You'll be happy to expose me? It's already painfully obvious that you haven't a clue of what you're talking about. It's a clamp and it locks in position, does it not? Well, the GDI does anyway. Secondly, what makes one mount superior over the other is not only the clamp/locking mechanism but also the amount of bearing surface the mount has. If you weren't a moron then you'd know this already. The Bobro clamps onto the rail with nowhere near the amount of surface as the GDI and other mounts yet people who don't know shit, such as yourself, still hail them just like they do Larue mounts.
As for POF being overpriced, I'd hardly consider $2500 being overpriced when it's every bit as accurate and moreso than the higher priced competition. But keep telling yourself that there's no benefit so you'll feel better about owning an inferior product.
Now, what was that you were saying about exposing me? You've exposed nothing but your own stupidity.
Not even close.
All scope mounts have a clamp, and only some have a lock.
The 2 mechanisms are independent of one another.
As for how much bearing surface is appropriate, enough to avoid compressive forces given the materials involved is enough, a little more is appropriate (to account for variation), and too much is worthless; adds weight and cost and increases the likelihood of introduction of error such as introduction of foreign matter between the mating surfaces.
Exactly how much experience do you have with design, materials, measuring, repeatability, etc., anyway?
I have decades of experience in all of them... machine shop, tool & die, Injection mold design, machine design, CAD/CAM, CNC manufacturing, etc.
I've built hundreds if not thousands of fixtures for precision location of parts, and I can say with 100% assurance that the Bobro mount has all the elements required for repeatability.
Don't worry about it, though, the world needs ditch diggers, too.
