Light + strong = good

I own two of these: one on 9mm carbine and one on 16,5" AR. Wanted a light and simple solution for rear sight. It has all thats needed for close to medium range sighting and nothing more. Adjustment of windage will not change by accident. Actually it's quite hard when you want to adjust it too! Have used a tip of 5.56 round to press the plunger and screwdriver to adjust the setting. I do not like the screw DD uses for tightening. The screw is quite soft and driver tends to slip unless it fits perfectly. Torx screw would be the answer. The aperture used in these is low quality. I have seen three sights and the aperture varies from awful to tolerable. The peeps are not in the center and the aperture is visibly off horizontally. Aperture can be changed afterwards. Despite all this I would recommend to buy this if flip up feature is not needed. The cons are not so remarkable.
