KEL Riser for RFB - Precision Tactical Rail Mount Adapter$21.10
Availability: In Stock
The KEL-TEC RFB is a capable rifle, but its stock handguard setup limits your ability to mount modern tactical gear. The KEL Quad Rail & Riser Set solves that problem by giving you a true Picatinny rail platform where you need it most. This two-piece kit includes a machined aluminum quad rail that wraps your barrel with 360-degree mounting real estate, plus a front sight riser that integrates seamlessly with your receiver's top rail—opening the door to optics, lights, lasers, and iron sight combinations that just weren't possible before.
The quad rail is machined from 6061-T6 aluminum and fastens to the barrel via a simple locking nut and set screw system. The design includes a relief cut in the top rail that preserves access to your RFB's gas system adjustment—no need to tear down your setup every time you want to dial in the dwell. Paired with that, the included front sight riser also made from 6061-T6 aluminum bolts directly to the quad rail, bringing your front sight interface up to the same height as your receiver rail so iron sights sit in the same optical plane.
If you shoot an RFB and have been frustrated by the lack of modern accessory mounting options, this kit transforms the rifle into something far more adaptable. Whether you're building a designated marksman setup, adding white light for low-light hunting, or simply want proper iron sight geometry for patrol-ready versatility, this is the foundation that makes it all work. It's a straightforward, no-fuss upgrade that respects the RFB's design while giving you the flexibility modern shooters expect.
