Add installable gunmods to provide slots for other gunmods

[Rail-Runner]

Summary

SUMMARY: Content "Add installable gunmods to provide slots for other gunmods"

Purpose of change

Provides an inbetween variant between being able to easily attach a gunmod to a gun if a slot is available (doesn't make sense for many old guns) and not being able to do so at all, even with possible modification, that variant being "gunmod is installable with some permanent gun modification".

Describe the solution

Adds five different gunmods (one for each slot: sights, rail, underbarrel, grip, stock) and adds gunmod slots to most guns, on which they could be installed. Also adds recipes for those new gunmods.

Describe alternatives you've considered

Implement some sort of additional parameter on a gunmod slot to make it require tools to use the slot, but this seems a bit too complex.
Add just one gunmod instead, to "unlock" all of those slots, but some slots wouldn't make sense for some guns.

Jennings J-22: sights mount, underbarrel mount, rail mount, stock mount

Mon dieu, I don't think the world is ready for this monstrosity, even post cataclysm.

Some of these combos I'm not so sure about- there's a lot of difference between adding a bipod stud/rail section and having the appropriate furniture or real estate to install an m203 or a masterkey. In other cases there are questions I have about there being enough material to support such a mod- like a sight rail (I'm guessing it'd be a on-the-side style one rather than direct on the slide) on tiny little backup pistols to hold a full on high-magnification optic.

Fuji had mentioned that there was extant code for sawing down gun barrels via a gunsmithing kit- I kinda of think that would be a better implementation, necessitating the kit to actually installing the mounts so this level of 'mount abstraction' is justifiable.

I'm having a hard time imagining this with an underbarrel slot for a grenade launcher.

Honestly I'm curious.

I'm having a hard time imagining this with an underbarrel slot for a grenade launcher.

mod targets would still apply, many of the larger underbarrel mods don't apply to the small pistols.

That said, I feel like a lot of these necessitate volume increases, where others don't. A pistol sight rail might significantly increase the volume of the gun (mini red dot sight mill, drill and tap on pistols vs those large sight rails like these https://images-na.ssl-images-amazon.com/images/I/51GWyyn8DlL._SX569_.jpg that are kind of the only viable thing for pocket pistols), whereas a small section of pic rail on something like a flintlock is negligible.

Installed gunmods currently do add some volume if installed (I've set it to 8 ml per each, noticable for pocket pistols but negligible for larger guns). May increase it if it isn't enough.

I always imagined pneumatic bolt driver and pneumatic rifle to look like 'Helsing' pneumatic speargun and 'Tihar' air rifle from Metro 2033. So installing underbarrel mods is quite impossible for me, especially on the bolt driver.

They are inspired by that - if you look at the id for the bolt driver, it's helsing, and the assault rifle, tihar.

That doesn't mean they need to keep the same design though.

Seems like it'd work just fine if the air pump lever was not directly under the barrel, but instead a bit to the side. I think this can be taken into account while crafting the weapon, if desired.

While we are at this, could you remove stock slot from RM11B scout rifle? Its described as bullpup, and it is indeed very small for a sniper rifle with silencer and scope. Adding folding stock to this makes it crazy small.
And on second thought.... If we remove stock slot from this, will it be possible to give it back by using theese new tools? And to other bullpups?
And what about leadworks guns?

[tenmillimaster]

@railrunner 8mL seems ok for some, but not for sight rails on a lot of recoil operated pistols, which are quite bulky, or for any rifle platform that needs a side rail type attachment for optics. (Ak's, mosins, garands ).

I'm also certain that sighting rails will have significant volume on other launcher style or other heavy weapons. The RPG 7 and M202 themselves are examples of such 'protusion' style sighting arrangements. The M134 is another example, though volume on mounted guns is kind of a 'least concern'.

I think dropping a lot of the mounting points on the small guns (sights, rail, brass catcher), or using mod targets to specify by class is the best solution. Have a rail for pistols, a rail for launchers, and another rail for everything else.

Also why the change of parent of the Mossberg brownie? It's pocket pistol sized.

[Greevv]

I like the goal here, but I'm with Tonk. Possibly make those pistols require a "bracket" or sight rail mod before they can mount sights?

[Rail-Runner]

While we are at this, could you remove stock slot from RM11B scout rifle?

Done, no stock gunmod slot for it now.

And on second thought.... If we remove stock slot from this, will it be possible to give it back by using theese new tools? And to other bullpups?

Can't think of a reasonable way to do this. Well, actually something like a recoil pad might be doable, it just needs to have BULLPUP flag or something, and stock mods that are compatible need to have BULLPUP_COMPATIBLE flag or something. Maybe I'll work on this later.

And what about leadworks guns?

Made them moddable via permanent modification too. Couldn't think of a reason why it wouldn't work.

Possibly make those pistols require a "bracket" or sight rail mod before they can mount sights?

Done. Pistols and launchers now need alternative gunmods that are larger.

Also why the change of parent of the Mossberg brownie? It's pocket pistol sized.

Seems like it had a muzzle slot before (which it shouldn't have because it's multi-barrel), so I removed it. After this change nothing was actually inherited from pocket pistol entry as well, so I changed it to more general one too.

Also, slingshots and brace slingshots can now be modified to mount ergonomic grips and underbarrel laser sights.

Jenkins rebuild.

[kevingranade]

Need to re-audit this for some of the particular combinations, was this still allowing rail mounts on essentially derringers?
