I INSTALLED A HIND SIGHT ON MY LX. IT ONLY TOOK A FEW SHOTS TO LEARN THAT YOUR ANCHOR SPOT IS THE MOST IMPORTANT THING. I HAVE SHOT A PEEP ALL MY LIFE WITH A KELLER PENDULUM SIGHT. I AM ONLY SHOOTING 1 PIN ON THE HIND SIGHT. I PUT A TRUGLO TRITIUM PIN ON THAT GLOWS IN DARK. IT MADE A BIG DIFFERENCE IN SEEING THE TARGET.
