“This mount is well made and fit the sight dovetail perfectly. It only took a couple of light taps with a plastic faced gunsmith hammer to center the mount on the gun receiver . The only problem was that the short screws were to short to engage. The long screws were to long by approximately 1/16" which caused them to bottom out before they secured the Sig Sauer Romeo3 red dot sight. It took a few minutes to file the excess material from the screws and tightly secure the sight to the weapon.”
