    AT3D Cover for HS507C-X2

    Posted by Warren on Mar 10th 2021

    A useful cover that should have been included with the $307 optics. Fits well and made from a durable product. A bit expensive but it’s a ‘buy once’ product that will protect the initial investment when stored or transported.

    This protects my optic and fits perfectly, removes fast with no effort, yet stays in place when needed. I ordered wrong color, and an email later, I had the color I desired. Great customer service. Getting another optic soon, and I will be buying another.

    Almost 5 stars

    The products is daily heavy duty and seems like it will be very durable. Cover needs to have a lip on the bottom to hold onto the optic. It is only holding on with basic surface contact friction. I would not home through the woods and expect it to still be there when you make camp. Optic mounted on 22/45 lite with shadow v2.0 universal plate.
