Nikon or pentax; for 150 bucks, you get a lot of scope, with Japanese glass, still very desirable.
Both have a no questions asked, lifetime return policy, just like Leupold.
Tasco Varmint series; I have had these now for about 5 years, they have never lost zero, and have been repeatable; the glass is pretty good, even at high
power; I usually keep them on 24x. I have had them on everything from 22's, to 308 superlights, and
they have never lost zero. I have one on a hunting/long range 243 right now.
They will be in the 100+ dollar range.
NOW FOR THE SLEEPER; Tasco makes a scope that is ADULT RATED,
AIR RIFLE RATED, SPRING PISTON RATED. Which means, it will have lots of
steel ,and should be double tough to take recoil. it is also a 3x9x32, which
means it is not very big and overpowering. it also has an ajustable AO, and
it goes down to about 10 ft., which is awesome!!!! anything that can get Prllax
free under 25 yds is good, especially if you squirrel hunt. I have used these
scopes on rimfires for years, but have no long term notes for it, on centerfires, though
I have had them on centerfires, and have a new one in the box, waiting on a new
home to ride upon, as soon as I decide what!!!
Be careful if you buy one, there is this model, and another model without the
adjustable AO, they are both called golden Antler series, though.
Best thing about it? it is 40 bucks or so...
