I know those sights came on the gun, but I'm not a fan of that type of apertures.
I have a set around here somewhere similar to those and they just weren't doing it for me.
I have found that the Command Arms flip sights are much better. Especially at 100 yards or less, which is where you'll probably be using this carbine most of the time.
These have more of a straight line point from a lack of better description and the front post being more straight up than curved, fits within the rear sight channel which helps line the gun up on the shoulder to the target quickly.
I have added them to the smg and also the bullpup sks and can't see myself taking them off.
