Took a few weeks to put this on a 9 mm PCC upper. Now it's on and sighted in. I think is going to work out very well, once I get used to the new sight picture. I haven't shot it much yet so I will post more later.
Mk2 - Non-Tritium Open Sight Rail Mounted
Nice site makes these old eyes feel young again. I put this on a Springer pistol which has a lot of crazy recoil and it holds center making it fun to shoot.
Very well constructed, easy adjustments, and overall better than a red dot for me. Mounted it infront of the installed dotsight and adjusted the SeeAll to the dot. I recommend playing around with how much distance the optic is from your eye, i have best results with it being at the furthest slot away from my eyes.
I had eye surgery a number of years ago. One eye sees distance and the other sees up close. Very difficult for me to shoot a pistol. But not with this awesome tool! 500 stars
