M87 utg picatinny rail on 870 express - Leapers UTG Remington 870/1100 Picatinny Claw Mount

Item showed up 4 days after order. Do my PO it takes an extra day so it was only 3 days after order including the weekend. Should have been a 5 minute job to install. The front screw did not want to catch the threads on the mount probably spent 25 minutes on that one. I believe the screw was slightlt warped turning it and wiggling the mount finally got the threads to connect. Hard to turn from the first turn on. End of bolt was jagged as well. So it could require a little patience. Minimal rub on receiver finish from putting it on alignment issue 10-12 times. Optics Planet provided a flawless transaction once again. They are 100% with me once again.
