This thing affectionately known as a "boat anchor" is only good for range practice. If Ruger made this optics ready and threw in at resonable cost one of Chinese holosights (it would not be expensive venture because decent ones can be had for around $60 per unit at Alibaba, therefore, ordered in bulk the price would be very reasonable) they would probably sell a bunch. I would check for feedback at Ruger forums where many of their fans go.
