What Makes Rob Roberts Gun Works 200290 Biz Raptor Invector 20 Gauge 17-4 PH Stainless Stee Stand Out?
In the world of shotgun chokes, finding one that truly enhances performance with specific ammunition types can feel like searching for a needle in a haystack. The Rob Roberts Gun Works 200290 Biz Raptor Invector 20 Gauge 17-4 PH Stainless Stee choke promises to be that solution, specifically designed to optimize the performance of bismuth shot in a 20-gauge shotgun. It hails from Rob Roberts Gun Works, a name synonymous with innovation and quality in the shotgun world.
I was looking for a choke specifically designed for bismuth, as I’ve been transitioning away from lead for waterfowl hunting on protected lands. Traditional chokes often don’t pattern bismuth shot as effectively, leading to inconsistent results.
My initial impression upon unboxing the Rob Roberts Gun Works 200290 Biz Raptor Invector 20 Gauge 17-4 PH Stainless Stee choke was its robust construction. The 17-4 PH stainless steel felt substantial and durable, a clear indicator of its quality.
Compared to standard Invector chokes or even extended ported chokes I’ve used, the Biz Raptor has a unique internal geometry. This design promised a tighter, more consistent pattern specifically with bismuth, unlike the generic performance of other chokes. My usual modified choke just wasn’t cutting it with the bismuth loads I was trying.
My first impression was excitement, tempered with a healthy dose of skepticism, as I’ve heard many performance claims before that didn’t pan out. I was eager to get this choke to the range and see if it truly lived up to the hype and lived up to what I needed to take my shotgun to the next level when using bismuth.
Real-World Testing: Putting Rob Roberts Gun Works 200290 Biz Raptor Invector 20 Gauge 17-4 PH Stainless Stee to the Test
First Use Experience
I tested the Rob Roberts Gun Works 200290 Biz Raptor Invector 20 Gauge 17-4 PH Stainless Stee choke at my local shooting range, using a variety of 20-gauge bismuth loads. I patterned the loads at 30 and 40 yards, the typical distances I encounter while duck hunting.
The performance was noticeably improved compared to my previous modified choke, even in slightly windy conditions. The patterns were denser and more uniform, especially with the bismuth loads it was designed for.
The choke was simple to install and remove with a standard choke wrench; no specialized tools were needed. There was a very slight learning curve with recognizing the patterns it produced.
After the first use, I was impressed with the consistent patterns but curious about its long-term durability and performance in harsher weather conditions. I could tell after seeing the patterns it was producing that it would be a game changer when I got out in the field, however.
Extended Use & Reliability
After several weeks of use, including a few duck hunting trips in varying weather conditions, the Rob Roberts Gun Works 200290 Biz Raptor Invector 20 Gauge 17-4 PH Stainless Stee choke has held up exceptionally well. There are no signs of wear or corrosion despite exposure to water and mud.
The 17-4 PH stainless steel construction has proven to be highly durable. The choke still looks and performs as new after cleaning.
Cleaning is straightforward with standard gun cleaning supplies and a choke tube brush. No special maintenance has been required.
Compared to my previous experiences with standard chokes, the Biz Raptor noticeably improved my hit ratio with bismuth loads, especially on longer shots. It delivers on its promise of optimized bismuth performance, and it has certainly become a staple of my shotgun.
