The XS Sights Minimalist Optic Mount for Glock 19 with ACRO footprint is a complete mounting and backup sight system engineered to get you running an enclosed optic without the usual guesswork. If you're building a duty gun, duty backup, or competition rig on a Glock 19 MOS, this combo kit solves the co-witness puzzle in one box—optic plate, front sight, rear sight, screws, torx bit, and threadlocker all included. You get a factory-correct answer rather than chasing height-over-bore calculations.

XS Sights designs their minimalist sights to stay out of your way. The low co-witness height keeps the rear sight picture low and unobstructed in the optic window, so when you're looking through the ACRO, you're not distracted by a huge sight blade in your peripheral. The blacked-out, serrated rear sight reduces glare; you get your choice of a tritium or non-tritium front sight for your lighting preference. The whole system is CNC machined from American-made steel and treated with BlackNitride for corrosion resistance—this is hardware built to survive hard use and salt air.

The optic plate itself includes 30% more thread engagement than some competitors, which matters when you're mounting a precision optic. Everything threads into a Glock MOS slide cut for ACRO-footprint optics (Glock 19 compatibility confirmed; the system also fits 17, 34, 45, 47, and 49 MOS models). Blue threadlocker comes on the assembly screws; red threadlocker is included for the optic mounting. This is the kind of detail kit that saves you a trip back to the bench.
