Not exceptional, but adequate. - UTG Pro 870 Optic Mount, 12 Gauge

Small plates that sit behind the mount to allow for a more flush fit to the receiver are quite awkward and like to slip out during installation. Not well thought out. Shell saddle has two issues. It does not sit flush with the receiver. As a result it will snag on the front side and chew your flesh up on the back end. Additionally the shell holders themselves are not adjustable and as such over time will flex and become loose. Not a lot of alternatives out there that allow you to mount a reflex sight on your shotgun without drilling and mounting a rail. Not bad for the price point. Will most likely keep it and see how it goes.
