You get what you pay for - Monstrum Slim Profile Series Cantilever Offset Dual Ring Picatinny Scope Mount, 30mm

Ignoring the tried and true notion of getting what you paid for, I tried to cheap out and get as much bang for the least buck. Big mistake with this mount. There is a reason the quick detach mounts are way more expensive than regular ones and it was in that mechanism that this product failed.

One of the clamp bolts threads stripped during tightening/latching of the initial install. The design of the latch and the way it applies tension during tightening makes it difficult to find a decent sweet spot of tightness so you can latch and undo the latch...which is it's intended purpose. Also, after unlatching, the relatching needs more more adjustment because it doesn't keep it's originally set tension.

Finally, after giving up on the QD and shopping for regular two-ring mounts, I read reviews of the Weaver tactical rings that are the same price. One of the reviewers mentioned that they have strong, square-shaped clamp bolts and that was a feature to look for. They are stronger and prevent foward/rearward shift in the picatinny slots.

So I'm going with the Weavers.
