  • Mounts to the receiver with four screws, which means installation depends on proper fitment and secure hardware setup.
  • At 1.2" high and 1.6" wide, the low-profile design helps preserve iron sight use, but it also keeps the mounting surface compact.
  • Intended for attaching a scope or red dot; it does not add any sighting system on its own.
