|This latch is a nice extension length and real good modification. I had the same another AR and like it a lot. The following works well for me to get it installed.
Drive out the pin with a 1/16 punch, remove the existing latch. From the top of the charging handle position the new latch and push to compress the spring and line up the holes. Slide the 1/16 punch down into the hole and it will hold the latch in position. Now flip it over and lay it on your vice top or something similar so that the punch is hanging free. Take the pin and push it into the hole on the underside so it is just started. now tap it lightly repeatedly and you will drive it in and it will push out the punch. Finish off with the punch to drive it fully in. You are done.|
