First Thoughts on the Kel-Tec CNC RAIL & RISER SET FOR RFB
The Kel-Tec CNC RAIL & RISER SET FOR RFB promises to significantly enhance the functionality of the already unique RFB bullpup rifle. For under $50, this kit offers a quad rail and a front sight riser, aiming to bring the RFB into the modern tactical accessories era. As someone who has spent over a decade tinkering with and optimizing various firearms, I was keen to see if this affordable upgrade could truly unlock the RFB’s potential.
My personal motivation for seeking this kit stemmed from a desire to modernize my RFB. I felt limited by the lack of mounting options for lights, lasers, and other essential tactical gear. I had been eyeing various aftermarket solutions, and this Kel-Tec offering seemed to strike a good balance between cost and functionality.
Upon receiving the kit, the first thing I noticed was the aluminum construction of both the quad rail and the riser. The machining appeared clean, although the finish felt somewhat basic. Compared to pricier, more robust rail systems from companies like Midwest Industries, the Kel-Tec set felt lighter, but also perhaps less substantial. My initial impression was cautiously optimistic; the set seemed capable, but I remained slightly concerned about long-term durability under heavy use.
Excited to enhance my RFB, I hoped this upgrade would address my needs.
Real-World Testing: Putting Kel-Tec CNC RAIL & RISER SET FOR RFB to the Test
First Use Experience
I first tested the Kel-Tec CNC RAIL & RISER SET FOR RFB at my local outdoor shooting range. Installation was relatively straightforward, involving securing the quad rail to the barrel using the provided locking nut and set screw. The relieved top rail section for gas system adjustment proved its worth immediately, allowing easy access without removing any mounted accessories.
Performance in sunny, dry conditions was satisfactory. Mounting accessories was easy, and the added weight upfront actually improved the rifle’s balance slightly. The front sight riser brought the front sight to the correct height for co-witnessing with a rear sight, creating a cohesive sighting system. The only initial concern was a slight loosening of the set screws after approximately 50 rounds; this necessitated a quick retightening using the included hex key.
Extended Use & Reliability
After several weeks and hundreds of rounds downrange, the Kel-Tec CNC RAIL & RISER SET FOR RFB has generally held up well. There are some minor scratches on the finish, particularly around the accessory mounting points, which is typical. The quad rail remains securely attached, although I continue to check the set screws periodically.
Maintenance is straightforward; a quick wipe down with a lightly oiled cloth is sufficient. Compared to other aluminum rail systems I’ve used, the Kel-Tec set requires slightly more frequent attention to ensure screws remain tight. However, the improvement in accessory mounting capability vastly outweighs this minor inconvenience.
Breaking Down the Features of Kel-Tec CNC RAIL & RISER SET FOR RFB

These specifications offer an affordable solution to a common RFB problem. The aluminum construction helps keep weight down, while still providing a stable platform for accessories.
Performance & Functionality
The Kel-Tec CNC RAIL & RISER SET FOR RFB significantly enhances the rifle’s functionality. It provides ample space for mounting lights, lasers, foregrips, and other tactical accessories. The front sight riser effectively raises the front sight to the correct height for co-witnessing with rear iron sights or optics.
The primary strength lies in its affordability and ease of installation. A potential weakness is the need for occasional set screw tightening. It meets expectations for a budget-friendly upgrade, though it falls short of offering the rock-solid stability of higher-end rail systems.
Design & Ergonomics
The build quality is adequate for the price point, utilizing lightweight aluminum. The quad rail design allows for flexible accessory mounting at multiple positions. While the finish is utilitarian, the overall design integrates seamlessly with the RFB’s aesthetics.
There is no significant learning curve, making installation and use straightforward. The added weight upfront contributes to improved balance.
Durability & Maintenance
The aluminum construction should provide reasonable durability under normal use. Regular cleaning and occasional set screw checks are necessary for optimal performance. The anodized finish is prone to scratching, but does offer some corrosion resistance.
The Kel-Tec CNC RAIL & RISER SET FOR RFB is easily maintained with standard gun cleaning supplies. Replacing the set screws with higher-quality versions could improve long-term reliability.
Accessories and Customization Options
The kit doesn’t include any accessories beyond the necessary mounting hardware. However, it is compatible with any Picatinny rail-mounted accessory, offering extensive customization options. Lights, lasers, vertical grips, bipods, and various optics can all be readily attached.
This compatibility allows RFB owners to tailor their rifle to specific needs and preferences. The riser also permits use of aftermarket front sights.
