It's very tiny, but it did work better than what i had. - Swampfox Wolverine Tritium Stealth Sights

I needed a bigger better brighter front site for my Rost Martin RMIC that co witnessed with the green dot it came with. Since they use Springfield machining I gave this a try. It fit, but it looks nice and tall in the picture, but like a bad Chinese Amazon product it came sized for a 1/4 teaspoon world. However it does co witness just a little less than 1/3. It is much more visible than the white paint factory dot. So a minimal suckcess at a great price. 1/2 Co witness,double dot girth, and brighter night optic is next. Rearsite would not fit gun's machining, but would of beento low to work if it did fit.
