Sight optimization for LG

This sighting optimization is screwed onto the existing sight. It consists of a high-quality material with a 1.6 mm tube screwed in the middle. So you no longer have to look through the normal sight with about 4 mm, but have the target in sight with 1.6 mm. I had the part made by a friend who is a precision mechanic... actually just for myself .but he is a sport shooter himself and then made several of them.I have now tried it with my friend over several weeks... both improved by about at least 2 rings. You have to get used to it... but it's obvious... do I take the target in sight with about 4 mm or only with 1.6 mm. What I have to clarify, however... we are both benchrest shooters. How it works in standing position I cannot say.Unfortunately, I cannot publish pictures at the moment... but I will catch up on that very quickly
