kitplanenut - here's a quote from 2009 that should reassure you...
"Todays firearms manufactures have quit putting iron sights on rifles to save money.
And the new generation of shooters are brain-washed into thinking they need a 12X-20x, 30mm, Tackycool scope to shoot a deer 100 yards away.
And back then, scopes were a "new thing" for riflemen weaned on M-1 Garands in WWII, and they didn't trust scopes yet.
I'm not saying todays better scopes are not clearer and tougher and better then a Weaver K series scope made 50 years ago.
But I have used Weaver K2.5, K-3, K-4, K-6, and K-10's in the years since my first on in 1960, and have yet to break one. Oh! I forgot the old Weaver V-9 on my 25-06!
And I couldn't be more satisfied with their performance on game or targets".
