Mission First Tactical
The Mission First Tactical BUPSWR flip-up rear sight for AR-platform rifles brings durability and practical versatility to your rifle's backup sighting system. Built from combat-proven polyamide polymer, this folding rear sight is engineered to handle the rigors of the range and field while staying compact when not in use. Whether you're running a primary optic and need a reliable secondary or building a rifle with iron sights as your main aiming system, this sight delivers the speed and precision shooters demand.
The dual-aperture design is the real workhorse here—one aperture for close-range target work where quick acquisition matters, and another for longer-distance shooting that demands precision. A heavy-duty protective shroud guards both apertures from debris, impacts, and environmental wear, extending the life of your sight investment. The design mounts to any standard Picatinny rail, making it compatible with the vast majority of modern AR setups without adapters or gunsmithing.
Adjustments are made via a flat-blade tool (not included), allowing you to dial in your sight picture and make MOA corrections as needed. The folding design means you can rotate the sight down when you don't need it, clearing your sight line for a mounted optic or simply reducing profile. It's the kind of no-fuss, no-frills backup iron sight that gets out of your way until you need it.

Yes. The Mission First Tactical BUPSWR mounts to any standard Picatinny rail found on AR-platform rifles, including AR-15s, AR-10s, and other modulars using standard mil-spec rails.
Absolutely. The folding design lets you rotate the sight down and out of the way when you're using a primary optic like a scope or red dot. It's there as a backup if your primary fails or when you need irons for close-quarters work.
A flat-blade tool is required to make windage adjustments and MOA corrections. The tool is not included with the sight, but any standard flathead screwdriver will work.
One aperture is sized for rapid target acquisition at close range, while the other is optimized for precision aiming at longer distances. You simply look through whichever aperture suits your shooting distance and situation.
