Now that I’ve got your attention with the “free” thing… 
This 3D printed M16 Grenadier handguard came into my possesion thanks to BigMuthaDrum’s cleanout. I have no use for it.
Rougher than an old hooker’s head on a Sunday morning and no doubt printed in PLA, it needs a lot of filling, sanding, screw hole redrilling and cleaning up to bring it up to speed.
Nonetheless it’s free to anyone who wants it and can put it to good use on a build.
Hit me up, let me know and we’ll see what we can do. It’s just taking up space in a storage box as it is.
