Introduction: KLS V2 P90 Mod
I built the KLS V2 but didn't like the looks, so I put it in the body of everyone's favourite horizontal magazine weapon. It's nice and comfy, a realistic size, and fun to play around with, especially with the semi auto nature and quick reloads, facilitated by a redesigned mag release.
And no, I won't be posting this. If you want it so much, build a KLS V2, turn it upside down, and add bits until it looks like this.
