Overview

The NC-20A Nose Cone Insert plays a critical role in the performance and reliability of your model rocket. Installed at the base of the nose cone, it functions as a retention pin that secures the cone in place during boost while allowing controlled separation at apogee.

Engineered from injection-molded ABS, the insert offers a durable yet slightly flexible structure that resists breakage under launch stresses. This design ensures the nose cone ejects cleanly without premature release or excessive friction.

Sized to fit BT-20 body tubes, the NC-20A Insert delivers precise engagement and alignment with the rocket’s shoulder. Modelers can lightly sand the insert or tube interior if adjustments are needed for an optimal fit.

Trusted in rockets like the Ripley, Trail-Blazer Trio, and AVG Bulk Pack, the NC-20A Nose Cone Insert provides consistent performance, making it a must-have replacement part for your fleet.
