Triangle prism for front sight

[EdR]

Another shooter was telling me about a insert for a front sight that made it look like you you were centering 3 bulls at once kinda lika a prism of some sort. I guess it is supposed to make you focus more. Its not a triangle apeture though. Anybody ever heard of this where can you get them?

If it really has a prism, you can't use it under ISSF rules. OK for NRA conventional. This one has gone around a bunch of times, some folks swear by it, some just swear at it. A bit like aperture size, everybody 'knows' the right answer. I shoot with an adjustable, huge by most folks standards, and have little trouble calling my shots. Not always happy with what I call them, but that's another matter.

Bottom line: try it. If it works for you, great. Contact the folks who advertise in Shooting Sports and USA Shooting news. Somebody will have the item or know where to get one.
