This Resource pack includes 3 Edited models for Guns from MrCrayfish Gun Mod
Assault Rifle - Based off AR15

Pistol - Made the Slide slightly bigger, moved the Grip a bit forward, and added Iron Sights

Shotgun - I tried to make it fit between current one and a Pump Shotgun from NineZero's Gun Expansion mod. (Model might be changed later)

FAQ
Q: Will you port it to versions below 1.16.5?
A: No.

A: No, Current 1.20.1 version is not official, however, when the official 1.20.1 version or higher comes out, I will look into it.
Q: Will you port it to Bedrock? (aka Android, Switch, Xbox, etc)
A: No.
Q: Hey I saw your resource pack on another website, did you upload it there yourself?
A: No. I did not upload my resource packs anywhere other than Curseforge, if you downloaded it elsewhere, there's a chance that it might contain malware.
