Key Features
- Forward Ejection System – Spent cases are routed down a chute away from your face, making this bullpup safe for left- and right-handed shooters without any conversion.
- Adjustable Gas System – Tune the action for different loads or add a suppressor without over-gassing the rifle. This keeps recoil manageable and reliability high.
- Fully Ambidextrous Controls – Safety selector, magazine release, and charging handle work from either side, so you never have to break your grip.
- 20-Round Magazine Included – Comes with one factory 20-round magazine, giving you serious firepower right out of the box.
- Bullpup Design – Full 18-inch barrel in a package shorter than most carbines, making it easier to maneuver in tight spaces.
Who It's For
This rifle is for shooters who want a compact .308 platform without sacrificing barrel length or accuracy. It fits home defense, hunting, and range use equally well. New gun owners will appreciate the ambidextrous controls, and experienced shooters will like the adjustable gas system.
Pros and Cons
- Pros: Compact bullpup length, forward ejection works for lefties, adjustable gas system, reliable with .308 and 7.62 NATO, includes 20-round magazine.
- Cons: Trigger pull is heavier than some AR-10 triggers (around 7.5 lbs per Kel-Tec specs), and the forward ejection chute can be blocked if you mount accessories too far forward.

FAQ
Is the Kel-Tec RFB18 reliable with all .308 ammunition?
Yes, the RFB18 handles both .308 Winchester and 7.62 NATO reliably. The adjustable gas system lets you tune the action for different power levels, and Kel-Tec recommends breaking it in with 150-grain FMJ before switching to match loads.
Can I mount a scope on the RFB18?
Yes. The receiver has a full-length Picatinny rail, so you can mount any standard scope or red dot. Just be careful not to block the forward ejection chute with a very large objective lens or a flashlight mounted too far forward.
Does the RFB18 come with a warranty?
Kel-Tec backs the RFB18 with a one-year warranty against defects in materials and workmanship. For details, check the manual or contact Kel-Tec directly.
How do I clean the forward ejection system?
Field stripping is straightforward. Remove the bolt carrier group, pull the barrel, and wipe down the ejection chute with a cloth and solvent. Kel-Tec recommends lubricating the chute lightly to keep cases moving smoothly.
