NcStar VMARFLC Pro Series AR-15 Flip Up Iron Sights Set Black

The NcStar VMARFLC Pro Series Flip Up Front and Rear Sights deliver reliable backup sighting capability for AR-platform rifles when primary optics fail. These spring-loaded iron sights deploy instantly with the press of a button, ensuring shooters maintain target acquisition in critical situations.

What Makes This Different

Unlike fixed iron sights that obstruct optic sight pictures, the VMARFLC Pro Series features a low-profile folded position that co-witnesses with red dot sights and magnified optics. The precision-machined aluminum construction provides consistent zero retention through thousands of deployment cycles. Both front and rear sights incorporate positive locking mechanisms that prevent accidental folding during recoil.

Key Features

• Spring-loaded flip-up mechanism deploys with single button press
• Machined 6061-T6 aluminum construction with Type III hard anodizing
• Standard A2-style front sight post with elevation adjustment
• Dual aperture rear sight with 0.070" and 0.200" peep holes
• Picatinny rail mounting system fits all MIL-STD-1913 rails
• Low-profile folded height clears most optic configurations
• Windage adjustable rear sight with audible clicks

Field testing demonstrates consistent 2-3 MOA accuracy at 100 yards when properly zeroed, making these sights suitable for defensive applications and competition backup roles. The robust spring mechanism functions reliably in temperatures from -20°F to 140°F, while the hard anodized finish resists corrosion in marine environments. Competition shooters appreciate the quick transition capability when primary optics fail during timed events.
