Kel Tec RFB Riser Black RFB-750 Review

What Happened When I Tried the Kel Tec RFB Riser Black RFB-750

For those of us who meticulously configure our firearms for optimal performance, even the smallest component can make a significant difference. That’s precisely the thought that led me to the Kel Tec RFB Riser Black RFB-750. As a long-time owner and tinkerer of the RFB platform, I’ve always sought ways to refine its ergonomics and sight radius, especially for my preferred shooting disciplines. This particular riser, manufactured by Kel-Tec, promised to address a specific need: achieving a more consistent and elevated sight plane, particularly when pairing the RFB with aftermarket rail systems or when fine-tuning iron sight alignment.

My journey to this riser began on the dusty confines of a local indoor range, where my usual setup felt just a fraction off. While I could have pursued a different optic or a more complex rail extension, the elegant simplicity of a dedicated riser seemed like the most direct and cost-effective solution. Alternatives I considered included various universal Picatinny risers, but I wanted something specifically designed for the RFB’s unique profile, minimizing potential compatibility issues. My first impression upon unboxing was one of pragmatic solidity; the anodized aluminum felt robust, a reassuring sign for a component that would endure recoil and varied environmental conditions. The initial feeling was one of focused anticipation, a quiet confidence that this small piece might indeed bridge a critical gap in my setup.

Real-World Testing: Putting Kel Tec RFB Riser Black RFB-750 to the Test

First Use Experience

My initial deployment of the RFB-750 occurred during an extended range day, focusing on precision drills at distances ranging from 50 to 100 yards. I installed it atop my RFB’s factory quad rail, which, while functional, often placed my iron sights a touch too low for ideal comfort and speed. The installation itself was straightforward; the riser securely bolted into place, aligning perfectly with the existing Picatinny slots. This particular unit’s primary function is to lift your optic or iron sights, and it performed that task admirably.

During extended firing sessions, I noticed a marked improvement in my ability to acquire targets quickly and maintain a consistent cheek weld. The added height provided by this riser was subtle yet significant, reducing the need for conscious straining to align my sights. I also exposed it to a light dusting of fine range propellant residue, which wiped away easily, indicating good hard coat anodized surface integrity. There were no surprises or quirks; the riser simply did what it was designed to do, providing a stable and elevated platform for my sighting system.

Extended Use & Reliability

Over several months and numerous range outings, the Kel Tec RFB Riser Black RFB-750 has proven to be a remarkably reliable addition. It has endured regular recoil from .308 Winchester ammunition without any signs of loosening or shifting. I’ve transported my RFB in and out of various field bags, and the riser has shown no discernible wear beyond minor cosmetic scuffs on the edges from incidental contact.

Its maintenance is virtually nonexistent, requiring only an occasional wipe-down to remove dust or grime, fitting perfectly into the routine care of the firearm. Compared to some generic Picatinny risers I’ve used on other platforms, which sometimes developed play or felt less secure after repeated use, this dedicated Kel-Tec component feels far more integrated and robust. It hasn’t fallen short of expectations; in fact, it has consistently met and slightly exceeded them by providing a simple, durable solution to an ergonomic challenge.

Breaking Down the Features of Kel Tec RFB Riser Black RFB-750

Specifications

The Kel Tec RFB Riser Black RFB-750 is constructed from 6061-T6 aluminum, a standard in the industry for its balance of strength and light weight. This material choice is crucial for a firearm accessory that must withstand significant stress without adding unnecessary bulk. The riser features a hard coat anodized black finish, which not only provides excellent corrosion resistance but also offers a non-reflective surface, crucial for tactical or outdoor use.

This unit is specifically designed to mate with the RFB’s upper Picatinny rail system, effectively increasing the height of any mounted optics or iron sights. It includes a single 10-32 screw for attachment, a common and robust fastener size for accessory mounting, along with a small hex key for installation. This ensures that, right out of the box, the user has everything needed for immediate deployment, a thoughtful inclusion for a component of this nature.

Performance & Functionality

In its primary role, the RFB-750 excels. It reliably elevates your optical or iron sight line, which is essential for achieving a natural and comfortable shooting posture. For those using the RFB with its factory quad rail or similar aftermarket attachments, this riser is instrumental in bringing the sight plane up to a more accessible level.

The main strength of this riser is its focused functionality; it does one thing, and it does it very well without unnecessary frills. Its primary weakness, if one could call it that, is its singular purpose – it’s not a multi-tool or an adaptable mount. It meets expectations perfectly for its intended application, offering a stable and precisely elevated platform for improved sight acquisition.

Design & Ergonomics

The build quality of the RFB-750 is immediately apparent. The 6061-T6 aluminum feels solid in hand, with a smooth, even hard coat anodized black finish that feels durable and well-applied. There are no sharp edges or unfinished areas, which speaks to Kel-Tec’s manufacturing standards for their accessories.

Ergonomically, the riser is designed to be unobtrusive. Its profile is slim enough that it doesn’t interfere with the RFB’s overall handling characteristics. The attachment point, using the provided 10-32 screw, allows for a secure lock-up without requiring specialized tools beyond the included hex key. This thoughtful design ensures ease of use and a reliable connection that won’t compromise weapon control.

Durability & Maintenance

Given its construction from hard coat anodized 6061-T6 aluminum, the Kel Tec RFB Riser Black RFB-750 is built for longevity. For its intended use, which involves enduring firearm recoil and environmental exposure, it should last indefinitely under normal conditions. It’s a permanent accessory once installed, not a disposable item.

Maintenance is exceptionally simple. A quick wipe-down with a cloth is usually sufficient to keep it clean and presentable. There are no complex mechanisms to clean or lubricate, and no specific maintenance tips to offer beyond ensuring the mounting screw remains snug, which is easily checked with the included hex key. The inherent durability of the material and finish means there are no obvious failure points to anticipate.

Accessories and Customization Options

The Kel Tec RFB Riser Black RFB-750 comes with the essential components for its installation: one 10-32 screw and one hex key. There are no other included accessories, as its purpose is quite specific.

In terms of customization, this riser itself is not designed to be customized further. However, its Picatinny interface allows it to work seamlessly with a wide variety of aftermarket optics, red dot sights, and iron sights that also utilize the Picatinny standard. This universal compatibility ensures that you can pair it with your preferred sighting system, maximizing its utility.

Pros and Cons of Kel Tec RFB Riser Black RFB-750

Who Should Buy Kel Tec RFB Riser Black RFB-750?

This riser is an excellent choice for owners of the Kel-Tec RFB firearm who find their current iron sights or optics sit too low for a comfortable and consistent cheek weld. It’s ideal for shooters who have added aftermarket handguards with higher profile Picatinny rails or those who simply prefer a more elevated sight picture for faster target acquisition. Anyone looking for a straightforward, durable solution to improve their RFB’s ergonomics should consider this unit.

Individuals who need a highly adjustable optic mount or who are not using an RFB should look elsewhere. Those who require a more complex mounting solution, perhaps with cantilevered extensions or multiple mounting points, would be better served by a different product. For users who appreciate the Kel Tec brand’s commitment to specific firearm accessories, this riser is a complementary addition.
