After the success of the Front Sight Focus String, I wanted to see if there was a way to make the training more realistic and effective. I stumbled across a set of square black beads with white writing on each one. That’s when the bulb popped up above my head.

The closer you can get your training to “reality” – the faster you’ll learn. Because your front sight post is black and flat (If not get it fixed) and I teach shooters to put a small white mark
on their sights to improve their ability to focus, the Advanced Focus String is the perfect tool for improving your ability to focus on your front sight post.
