This is actually some sort of Rubber material correct? not aluminum? I am curious…

This is a rubber material. Comes with one unit in the package. It made one of my uppers rock solid with no wiggle when attached to the lower. My other upper had a slight wiggle, but it still helped.

Cheapest Upgrade by Tyler Knapp, Verified Owner, April 3, 2025
