*Slide cut option is for optics that are mounted down into the slide. It is cut away to allow it to sit fully onto the optic when mounted in the slide. If your optic is on a plate or flush with your slide you don't need the slide cut.*

    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.

    Going out of their way to please.

    Purchased this cover for my Holosun 407. Apparently this was a new model, because the cover was loose. Caleb contacted me and wanted to make it right. I gave him the measurements of my Holosun and today I received my new cover. It fit perfectly. Talk about going out of your way to please!! I could not recommend this company enough, because they aim to please. Thank you Caleb!!!

    Holoson 507c optic cover

    Posted by Ray Yparraguirre on May 17th 2020

    This is my second optic cover from Amarok Tactical. Fits like a glove. I understand that 3D printing may have a rough finish but this thing will last forever. For the price great value.
