Mossberg 500XBL 20g 24″ RS RB PORTED Review

First Thoughts on the Mossberg 500XBL 20g 24″ RS RB PORTED

The Mossberg 500XBL 20g 24″ RS RB PORTED is a replacement barrel designed to enhance the versatility of your existing Mossberg 500 20-gauge shotgun. This barrel promises improved accuracy with slugs thanks to its fully rifled bore and adjustable rifle sights, while the ported design aims to reduce recoil. Having spent years fine-tuning various shotgun setups, I was immediately intrigued by the potential for transforming my trusted Mossberg 500 into a dedicated deer-hunting platform.

My need was simple: a cost-effective way to increase the effective range and precision of my 20-gauge for deer season. I’d been using a smoothbore barrel with bead sights and while effective at close range, longer shots were a frustrating guessing game. The fully rifled bore and adjustable sights of the Mossberg 500XBL 20g 24″ RS RB PORTED seemed like the perfect solution.

Unboxing the barrel revealed a solid, well-finished piece of equipment. The bluing was even and deep, and the rifle sights appeared robust and easily adjustable. It felt heavier than my original smoothbore barrel, a characteristic I attributed to the rifling and porting.

I considered a few other options, including a cantilever-mount barrel that would allow for scope mounting. Ultimately, I chose the Mossberg 500XBL 20g 24″ RS RB PORTED for its simplicity, lower cost, and the fact that I prefer iron sights for the type of hunting I do. My first impression was positive – this barrel felt like a serious upgrade ready for the field.

Real-World Testing: Putting Mossberg 500XBL 20g 24″ RS RB PORTED to the Test

First Use Experience

My initial test took place at my local shooting range, a familiar environment where I could focus on evaluating the barrel’s performance. The weather was typical for late fall: damp and cool, with a slight breeze. I started at 50 yards, using a variety of 20-gauge slug ammunition.

The difference between this rifled barrel and my old smoothbore was immediately apparent. Groupings tightened significantly, and the adjustable sights allowed me to dial in my zero with ease. Recoil felt noticeably reduced thanks to the ported design. The first few shots were incredibly satisfying, confirming that I’d made the right choice.

Despite the improved accuracy, I did encounter one minor issue. The adjustable sights, while effective, felt a little loose. This didn’t affect performance, but I made a mental note to tighten them up before my next outing.

Extended Use & Reliability

After several weeks of use, including pre-season scouting and deer hunting, the Mossberg 500XBL 20g 24″ RS RB PORTED has proven to be a reliable and accurate performer. The bluing has held up well, showing no signs of rust or wear despite being exposed to damp conditions. Cleaning is straightforward, requiring only standard shotgun cleaning equipment.

The durability is impressive; the barrel has withstood the bumps and scrapes of the hunting trail with no issues. Compared to my previous setup, the Mossberg 500XBL 20g 24″ RS RB PORTED offers a significant improvement in accuracy and recoil management. This translates directly into more confident and ethical shots in the field.

Breaking Down the Features of Mossberg 500XBL 20g 24″ RS RB PORTED

Specifications

• Gauge/Caliber: 20 Gauge. This ensures compatibility with any Mossberg 500 receiver chambered for 20 gauge.
• Length: 24″. The 24-inch length provides a good balance between maneuverability and optimal slug velocity.
• Model: OEM. Guarantees correct fit and function with Mossberg 500 shotguns.
• Sights: Adjustable Rifle. Allows for precise zeroing and improved accuracy compared to bead sights, especially at longer ranges.
• Bore-Rifled: Fully Rifled. The rifling imparts a spin on the slug, stabilizing it in flight for enhanced accuracy.
• Finish: Blued. Provides a protective coating against rust and corrosion, while also offering a traditional, non-reflective appearance.
• Ported: Reduces felt recoil by redirecting gases upwards and outwards.

Performance & Functionality

The Mossberg 500XBL 20g 24″ RS RB PORTED significantly enhances the accuracy and range of a standard Mossberg 500 20-gauge when using slugs. The rifled bore ensures consistent slug stabilization, resulting in tighter groupings at distances beyond what’s achievable with a smoothbore barrel. The adjustable rifle sights allow for precise zeroing, eliminating guesswork and promoting ethical shot placement.

One potential weakness lies in the sight adjustment mechanism itself; it requires occasional checking to ensure screws remain tight. However, the overall performance far outweighs this minor inconvenience. This barrel meets and exceeds expectations for those seeking to transform their Mossberg 500 into a capable deer or hog hunting platform.

Design & Ergonomics

The barrel’s blued finish provides a classic, understated look that complements the Mossberg 500’s overall design. The added weight, due to the rifling and porting, contributes to improved stability during firing. The weight, combined with the reduced recoil from the porting, make for a more comfortable shooting experience.

The adjustable rifle sights are intuitive to use, even for those unfamiliar with iron sights. The design is simple and effective, with no unnecessary frills. There is a small learning curve to dialing in the sights, but the process is fairly simple.

Durability & Maintenance

The Mossberg 500XBL 20g 24″ RS RB PORTED is built to last, constructed from durable steel and finished with a robust bluing. With proper care, this barrel should provide years of reliable service. Maintenance is straightforward, requiring only regular cleaning and lubrication.

The blued finish may require occasional oiling to prevent rust, especially in humid environments. The rifling will also need periodic cleaning to remove lead and powder fouling.

Accessories and Customization Options

The Mossberg 500XBL 20g 24″ RS RB PORTED itself doesn’t come with additional accessories beyond the adjustable rifle sights. However, it’s compatible with any aftermarket Mossberg 500 accessories designed for 20-gauge shotguns. This includes sling mounts, shell holders, and different sight options (although the pre-installed adjustable rifle sights are generally sufficient).

While this barrel doesn’t offer a cantilever mount for optics, aftermarket gunsmithing options are available for those who prefer a scope. Consider a cheek riser for your stock if you plan to use optics, as the higher sight line may require it for proper eye alignment.
