Again, this is a no cost solution and your "inexpensive" might not be so to others and I'd bet with out looking that they are $35 +
Sheesh,why do guys have to jump in with something else especially when the info is bogus. grin
Wish I could find someone around here with cash who was willing to "bet without looking"
A rear sight from Track of the Wolf cost $7.00 to $ 8.00.
If your rifle didn't have the dovetail already cut (mine did) it does not require a milling machine or a gunsmith to cut one. I do it all the time, by hand, with a file.
This is a link to a Midway video by Larry Potterfield showing how to hand cut a dovetail in a rifle barrel.
https://www.youtube.com/watch?v=W60yBwzipKAMaybe $8.00 and use of a file is expensive to you.
Accura Glass will cost you $24.00.
Maybe my math is different from yours?
Yeah, it's annoying when guys jump in with bogus info.
I hate that...
Almost as much as guys who post "wisdom" on how to solve a problem through "creative tinkering" instead of fixing it right the first time. Jeesh....
