Hiya Guys ... So my mailman came through my neighborhood today and dropped off my see-thru Optics rail for my 10/22 . I chose the see thru rail because I prefer to have the option of being able to use the Optics and the iron sights, that's how I prefer to set all my rifles up if I can. Unfortunately the basic rail that sit's flat on top of the receiver doesn't give you that option. https://m.ebay.com/itm/Ruger-10-22-1022-High-Profile-See-Thru-PicatinnyWeaver-Base-Scope-Mount-w-Screws/152107419610?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 needless to say I pulled out my bottle of medium blue thread lock and got to work installing it which almost seemed like an exercise in futility. Whoever designed flat head screws should be put against the wall, given a blindfold and a last cigarette and Sumarily Shot . I finally got the rail installed and since I had a set of tall Weaver rings I decided to put my vintage Weaver K4-W fixed 4x wideangle scope on this since it's naturally not as accurate as my high standard or Stevens savage. As far as the glass goes It's Made in Japan so the clarity and the magnification are excellent and it's Crystal Clear as expected from Japanese glass. A 50-yard shot is like I've got a seat in the front row, but 100 yards or so is about the maximum comfort zone for this magnification. What's really surprising is the eye relief 4 the scope as old as this. Believe it or not this thing has a 4.5" eye relief, you don't find that very often with vintage glass .
