I am assembling parts to build my daughter a AR in 300 BO. She has a deer rifle so this would just be for hogs/varmints/etc not for blind or long distance hunting. She is also pretty small at 10 years old so trying to cut down on the weight of the rifle as much as I can.

So what would be a decent, fairly inexpensive scope to go with? I see some fairly cheap small scopes online, but I don't want to waste money on a piece of junk scope.

Athlon talos btr 1-4. I have one. It’s great.

I have installed a few of these on ARs:

At $100 sale price, it is pretty hard to beat.

Thanks guys, I will check them out

I would put a Burris Fullfield II 2-7x35, VX-Freedom 2-7x33 or VX-Freedom 1.25-4x20 on it.
