A shotgun punishes an optic in a way a rifle does not: a short, heavy recoil impulse that loosens fasteners and finishes off lesser electronics. Everything on this page is chosen with that in mind — large-window open reflex sights, sealed micro dots supplied without a mount so they can go straight onto a receiver plate, the Warne 6108M rib mount that carries a reflex sight over the barrel of a vented-rib gun, and the Streamlight TL-Racker forend lights that replace the fore-end of a Remington 870 or Mossberg 500/590 outright. Whether you shoot practical shotgun, keep a pump gun for vermin, or simply want both eyes open on a moving target, this is the shotgun end of our range in one place.
Mounting matters as much as the sight itself — see our red dot sight mounts and Warne scope mounts. For the wider ranges browse red dot sights, enclosed red dot sights, Holosun optics and weapon lights. We have also written up the best red dot sights for shotguns if you want the reasoning behind these choices.
Frequently Asked Questions
Will a red dot sight survive shotgun recoil?
The mount and its fasteners matter as much as the optic. Fit to a solid receiver plate or a rib mount, torque to the manufacturer's figures, use a thread locker, and check your zero again after the first fifty rounds. A sealed or fully enclosed emitter is worth having on a gun that lives outdoors.
Why buy the version without a mount?
The Trijicon MRO SD and MRO HD are listed both with AR-height mounts and as No Mount versions. On a shotgun you almost always want the No Mount option, because the height you need is set by your rib mount or receiver plate rather than by a co-witness with AR iron sights.
