Breaks sniper rifles in first person, mod author too proud to make an uninstaller or even telling us which files were modified, probably because they're a plagiarist who have no idea what they're doing. Awful work.

Since people seem interested I compared both weapons.meta files to find the differences: The modder just change "LaunchSpeed value" on a bunch of stuff, but it was missing some lines that are present in the original game:
<Item>
<Name>COMPONENT_MICROSMG_VARMOD_FRN</Name>
<Default value="false" />
</Item>

<Item>
<Name>COMPONENT_CARBINERIFLE_VARMOD_MICH</Name>
<Default value="false" />
</Item>

<Item>
<AttachBone>gun_root</AttachBone>
<Components>
<Item>
<Name>COMPONENT_RPG_VARMOD_TVR</Name>
<Default value="false" />
</Item>
</Components>
</Item>

Pitiful install instructions from both Author and moderator. To install, you'll need openiv, copy x64e.rpf (Optional) and open it with openiv, place the files in x64e.rpf/levels/gta5/vehicles.rpf

"– How can I sell my Property? No."
Well this is a pretty awful FAQ response, especially considering that properties don't respect which save file you're using. If you want the real answer you can't sell properties, but you can open "SPAII Setting.exe" go to Properties, go to the property you don't want anymore and change the owner to "Nobody"

Is there any way to get the Dynasty 8 site working? It will help me decide which properties I want to enable or disable, and I can't find a more convenient map anywhere online. The mod as is relies on you already knowing which properties you want (Memorizing all of them) or driving to each location and checking it out or looking up each individual property to see if it's worth getting or not (Time wasting)
