I have a D C Engineering reciever mount for one of my two SKS rifles. I choose it because it was the lowest and best reciever mount on the market when I was tricking out the rifle for my youngest son as an enducement for him to take hunter training.
I wanted a low scope mount for the Tasco Red Dot sight as the Choate plastic stock had a low monte carlo cheek piece on it and I wanted consistent head/eye to rifle relationship.
I saw a comparison of all scope mounts on the web a while back and the shocker to me was that the D C Scope mount is the second best such reciever mount. It comes in right after a glue on to the reciever scope mount kit.

When I bought the mount from them over a decade ago, I told them that my red dot sight had rings and they reduced the price from the mount plus ring value on what they sent to me. Good folks (at least back then).
Let us know what you do. My mount has been very accurate and had no problems, but then I am not using a 20x scope either.
