How to Choose the Right Red Dot Sight for the Remington 1100
Choosing the best red dot for Remington 1100 depends on your shooting style and setup. Here’s what I recommend considering:
- Mount Type – The Remington 1100 doesn’t come with a rail. For most optics, you’ll need a Picatinny rail or SpeedBead mount. The Aimpoint Micro S-1, however, mounts directly to the rib.
- Dot Size – For hunting, 4–6 MOA is ideal. For precision slug shooting, a smaller 2–3 MOA works best.
- Weight and Profile – Keep it light to preserve the shotgun’s natural balance. Reflex-style sights under 3 oz are perfect.
- Battery Life – Look for at least 5,000 hours; ideally 20,000+. Always carry a spare.
- Durability – Shotguns produce heavy recoil. Choose sights proven to withstand 12-gauge punishment.
- Field of View – Open designs like the Holosun 510C or Burris FastFire help you maintain situational awareness.
- Warranty and Brand Support – Companies like Vortex and Aimpoint offer lifetime or long-term coverage — crucial for long-term reliability.
FAQs
1. Do I need a rail to mount a red dot on my Remington 1100?
Not always. Some optics like the Aimpoint Micro S-1 mount directly to the vent rib, while others need a Picatinny or SpeedBead adapter.
2. What’s the best dot size for a shotgun?
For bird or clay shooting, 6–8 MOA offers better visibility. For slugs or home defense, 2–4 MOA provides more precision.
3. Will recoil damage a red dot sight?
Only cheap, low-quality optics. All five picks here are tested to withstand repeated 12-gauge recoil.
4. Can I co-witness iron sights with a red dot?
It depends on the mount height and optic model. Most shotgun setups prioritize fast acquisition over co-witnessing.
5. Which is better for low light — red or green dot?
Red dots are traditional and easier to see in mixed lighting. Some Holosun models allow switching to green.
6. Is the red dot worth it for a Remington 1100 used in hunting?
Absolutely. It improves visibility, shot placement, and reaction time, especially in low-light forests.
Conclusion
If you’re looking to upgrade your shotgun’s accuracy and speed, these five optics stand out. For rib-mounted simplicity, the Aimpoint Micro S-1 is unmatched. If you prefer durability and flexibility, the Trijicon RMR Type 2 or HOLOSUN 510C are outstanding options.
