Has potential - SightMark XT-3 Tactical Magnifier

I had previously checked out the XT-3 at a retail store while researching a magnyfier . When it arrived I was generally satisfied until I tried to mount it. While SightMark doesn’t claim this is a QD mount, mounting this device was very difficult. I assume others will likely want to transfer the magnyfier from one gun to another. Each time this would be done would be a tedious operation. The springs providing closure tension easily escape their tracks. I definitely would not attempt a swap in the field. If SightMark addresses this issue, I would consider the magnyfier.
