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.

Great sight !
High quality, perfect fit for my Ruger Mark 4...1000 times better than the factory front sight

Plus eagle eye
If I center the eagle eye on my Mark lVi shoot high. There isn’t enough screw adjustment to allow that so I center the green dot on the bottom of the eagle eye

Review Tandemkross front sight
I am very pleased with my fiber optic front sight from Tandemkross. It was no problem to put it on my Taurus TX-22. I is a world of difference to see with my aged eyesight. I makes a WORLD of difference! The shipping was quick and the whole thing has been a good experience. I will buy from Tandemkross again. I need a fiber optic sight for my Taurus G3 as well, and it will be purchased from Tandemkross. Buy one, you won't regret it. :)
