Let’s Dive into Kel Tec RFB Bayonet Lug Black RFB-410
The Kel Tec RFB Bayonet Lug Black RFB-410 is a seemingly simple accessory designed to allow the attachment of a standard M9 bayonet to the Kel Tec RFB rifle. Priced affordably, it aims to add a tactical edge and historical flair to this already unique bullpup rifle. However, like many aftermarket parts, the devil is in the details, and proper fitment is key to achieving the desired functionality.
I’ve always appreciated the multi-role capability of a rifle, and the idea of adding a bayonet to my RFB intrigued me. My aim was to enhance the rifle’s CQB (Close Quarters Battle) potential and give it a distinctive look.
Upon unboxing, the Kel Tec RFB Bayonet Lug Black RFB-410 appears to be a solid piece of hardware, finished in a matte black that matches the RFB’s aesthetics. The kit includes the lug itself, a hex key, a set screw, and installation instructions, all seemingly straightforward. Compared to universal bayonet mounts that often require significant modification, this promised a direct fit, which was a major selling point. My initial reaction was cautiously optimistic, tempered by past experiences with “drop-in” parts that weren’t quite.
Real-World Testing: Putting Kel Tec RFB Bayonet Lug Black RFB-410 to the Test
First Use Experience
My first attempt at installation took place at my workbench, following the included instructions. The lug is designed to slip over the RFB’s flash hider and be secured with the set screw. However, it was immediately apparent that the lug wasn’t sitting flush against the flash hider’s rear surface. I quickly discovered what a previous user had also noted: it was designed for the older 18″ barrel RFBs.
This created a significant problem, as the bayonet mount would be unstable and prone to rattling, completely defeating its purpose. I considered shimming the lug to achieve a more secure fit, but ultimately decided against it, as this could compromise the bayonet’s alignment and potentially damage the flash hider. The initial experience was disappointing.
Extended Use & Reliability
Due to the fitment issues, I haven’t been able to properly use the Kel Tec RFB Bayonet Lug Black RFB-410 in any practical scenarios. Attempting to force the issue would likely damage either the lug, the flash hider, or both. As such, I haven’t been able to assess its long-term durability or perform any maintenance beyond wiping it down with a dry cloth.
The experience highlights the importance of verifying compatibility before purchasing aftermarket parts, even those marketed as “direct fit.” It also underscores the need for manufacturers like Kel Tec to maintain consistent specifications across production runs or clearly identify compatibility restrictions.

Performance & Functionality
When properly fitted, the Kel Tec RFB Bayonet Lug Black RFB-410 should provide a secure mounting point for a standard M9 bayonet. Ideally, it would allow for quick and reliable bayonet attachment and detachment without affecting the rifle’s accuracy or handling. However, given the documented fitment issue with newer RFB models, its performance is questionable at best.
Its primary weakness is its lack of universal fitment across all RFB models. This limitation severely impacts its usability and value for a significant portion of RFB owners.
Design & Ergonomics
The Kel Tec RFB Bayonet Lug Black RFB-410 features a simple, functional design. Its matte black finish blends seamlessly with the RFB’s aesthetics, and its low profile minimizes any added bulk. A potential area for improvement would be a more adjustable design to accommodate slight variations in flash hider dimensions.
Durability & Maintenance
Assuming a proper fit, the bayonet lug is constructed from durable materials that should withstand the stresses of bayonet use. However, the set screw, being a small component, could be prone to stripping if overtightened. Maintenance should be minimal, primarily involving occasional cleaning to remove dirt and debris.
Accessories and Customization Options
The Kel Tec RFB Bayonet Lug Black RFB-410 does not offer extensive customization options. Its sole purpose is to facilitate the attachment of an M9 bayonet. Compatibility with aftermarket flash hiders is unknown and likely to vary depending on their dimensions.
Pros and Cons of Kel Tec RFB Bayonet Lug Black RFB-410
Pros
- Provides a mounting point for a standard M9 bayonet on the Kel Tec RFB.
- Matte black finish blends well with the RFB’s aesthetics.
- Relatively simple installation if compatible with the rifle’s barrel length.
- Affordable price point.
- Potentially enhances the RFB’s CQB capabilities.
Cons

Who Should Buy Kel Tec RFB Bayonet Lug Black RFB-410?
The Kel Tec RFB Bayonet Lug Black RFB-410 is suitable ONLY for owners of Kel Tec RFB rifles with the original 18″ barrel. Those seeking to add a bayonet for historical reenactment, tactical training (with a compatible rifle), or simply to enhance the rifle’s appearance may find it appealing.
Owners of newer RFB models with 18.5″ barrels should definitely skip this product due to the documented fitment issues. A must-have modification (if one could be devised) would be a shim or adjustable mechanism to accommodate variations in flash hider dimensions.
Conclusion on Kel Tec RFB Bayonet Lug Black RFB-410
The Kel Tec RFB Bayonet Lug Black RFB-410 could be a worthwhile accessory for enhancing the functionality and aesthetics of the Kel Tec RFB rifle. Its affordable price and simple design make it an attractive option. However, the critical fitment issues with newer RFB models severely limit its appeal.
The value proposition is questionable, as the product is essentially useless without proper compatibility. I cannot personally recommend it without a major caveat: verify your RFB’s barrel length before purchasing. If Kel Tec addresses the fitment issue with an updated design, then it would become a viable option. Until then, proceed with caution.
