Very poorly designed. - Primary Arms Flip To Side Magnifier Mount w/ Illuminated ACSS Cyclops Green Reticle

Do not purchase this mount. I love the optics that Primary Arms makes, but this mount is very poorly designed. After mounting my magnifier and heading to the range I noticed I kept having to move my eye closer and closer to see through the magnifier. I finally noticed the magnifier was no longer centered on the top of my rifle. It was the pin that holds it in position sliding out of position that was causing this. To move the mount to the side and then back into postition you have to pull toward the stock to relieve the tension a spring places on the detent pin. However there is nothing to keep the detent pin from moving out of place. Luckily I caught this flaw before the detent pin fell out. When the pin slides around it throws off the position of the magnifier.
