Use these screw-in end caps to dress up and provide protection for the end of your YHM forearm. Does not interfere with the free floating of your barrel and helps keep out debris. Drilled to allow for proper heat venting. Both models fit all handguards that will accept our endcaps. These are very easy to install. Just place a small amount of Loc-Tite (included) on the threads and screw it into the rail until flush.

15/16" inside diameter (YHM-9484A) (This is the one you'll want if your barrel is the typical M4 diameter (.750") or smaller.)
