I too used to always pull the barrels on those rifles as I read they were not accurtate - but now know that you can't trust everything gunwriters say
I know now that many of those rifles shot very well - plus many also had chrome lined barrels, which is a big asset in wet country
The J.C. Higgins Model 50 is very
accurate - so much so that you can rebarrel one and you'll be lucky if the $500 you'll spend doing it gives you a rifle that shoots as well as it did before.
I can't believe that anyone who actually shot one would write otherwise.
Anyway, the early 50s had a sight that mounted on the very rear of the barrel, like the one shown:
Later Model 50s had a boss soldered to the barrel and a similar looking sight mounted the other way around.
