This Talley Mounting Systems Micro Dot Picatinny rail gives Winchester Super X shotgun owners a clean way to add a red dot without a gunsmith cutting the receiver. It fits the SX2, SX3, and SX4 (and the SXP pump variant in Talley's lineup), turning a bead-sighted scattergun into a fast-acquisition platform for turkey hunting, slug work, or home defense. The rail is built specifically for mini reflex sights and micro red dot optics, with a compact footprint that keeps weight and bulk down. Buyers running the Winchester sx4 Picatinny rail get a direct-fit mounting solution that holds zero through heavy field use.
Talley machines this rail entirely on CNC equipment from high grade 7000 series aluminum alloy, then hard-coat anodizes it to 65 Rockwell for surface hardness that resists dings and wear. The mounting interface is cut to MIL-STD-1913 dimensions, so any micro red dot or mini reflex sight built to that standard drops straight on. The design uses the two most rearward receiver mounting holes, which positions the optic correctly over the bore for a natural cheek weld and proper eye box. Each rail ships with the mounting screws, a tension screw, and a wrench, so installation needs nothing beyond what's in the box. It's a one-piece base, made in America and backed by Talley's money back guarantee.
If you're setting up a turkey gun, a slug barrel for deer, or a defensive Super X, this rail is the foundation for a dependable optic mount. Pair it with a micro red dot for both eyes-open shooting on moving targets and fast target transitions in tight quarters. Shooters running other platforms can find matching options like the Remington 870 Micro Dot rail or the Mossberg shotgun version.

It fits the Winchester Super X series, covering the SX2, SX3, and SX4 semi-autos. Talley also offers this same Micro Dot rail in an SXP pump version for that shotgun. It mounts to the receiver using the two most rearward existing mounting holes for correct optic placement over the bore.
The rail is cut to MIL-STD-1913 Picatinny dimensions, so any micro red dot or mini reflex sight built to that standard mounts directly. Its minimized footprint is sized specifically for compact reflex and micro red dot optics rather than full-size tube sights.
Yes. Each rail ships with the mounting screws, a tension screw, and a wrench. No additional hardware is required for installation onto the Super X receiver.
Talley machines it entirely from high grade 7000 series aluminum alloy and hard-coat anodizes it to 65 Rockwell. That combination gives a strong, lightweight base with a durable surface finish that holds up to recoil and field handling. It's a one-piece design made in America.
