YHM Forearm End Cap "A" for standard .750 Barrel

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.
The "B" model is for heavy barrels and has an inside diameter of 1.050
inches, and the "A" model is for all other barrels and has an inside
diameter of 0.925 inches.
