The flip-up part of the sight is solid and works nicely. However, the design is just bad. The 3 set screws were a recipe for disaster as they receive unequal torque when tightened, which is what happened and the steel cracked on mine after being installed a few weeks. Also, the gas tube pin is very tight to put in and may get damaged doing so. Just not an overall good design and this made me stay away from MI for the future. VLTOR makes one that is designed better and I just installed it.
