This wedge serves as a simple, effective solution for builders looking to reduce flex and improve the rigidity of the receiver interface. By filling the gap between the two main components, it helps maintain alignment and stability during operation. The natural rubber composition offers a balance of strength and shock absorption, protecting the receiver surfaces from wear while keeping the upper firmly seated.

Took the slop out of my old colt lower with my new Veriforce upper I bought, very happy! And they had the adapter for the front pin, but you have to call them to order one.
