Update on previous post - JP Enterprises JPoint Circle Dot Micro-Electronic Reflex Sight

Well, the sight base to fit my Ruger Mark III Hunter finally arrived. This base uses the dovetail of the rear sight (replaces the sight). It was a little tight - the gunsmith had to file it a bit then hammer it in with an aluminum drift. Be careful if you choose to do this yourself. The base is anodized aluminum and hard yet can be marred if the wrong drift is used.

Since the weather is cold and wet I went to the indoor range to sight in. Sighting was fast with a solid rest. The small dot in the middle of the circle is fast and easy to get on target over just the dot alone. I would think this would be a huge advantage in competition shooting.

My main attraction to this sight is I can use it without my bifocal contact lenses which are needed for computer use and likewise seeing the pistol sights, but they adversely affect distance focus. The sight base works well using the dovetail because it keeps the sight low to the bore and makes for a very simple and clean looking installation.

So far (at the range) it works wonderfully. I shot 1" groups with standard 22LR ammo out of my Mark III hunter at 8 -10 yards easily. I'm really looking forward to spring weather when the ground squirrels are out. I shot at those last year with open sights with my Ruger 22/45 at 10 to 50-plus yards, but the contacts make things fuzzy after about 15 yards. With this new JPoint I'm hoping things are clearer and shots much more accurate.

Final thoughts at this point: be aware that you must remove the sight from the base to change the battery, which may change your zero requiring a reset. Also, the sight is always on (no on-off switch) but when covered it goes to it's lowest illumination setting so it supposed to last for months. It automatically adjust its brightness to ambient lighting conditions. So far, sighting in at the indoor range with low light and pointing it around outside in bright sunlight has resulted in good visibility of the dots in all cases. We'll see when it comes time for actual outdoor plinking.
