). Now that's nasty
