MPN: BUPSWF
The Mission First Tactical Back Up Polymer Flip Up Front Sight with standard elevation adjustment (BUPSWF) mounts directly to any 1913 Picatinny rail and accepts any standard front post blade compatible with iron sight configurations. This backup sight is engineered as a co-witness or secondary aiming system for AR platforms and tactical rifles equipped with primary optics, delivering reliable point-of-aim when electronic systems fail or require a transition to iron sight zeroing.
A proprietary polymer shroud design protects the front post blade from debris accumulation and impact damage when the sight remains deployed in the down position. Standard adjustment increments equal ¼ MOA per click—the industry norm for precision rifle zeroing—requiring only a standard front sight tool for elevation correction. The slim profile keeps the sight stowed beneath most magnified and red-dot optics without interference, maintaining a clean upper receiver profile. Mission First Tactical fabricates the sight housing using reinforced polymer engineering optimized for reliable cycling and extended field service without excessive weight penalty.
This backup iron sight serves law enforcement, military, and civilian operators who demand redundant aiming capability on duty rifles and precision platforms. It's particularly suited to configurations where primary optics are mission-critical but iron sight backup is mandatory—patrol carbines, entry weapons, and modular rifle builds where reliability hierarchy matters. The flip-up design allows rapid deployment without removing the primary sight system, addressing the need for quick transition during malfunction scenarios or during zeroing verification drills.
Backup iron sights have become standard accessories on tactical rifles over the past two decades, particularly in professional duty environments. Mission First Tactical's BUPSWF represents the polymer-shrouded category—a balance between traditional steel irons and lightweight alternatives, optimizing for durability and debris resistance in austere conditions while maintaining the sub-ounce weight profile operators demand on precision builds.
