I've been thinking about this for a while now and the only way I can make any sense out of the above statement, is that you must be talking about a different pivot system to the EAW pivot mount which I was referring to.
The EAW pivot mount that I use has a small ball ended spring loaded lever which is pushed upward to release the lock mechanism, then the scope is rotated 90 degrees and lifted off the rifle.
Once you are used to it's operation, and have practised a little, the scope comes off super fast.

I'm NOT talking 2 seconds or thereabouts for this.
Nowhere near that long!
It takes less than 1 second from when you hit the lever to when the scope is totally clear of the gun.
Putting the scope back on takes a tiny bit longer, between 1 to 1.2 seconds, from scope off the rifle, to back on and lever locked.

Maybe the release system on the pivot mount that you have found to be so slow, is of a different type, one which takes longer to operate?

Honestly, I cannot see how anyone would require a scope to be removed or replaced any faster than the EAW style I have described here, and I rather doubt that any claw mount system is going to be any faster than that type of pivot system.

The EAW system I use may well be a "cheaper" system than the claw mount, but I do not agree that it is slower in operation to any noticable degree.
