Review on Upgrade Your Shooting With Feyachi'S 45 Degree Offset Iron Sights - Rapid Transition Backup Front & Rear Sight Set For Picatinny/Weaver Rails by Bill Maki

The front sight did not make it through the first day at the range. I got theses as backup sights and I did not expect to be overly impressed by sights that cost under $30. However, I did expect them to hold up long enough to actually use them at least once. The front sight just hangs there. It will not lock into place in either the up or down position. The rear sight is locked in the down position and will not move because the button you depress in order to raise the sight up is stuck and will not depress. I could not recommend these sights for use on any firearm.
