Trijicon RMR is the gold standard for micro pistol reflex sights, and it just happens to also work on offset rifle mounts, lightweight PCCs and shotguns. It's durable, small and effective sighting system for tactical shotguns.
Improved Accuracy - Highly recommend 3 MOA dot or bigger for better dot clarity and effective coverage for shotgun pellet
Long Battery Life - Just 1 CR2032 battery can last as long as 3.5 years on medium dot brightness setting
7075 Rugged - Super rugged body construction that can take a brutal beating in the field and still stays on
Built For Handgun Recoil - Much tighter battery grip to survive handgun slide G force, which means it works on a hard recoil shotgun without shifting the zero.
Pros
- Small and lightweight
- Very durable glass and outer body to resist impact stress
- New design lengthens battery life up to 3.5 years
- Tighter battery grip than Type 1 model
Cons
- Sight removal required for battery swap
- Open emitter design can attract dirt and debris
Aimpoint Micro is the best red dot sight for many carbine setups, and it works well on shotgun platforms because it's small, lightweight, recoil proven and long lasting
Improved Accuracy - Highly recommend 3 MOA dot or bigger for better dot clarity and effective coverage for shotgun pellet
Accepts Various Mounts - So many aftermarket mounts available for this optic. Recommend low mount for shotgun cheek weld height
7075 Rugged - Super rugged body construction that can take a brutal beating in the field and still stays on
Enclosed Emitter Body Construction - Unlike the RMR, the Aimpoint Micro is fully enclosed to keep debris out of the optic to work under rain and mud splash with a simple finger wipe to clean it off
Pros
- Small and lightweight
- Fully protected emitter to keep debris out
- Very durable glass and outer body to resist impact stress
- Battery lasts up to 5 years
- Tighter battery grip than Type 1 model
Cons
- Sight removal required for battery swap
- Open emitter design can attract dirt and debris
Vortex Venom is the entry level micro red dot sight for 12GA shotguns, and it works as good as the Burris FastFire 3 and it provides a very clean glass quality with edge to edge clarity for competition and skeet range use
Improved Accuracy - Highly recommend 6 MOA dot or bigger for better dot clarity and effective coverage for shotgun pellet
Accepts Various Mounts - So many aftermarket mounts available for this optic. Recommend low mount for shotgun cheek weld height
Almost Invisible Lens Frame - Thin lens frame makes it almost invisible around the edges to give the shooter max situational awareness when focusing the eyes on the target
Pros
- Small and lightweight
- Recessed MOA turrets to prevent accidental adjustment
- Recommended for skeet shooting
- Top battery loading without sight removal
Cons
- Bluish lens tint may not be good for indoor use without a weapon light
- Open emitter design
- Super slim lens frame
