CYMA Flip-up Iron Sights for 20mm Picatinny Rail

If you're looking for flip-up iron sights to finish off your build, the CYMA Flip-up Iron Sights for 20mm Picatinny Rail are ideal. The set includes the front and rear sight and both mount to 20mm Picatinny rails. Windage and elevation are fully adjustable via the dials on each sight and the rear sight offers two apertures for aiming; a fine aperture for bright conditions and accurate semi-auto fire and a wider one for low-light and full auto mayhem.
