I have a Butler Creek .920 bull barrel on my 10/22 and love it with the exception of having to rely on a scope to do my shooting. I would like to have a set of iron sights installed on this barrel. Is anyone out there aware of any iron sights that are available for the Ruger 10/22 rifle with the .920 bull barrels? If there is not a specifically designed sight set for this barrel, is anyone aware of anyone who has made an iron sight set work on this type of barrel? I have scoured the internet with no luck so far. Thanks in advance for any information anyone has in regards to this issue.
