Easy to mount and sight in. very nicely constructed, good quality. - Nikon P-Tactical Superdot 2 MOA Red Dot Sight

I am very pleased how well the Superdot has performed. I used the low-mount setup and installed it on my old S&W 22 A-1 pistol, it worked liked a champ. It fits perfectly on the weaver mount. It took roughly one magazine to get it sighted in at 25 yards. The view through the lens is very clear and the 2 moa dot is sharp. I also recently purchased the Nikon P-Tactical Spur and installed it on my Ruger 22/45 lite. It took longer to sight in the Spur than the Superdot. Regardless, I am very pleased with the controls and operation of both red dot systems. The reason I chose the Nikon sights is because of current long delays & delivery uncertainty for comparable Vortex products. After the performance of both sights I'm very happy that I selected the Nikon units (although the lifetime warranty for the Vortex products would have been nice). Until ammunition shortages get resolved I'll continue to use the Nikon Superdot on my 22 pistol. I am looking forward to trying the Superdot (with the included high mount) on my AR-15. Meanwhile, I'll continue to have fun burning through 22 ammo.
