Cory Schoonover's Review of FAB Defense Top Mounted Deployable Rear Sight

Way too loose on the standard rail I have. There was nothing that I saw in the description for me, that said it would not fit a standard picatinny rail. But it doesn't fit the rail of my CMMG Resolute Complete Upper.
Pros:
  • Pricing is fair
Cons:
  • Much too loose to fit a standard picatinny rail
Best Used for:
  • Not sure
Would Recommend: No
