I've owned a pristine Win 75 target .22 for years. Lyman peep sights and heavy barrel. Wonderful older gun probably late 4o's earlay 50's. It has a pair of narrow bases on the barrel about 8" apart I assume set up for one of the older Unertl or Lyman ong scopes. Im guessing it was used for paper at 50'. My question is can I make this gun more useful for shooting varmints without a $5-600 + old Long scope? I'm not interested in drilling and tappin the reciever. It needs to be left just like it came. Maybe a long eye relief or pistol scope set up on the old bases. Somebody out there seen this done succesfully?Thanks for your experience and input in advance.
