Step-by-Step Installation Instructions



- Safety Check: Ensure the shotgun is completely unloaded. Check both visually and physically.
- Disassembly: Remove the barrel from the shotgun to facilitate easier installation.
- Cleaning: Clean the area of the barrel where the sight will be attached using the solvent and soft cloth to remove any residue or dirt.
- Positioning the Sight: Place the rear sight at the desired location on the barrel. Most rear sights for the 870 will sit near the end of the barrel.
- Marking the Spot: If drilling is necessary, use a marker to precisely indicate where holes must be drilled. Otherwise, align the sight according to the kit instructions.
- Drilling (if required): Carefully drill holes using the appropriate size drill bit, ensuring not to penetrate deeper than necessary.
- Securing the Sight: Attach the sight using screws provided in the kit. Apply a small amount of thread locker to each screw to prevent loosening under recoil.
- Alignment Check: Ensure the sight is properly aligned. Make any necessary adjustments.
- Reassembly and Testing: Reattach the barrel to the shotgun and conduct a safety check. Test the setup at a range to ensure proper installation.
Highlight:
Avoid over-tightening the screws, as this can strip the threads or warp the sight base.
Pro Tips and Installation Techniques
- Using a torque wrench can help ensure that screws are tightened to the manufacturer’s specifications, avoiding damage.
- A bore sight tool can be used post-installation to ensure that the sight is perfectly aligned with the bore axis.
Variations and Customizations
- Tactical Rear Sight: For a more tactical look and utility, consider a sight with additional features like ghost rings.
- Fiber Optic Sights: These can enhance visibility in low light conditions and are available as an alternative to standard metal sights.
Serving Suggestions
Once your rear sight is attached, maintaining the firearm’s cleanliness and functionality with regular cleaning and inspections will ensure it operates at its best. Pair your upgraded 870 with various accessories such as a sling or an extended magazine tube for enhanced performance and ease of use.
