Once again Ausie-guy nailed it - the 2nd & 3rd axis, gang & individual micro adjusts, round pin guard, level, centering wire, bubble, and ' no clamp' adjustments make this thing awesome.

And - for what it' s worth - I know of a shop that placed an order NO EARLIER than 3/21 and the sight is supposed to arrive tomorrow - 4/1 - that' s 7 business days.
