FO front sight
This fiber optic sight is very easy to install. I also greatly improves target acquisition even in low light settings.

Just perfect
This sight was super easy to install. It made a big difference on the shooting approach. My son stated that he was able to move quicker through his targets. It was just a perfect addition to his gun for competition.

Ruger 22/45 front fiber optic sight
I'm very pleased with the sight. It went on easily and looks like it belongs there. It's a much better front sight than the blacked out one that came on the pistol!

Fiber optic front sight
Attractive price, highly visible, looks great and less than 5 minutes to install - Great front sight! Awesome for fast target acquisition, but a bit less than ideal for precision shooting, due to the diameter of the fiber optic - would be nice if different diameter options were offered; e.g. smaller diameter for more precision

great addition
Perfect. Easy to pick up dot. Big improvement.

Ruger Sight 22/45
Sight was easy to install and I can actually see it from the rear sight which was not the case with the factory sight on my Ruger 22/45.
