This kit pairs the AT3 ACE pistol red dot with a UTG 45-degree offset mount for use as a close-range secondary optic alongside a scope or LPVO. The ACE mounts directly to the RMR-pattern plate, while the offset position lets you transition between optics by rotating the rifle instead of adjusting the primary optic. Choose between a red or green 3 MOA reticle.
Note: The offset mount installs on the right side of the firearm and cannot be reversed for left-side mounting. Only use the included #6-48 screws to secure the ACE to the UTG mount.
