3D printed handguard with outbarrel printed inside of it

Ik ben Nederlands, maar voor de internationale interesse in Engels..

!!! this is a TOY for airsoft, not real firearms !!! All pictures contain legal airsoft replicas.

3D printed handguard with outbarrel printed inside of it. 
Weight is only 120 gram (for the 10.4 inch model, shorter ones are even less weight)

Comes with lightweight aluminium barrel nut and metal 14 mm CCW end thread (standard airsoft size)

Fits all m4 bodys

Sizes
*5 inch (fits perfect on MTW heretic labs)
*5 inch with longer handguard that fits tracer unit inside
*7 inch
*9 inch
*10.5 inch

Picatiny side rail and/or undergrip possible. You choose where you want them and then glue them into place (or I will do it for you)

Although this looks like M-LOK, it's not because the walls are thicker then the metal handguard. So I don't know if its compatible
