Any update?
Other than I bought a crappy no-name brand made in China red dot that won't hit the broad side of a barn there is no update, it's hard to measure if the scope mount is solid and will keep the red dot zeroed in when the red dot is garbage and don't deserve to be mounted on a water pistol. But I do have a Carl Zeiss red dot on the way that I will arrive next weekend.
But so far the scope mount have been of no issue regarding the functioning of the pistol
