Read the whole post.

It's set up to use a couple of mods: Mercenary Plasma Pack , CBR Redux , Katana Pack (though it's kinda iffy, Resistance Firearms and Clean TLE weapons . Could be I missed some. For some weapon classes it uses weapons from these mods Additional Weapons Pack , Beowulf Rifle Pack , Primary Secondaries (haven't really tested it though and Long War SMG Pack.. All weapons assigned to autopistol category (MAC10 and Mini UZI IIRC) are modified to use values from this mod Autopistol Overhaul
You need to download all of these mods to have the pack fully functional.

Now the most important part. if you just want the weapons present as options, only copy the 707548632 folder. The rest are configs for CBR and Resistance Firearms to keep weapons in-line with the weapons from mods that add weapon classes (or in-line in general in the case of CBR) as the weapon copy function of XSskin doesn't seem to work. It also modifies Glock 18 and Skorpion heavily into a new sidearm class, which can be almost as good as a primary weapon, but most of the time it's on par with a pistol (or worse). It also has terrible range. For hiding weapons in avengers inventory I recommend WSR
