Swordfish Handguard for AR

So i saw some bunch of swordfish handguard that was designed for SMG and other weapon category and i wanted one for AR styled rifle. There is one available for sale but since it is much more cheaper to just 3D print it, so I remixed the one from MP5. It kind of works as rail riser since the rails are elevated but im happy with the design for now, hopefully the design will fit with other AR rifles so that people can use it without heavy modifications.
