You may be able to use the existing bead, but the added height of the picatinny base will make an elevated ghost ring style sight much easier to use.

Mo, guest, from NY, United States, asked on March 05, 2020

Will this fit sxp that has a factory drilled receiver

A
Answered by Brandon, member, from UT, United States, on March 19, 2021

The factory tapped receiver of the Winchester SXP does not match the pattern of the Mossberg 500/590. To fit the Winchester SXP, it will require a gunsmith to drill and tap receiver holes matching the Mossberg pattern, or new holes to be drilled in the ATI Halo.
