Whats Different Between Version 1 vs Version 2?

On our original mount there were just 2 holes drilled into the mount and it would be attached by machine screws with locking washers. For most people that worked well but some complained that the mount would loosen while swaging. On the mount we have drilled and countersunk the holes as deep as we could to do 2 things. 1. By using the largest head sized tapered screws that we could source, the surface area of the tapered head will lock down the mount far better than the original design and 2. By going as deep as we could go with the taper, we are virtually eliminating any flex from the screws. Combine that with lowering the mounting holes by 0.010, the mount will lock into place securely with very little flex or movement.
