The Topstop acts as a heavy duty cap on your upper receiver that stops the bolt carrier group and charging handle from sliding out as the upper is moved around. 
Made from a super tough polymer, the Topstop snaps firmly into place and covers the entire bottom of the upper receiver, providing protection for the receiver lugs as well as the inside of the receiver itself.
This product is perfect for storing or transporting barreled upper receivers or simply protecting your expensive spare receivers from being accidentally damaged.
