I call the Millett Angle-Lock rings "Mangle" locks... because they will mangle your scope.
Here's why:
Each ring will drift side to side depending on the amount you have the rail mounting screws turned in. Millett claims this is some sort of "built in" windage compensation capability.
However, when you drift the front ring lateral of the rear ring (or vice versa) the scope tube actually bends a few thousandths of an inch one way or the other. Think about it this way: If you drift the rear ring to one side or the other... the front ring stays firm in position. It does not swivel like a Redfield/Leupold front mount to allow the ring saddles to line up!
So you end up literally bending the scope tube one way or the other as you tighten the "mangle" lock rings.
The only way to avoid this is the run the rail mounting screws all the way in on one side (same side on both the front and rear rings), then tighten the rings to the Weaver rail using the opposing screws... then hope there is no manufacturing error in the sizing of the rings, so your scope tube remains linear.
So again... since these rings slide left to right in the notch in the Weaver base, they can and will get off axis with each other, causing the scope tube to be stressed significantly as you tighten all the screws down. The pressure will be highest in the diagonally opposing corners of the ring saddles... i.e. the front left edge of the ring and the rear right edge of the ring will "dig in" to the scope tube.
I would avoid the mangle locks.

Dan nailed it. His analysis is spot on!!!
The angle locks are the rings I was referring to. They are junk, in the fullest meaning of the word junk too.
And I'm betting that fw707's analysis "is spot on!!!"
Read the mounting directions and like fw707 stated, align them correctly, and they actually work quite well. If you take short cuts, they probably won't work very well.
