This is a Nailgun Mod, which corrects the position of the Nails + Lavanails for Nailguns and Supernailguns.
Originally, the Nails appear on the lower edge of the screen instead "out of the mouth" of the Nailguns.

This Mod corrects it.
(see screenshots)

Even, when you look straight in the sky, the nails still appear in the corect position now (for NGs and SNGs).

Special Thanks goes out to Sajt.
He told me what to do.
I simply followed his words and want to share it with you.

Greetings,
Seven
