If you prefer the old ways, and can shoot perfectly fine with just iron sights, you might want a decent set on your Hi-capa 5.1 GBB so you can take full advantage of the precision inherent in the platform! Introducing the Aluminium Rear Sight for Hi-capa 5.1 GBB from CowCow, a recent arrival to the Airsoft pistol aftermarket who have, thus far, blown us away with their high quality Hi-capa and AAP-01 parts!

Full description


The Aluminium Rear Sight for Hi-capa 5.1 GBB replaces the original rear iron sight on your Hi-capa 5.1 with a precisely made replacement, which is fully adjustable for both windage and elevation. The sight is can be adjusted using the two adjustment screws with the help of a small flathead screwdriver. The screw on the top of the sight controls the elevation of the rear notch, which is raised and lowered in a "tangent sight" like manner. The screw on the right side of the sight allows the rear notch to be moved left and right, compensating for any windage present. The rear face of the sight features anti-glare texturing which is intended to prevent reflected light from making the notch more difficult to pinpoint. The precise machining of this sight takes the guesswork out and does its part to ensure the sight remains set once it has been zeroed.
