If you are tired of the generic looking triangle sight that seems to be on every other M4 then this is the one you want. The King Arms flip up sight is a simple and inexpensive way to modify the looks of your M4. Plus, if you have optics on your gun the flip up sight in the down position will be out of sight and out of mind.
The overall construction of this sight is very good ,and looks good. I have a KWA M4. Because this sight uses set screws to hold the sight to the barrel, unlike the factory sight that uses pins, the only way to align the sight straight up and down with the gun is looking with your eyes and then tightining the set screws down. So the sight will only be as straight up and down as your eye can see holding the gun up to your face. This in my opinion is very poor for a $55.00 sight. Also the gas tube becomes to short when using the sight. And my factory side sling mount will not fit with this sight.
Very good construction, good looks, good function
*No set way to align the sight straight up and down with gun due to set screw mounting
*Shortens gas tube
*Side sling mount won't fit
