I found 2 that may work. NC Star Mark III Tactical AR Scope and Courage Series Compact scope. Any know either of these? Also should I go 4x32 or 6x32 and what does the second #(32) mean? I know the 4 and the 6 are the zome times. Right??
Um.
Yeah.
Get the iron sights I gave you the link to.
NCSTAR are cheap Chicom glass. Some people have good luck with them, but many people don't. Zero starts wandering, and you now have a useless weight on top of your rifle. Don't know anything about the others, but...I'll stand by my original statement...but if one simply must, the only one worth considering is a Nikon rimfire scope...usually can be found for around $100 or so.
Seriously--if you're going to consider this a survival rifle, reliable and durable are a heck of a lot more important than neato-cool.
And how scopes work--the first number is the magnification. the second number is how big the objective lens (the one facing the target) is. If you see a scope described as, for example, a 3-9x40, that means it has a variable zoom, from 3 to 9 power, with a 40mm objective lens.
