>>6619515Yeah, it's a little different in how the rails connect, but that's sorta how it comes out.
Basically, the grenade launcher takes the place of the lower receiver, so the pistol grip and trigger guard fit directly together.
Pic related, it's the grenade carbine next to a couple other of the weapons for scale. Maybe "carbine" is giving it too much credit. Grenade pistol is selling it too short, though. Grenade coach gun?
