Product DescriptionThe Mission First Tactical Flip-Up Front Sight delivers reliable backup aiming for AR-platform rifles. Crafted from durable polymer, it mounts securely to a Mil-Std 1913 Picatinny rail and accepts any standard front sight post blade. Elevation adjustments are made with a standard front sight tool, with each click equaling 1/4 MOA for precise zeroing. A protective shroud shields the front post from debris and impact when folded, and its slim, rear-folding profile fits under most optics for seamless co-witness or backup use.Product Highlights Flip-up front sight with protective shroud to guard the post when stowed Lightweight polymer construction and slim profile fits under most optics Mounts to Mil-Std 1913 Picatinny rail; rear-folding design for durability Accepts standard front sight post blades; tool-adjustable elevation Precise 1/4 MOA click value for accurate zeroing Specs Construction: Polymer Color: Black Mount Type: Mil-Std 1913 Picatinny rail Folding Direction: Rear folding Elevation Adjustment: Standard front sight tool; 0.25 MOA per click Compatibility: AR-platform rifles Weight: 0.05 lb Brand Name: Mission First Tactical Manufacturer Part Number: BUPSWF UPC: 676315033103 Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
