This XS Sights set brings together two of the most respected pieces in the backup iron sight world: the CSAT rear aperture designed by Master Sgt. Paul Howe and the XS tritium stripe front post. It rides on Samson quick flip-up bases machined from aluminum with stainless steel clamps and a hard coat anodized finish, and it clamps onto any standard 1913 Picatinny rail. The bodies fold flat when you are running a red dot or magnified optic, then pop up and lock under spring pressure when you need them, with no protruding knobs or levers hanging out to catch on gear.
The rear sight is the real story here. The CSAT aperture combines a notch and post at the top for a 7 yard zero with a small peep below it zeroed at 100 yards, which lets you account for the roughly 2.5 inch offset between the bore and the sight line without changing your grip or flipping anything. Up close in a room you use the notch like a set of pistol sights. Reach out to distance and you drop into the peep. There is also a same-plane large battle aperture you can flip to for a wider field of view, and it holds the same zero the whole time. Howe built it so you can zero at 7 yards, confirm at 100, and cut your zeroing time roughly in half.
The front post measures 0.105 inches wide and carries a vertical green tritium stripe framed by a white painted outline. That combination gives you a bright, high-contrast aiming point in daylight and a glowing reference when the light drops off. It is a genuinely fast sight picture whether you are shooting at noon or well after sunset.
These are mil-spec dimensioned and made for AR-15 and MSR-style rifles and carbines with same plane, same height gas blocks and rails. The sights install with a standard screwdriver and are backed by XS Sights, whose tritium illumination carries a multi-year glow warranty. For anyone who wants irons that do more than just sit there as a last resort, this set earns its spot on the rail.
The CSAT aperture gives you a notch and post at the top for a 7 yard zero and a small peep below it for a 100 yard zero. Up close you use the notch like pistol sights to account for sight-over-bore offset, and at distance you drop into the peep. There is also a larger same-plane battle aperture you can flip to for a wider field of view, and every option holds the same zero.
They are manual flip-up sights. You raise each sight body by hand and it locks securely in place under spring pressure once it is up. There are no push-button releases or spring-deploy mechanisms to worry about.
The Samson bases are mil-spec dimensioned and clamp onto any standard 1913 Picatinny rail using a common screwdriver. This is a same plane set, so it is designed for rifles with same-height gas blocks and rails. It suits most AR-15 and MSR-style carbines running a flat-top setup.
The 0.105 inch front post carries a green tritium stripe surrounded by a white painted outline, so you get a glowing aiming reference in the dark and a high-contrast picture in daylight. Tritium naturally dims over its lifespan, and XS backs the illumination with a multi-year warranty. It gives you a usable sight picture across a wide range of lighting conditions.
