Poor quality - Leapers UTG LE Rated Tri-Rail/2 Slot Angle Mount w/ Integral QD Lever Lock System

When fastening the mount to my rails, I had to fiddle with the adjustment screw a ton to get it to mount somewhat solidly, but there was still a little movement parallel to the rails to it. A sixteenth more of a screw turn and it really felt like the screw or lever would break.
Pros: Inexpensive
Cons: Slots on mount don't line up with picatinny rail slots, lots of play in where it attaches to rail, QD lever makes a third of the rail unusableQD lever doesn't make for a solid mount, machining quality is poor, all the surfaces seem soft and rounded instead of crisp and precise
