BT Site Rail - Fixed

Built with a strong, lightweight plastic stick and wrapped with a soft, non-pilling fleece swab. Two per package: one straight stick for staging areas and one bendable barrel swab to take on the field. They soak up the paint and are built to last.

This adjustable site rail looks like tha actual M16 site rail.

With this replacement kit, you can keep your springs nice and healthy. This kit contains springs of varying tensions for a variety of velocities.
