I need a new scope for a Remington 700 chambered in .308. Thinking something 4-12 x 40-50mm. I'm trying to keep this project >$1000 total so after other accessories, replacement parts and gunsmithing I'm left with no more than $200 for optics for now. I've read good things about Barska, except that they can be blurry around 300 yards, which makes me hesitate. I'm fairly new to optics/distance so help is appreciated.
