The Remington 870 shotgun is a legendary firearm, renowned for its reliability and versatility. Adding a slug barrel significantly expands its capabilities, transforming it from a short-range bird-hunting tool into a capable long-range deer hunting or home-defense weapon. However, effective shooting at longer distances requires accurate aiming, necessitating the addition of a scope. This guide explores everything you need to know about 870 slug barrels with scope mounts, covering compatibility, selection, installation, and more.
Understanding the Remington 870 and Slug Barrels
The Remington 870's design allows for easy barrel changes, making it a popular choice for those who need versatility. A standard 870 barrel is optimized for shot, while a slug barrel is designed specifically for shooting slugs – solid projectiles, unlike the pellets in a shotgun shell. Key differences between a standard barrel and a slug barrel include:
- Rifling: Slug barrels are rifled, meaning they have grooves cut into the barrel's interior. This imparts spin to the slug, increasing accuracy and range. Standard barrels are smoothbore.
- Sight Radius: Slug barrels often have a longer sight radius, further enhancing accuracy.
- Weight: Slug barrels tend to be heavier, aiding in stability and recoil management.
Choosing the right slug barrel is crucial. Consider these factors:
- Barrel Length: Longer barrels generally provide increased accuracy and velocity, but can be less maneuverable. Common lengths range from 18.5 inches to 28 inches.
- Gauge: Ensure the barrel matches the gauge of your shotgun (12 gauge is most common for slugs).
- Material: Most slug barrels are made of steel or steel alloys. High-quality steel is crucial for durability and accuracy.
- Manufacturer: Several reputable manufacturers produce 870 slug barrels, including Remington, Hastings, and others. Look for well-established brands with positive reviews.
Selecting the Right Scope Mount for Your 870 Slug Barrel
The scope mount is the crucial link between your barrel and your scope. Improper mounting can lead to inaccurate shots or even damage to your firearm. Here’s what to consider when choosing a mount:
- Mount Type: There are two primary types of mounts: base mounts which attach directly to the barrel and rings which then hold the scope. Some barrels come with integrated scope mounts, saving you a step.
- Material: Steel or aluminum are common choices. Steel is more durable, while aluminum is lighter.
- Height: The height of the mount determines how high the scope sits above the barrel. Choose a height appropriate for your scope and to avoid cheek weld issues.
- Mounting System: Ensure the mount is designed for your specific barrel. Some mounts use Weaver or Picatinny rails. Others directly attach to the receiver.
- Zeroing: Adjustable mounts allow for precise zeroing of your scope.
Common Scope Mount Types:
| Mount Type | Description | Pros | Cons |
|---|---|---|---|
| Receiver Mount | Attaches directly to the receiver of the shotgun. | Secure, generally a good base for other parts | Can limit barrel choices |
| Barrel Mount | Attaches directly to the barrel. | Simpler, direct mounting | Less stable than receiver mounts |
| Picatinny/Weaver Rail Mount | Uses a rail for modularity. | Extremely versatile, adds additional options | More components, adds weight |
Installing Your 870 Slug Barrel and Scope Mount
Safety First! Always unload your shotgun before performing any maintenance or modifications.
The process generally involves:
- Removing the Existing Barrel: Follow the manufacturer's instructions for safely removing the existing barrel. This usually involves pushing out the barrel pin.
- Installing the Slug Barrel: Slide the new slug barrel onto the receiver and secure it with the barrel pin.
- Attaching the Scope Mount (If Necessary): If your barrel doesn't come with a pre-installed mount, carefully attach it according to the manufacturer's instructions. Proper torque is critical to prevent damage.
- Mounting the Scope: Mount the scope in the rings, making sure it’s securely fastened.
- Zeroing the Scope: This is essential for accurate shooting. Use a target at varying distances to adjust your scope's point of impact to match your point of aim.
Note: Consult your shotgun's manual and the instructions for your specific slug barrel and scope mount. Improper installation can damage your firearm or compromise safety.
Choosing a Scope for Your 870 Slug Barrel
Choosing the right scope is just as important as choosing the right barrel and mount. Consider these factors:
- Magnification: A variable magnification scope (e.g., 3-9x40) is ideal, offering versatility for close and long-range shots.
- Reticle: Choose a reticle suitable for your hunting style and conditions. A simple duplex reticle is a good starting point.
- Objective Lens Diameter: A larger objective lens gathers more light, beneficial for low-light conditions.
- Eye Relief: Sufficient eye relief is crucial for comfortable and safe shooting.
Case Study: A Successful 870 Slug Setup
One user reported significant improvement in accuracy with a Remington 870 equipped with a 20-inch Hastings slug barrel and a Nikon Prostaff 3-9x40 scope mounted using a Warne Maxima receiver mount. This setup provided reliable performance at ranges up to 100 yards.
Conclusion
Adding a slug barrel and scope to your Remington 870 significantly enhances its versatility and long-range accuracy. By carefully selecting the correct components and following safe installation procedures, you can transform your shotgun into a powerful and precise hunting or home-defense tool. Remember to prioritize safety and consult your firearm's manual and the instructions provided with your accessories.
