I've wanted to do this set-up for a while. I bought the Ruger MK3 last fall. It is stock other than the Hogue grips. They are a must IMHO. They fit my hand like a nice soft glove. I hated the factory checkered grips. But these grips give the Ruger the nice grip that the browning buckmark (my other choice when choosing a .22 pistol) had. Glad I got the Ruger. Anyways, I got the crown to top it all off last week, the fastfire 3 with ruger dovetail mount. I always drooled over pictures or people Rugers with this setup. It looks like a pistol from starwars or something. The fastfire 3 is a great improvement over the last it seems. Easy to adjust windage and elevation, and 1 auto and 3 manual brightness settings. I couldn't imagine having the old model with only the auto setting. And the older fastfires you had to loosen a setscrew before making either windage or elevation adjustment :-s Cant wait to get this thing to the range 8) Will report back Wanna kill these ads?
