Ah yes, the AR-10 rifle from the Metal Slug series.
So yeah, another SWEP I made, which is also based off one of the older model ports I made.

But I haven't figure out how to make underbarrel grenade launcher work in TFA, so it's unusable for now, pardon.

It's kinda funny how the original L4D2 addon actually used the model I ported back then, and now I'm porting it back to Gmod again as a SWEP, lol.

This SWEP was ported from L4D2 workshop with permission granted:
