I bought a cheaper mount previously that wobbled like a toy so bit the bullet and paid for a professional mount. This one is top notch. It fitd very tight with no wobble and I actually prefer the 180 degree swing rather than the standard flip to the side mount. It allows the mount to be placed as far to the back of the rail as possible to get the magnifier closer to the correct eye position. It also swings totally out of the way to the side of your choice without having to push it forward so it can be closer to the red dot sight. Getting the proper tension adjustment takes a bit of trial and error but once set it is tight and secure. I really like it a lot.
Pros: Fits tight, no wobble, Flip around style
Cons: High price
