Sweet March 19, 2019 Reviewer: Gunner from USA These are really neat, and a very cool way to add some "night" sight capability. Probably need to repaint with some glow in the dark paint, but even with the current white on there that no longer glows, it helps in low light. A very eastern bloc way of doing things for sure, but seems like it would work. No booklet with the 4 that I purchased, unlike the other reviewer that said he got an original instruction booklet. Got them on sale for a great price.
