### ⭐ 







  
  
    There are no screws properly sized to hold this rail.
  

*by A***R on Reviewed in the United States on September 8, 2020*

The heads of the M6 screws don't fit in the counterbores on the rails. Its actually impossible to source the right screw for this rail and it has been a huge pain. The heads of 1/4in socket head screws fit, but the threads don't.  I will probably end up needing to either grind down my m6 screw heads, use undersized screws, or drill out the rails for 1/4" screws. None of those options are ideal. Don't buy!
