The newest addition to the Parabolic lineup is the highly anticipated Nautilus back and tip combo for Planet Eclipse S63/PWR sets.

This set includes 1 detail oriented (and very grippy) milled back and one matching window cut tip. Both pieces are interchangeable with either planet eclipse back or tip.
(Insert shown to emphasize window milling not included.)

If you are looking to have a set anodized to match your marker, raw are also available.
