UPDATE :

This one above has more content than this one I made, but I'll leave it as a legacy addon I guess.
At least the one I have got the crossbow and the accessories lol.

Welp, just some weapons from PUBG.

Be reminded that this is quite an old port actually, so it doesn't include all the new weapons that were added later on, and it might not look that good as well.

You can find the original SFM addons here:

And some accessories for the guns, althought they're not bonemergable, so you might have to put them up manually.
Or just use them as decorative models in your artworks.

Also apparently one of the accessories are having missing textures, it's the original addon's problem, so I can't really fix it, sorry about that.

And yes, I checked it, UMP9, Vector, and VSS Vintorez literally doesn't exist in original addon.
