    Top Tier Optics

    I really couldn't be happier. I did a side-by-side comparison with my 7-35 ATACR looking at a milk jug 1750m away. The ATACR is great, but it was tough to make out the gap in the handle. With the ZC 840 that little gap was VERY clear and could even lay the center of the reticle right on it. This is a perfect fit for my 300 PRC.

    ZCO 8-40x56 scope

    The finest rifle scope I’ve ever owned by far. The optics, construction, and features are without peer. It’s also the most handsome scope I’ve ever seen. It’s not a budget scope by any means but if you want the very best available, the price is understandable. You can’t do better than CSTactical to order this or any other quality optic from. They have good prices, excellent service, knowledge of the product, and are very helpful in answering any questions you may have. Their staff is top notch all the way.
