Kel Tec RFB Review: Worthy Bullpup?

by Dave Chesson

April 2, 2022



In this Kel Tec RFB review, we’ll be covering what we think of the RFB rifle, its pros and cons, and its specifications. We’ll also provide some extra resources to help you decide whether the RFB is the right Bullpup rifle for you.

Kel Tec RFB Specs

  • Barrel Length 18″
  • Caliber 7.62×51 NATO
  • Sights Rail Mounted
  • Action Semi-Auto
  • Overall Length 26’’

Kel Tec RFB Background

Kel Tec are known for producing futuristic looking weapons, and the Kel Tec RFB is no exception. But aside from its video game like aesthetic, is the Kel Tec RFB actually a good bullpup rifle to own? And what is the purpose behind Kel Tec releasing this particular bullpup rifle?

Kel Tec’s stated aim in releasing the RFB is to offer a truly ambidextrous bullpup rifle that is easy to operate. It has been designed to be suitable for both left and right-handed shooters. 

Although most modern bullpup rifles are ambidextrous, and the RFB is no exception, one of the biggest complaints for left-handed shooters is the rearward location of the ejection port due to the bullpup design. This often shoots ejected brass into, or very near to, the shooter’s face.

One of the unique designs of the RFB is that it ejects the brass out the front of the rifle. That’s right…out the front. We’ll cover this more in our KelTec RFB review below.

Kel Tec RFB Features

1 Forward Ejection Chute

The RFB’s forward facing ejection chute prevents the side ejection problems that come with other similar weapons.

2 Ambidextrous Magazine Release

The Kel Tec RFB can be operated by left or right handed shooters alike.

3 MIL-SPEC Picatinny Rail

You can fit sights and other upgrades to your RFB with this Picatinny rail.

Kel Tec RFB Review – Our Take

The Kel Tec RFB is, well, weird.

Like some other things Kel Tec, it is a novel concept executed poorly.

That may sound harsh, and maybe it is. However, we think Kel-Tec is on the cutting edge of unique firearm designs, and we hope that they never quit. However, their end-result products sometimes seem to be an afterthought. On paper, they might seem like the best idea ever, but in your hands, they sometimes feel… well… cheaply constructed.

As a bull pup rifle, the RFB has some merits. It is lighter weight than some other options (we’re looking at you IWI X95) and it really nails the “space-gun” look.

The really novel part about the RFB rifle is the forward-ejection… this just doesn’t exist on any other commercially available rifle.

As you know from our Gun 101 series, there are 8 cycles of function for most firearms. One of the functions that is responsible for a large proportion of malfunctions is “ejection” whereby the spent casing is moved away from the firearm to make room for the next round of ammunition to feed into the chamber. For newbies, ejection is what causes the empty brass to fly out of the side of a firearm.

With the Kel Tec RFB, however, the empty cases aren’t ejected out of a side ejection-port like most rifles (because the RFB doesn’t have a side ejection port!). Instead, the empty cases are pushed down a tube above the barrel until they reach the end of the handguard where they fall out and to the ground.

It is really… different… to witness. It almost appears as if brass is falling out of the end of the barrel.

So, for ingenuity, A+. However, for execution, D-.

Why the low grade? We already covered that many malfunctions on rifles are due to ejection, and this forward ejecting system of the RFB complicates the process. Furthermore, it also blocks your easy access to the working mechanism of the rifle to manually clear the malfunction – or, for that matter, even see what the problem is (or if the gun is loaded).

Other common sources of malfunction in rifles are from failing to feed the round into the chamber and failing to extract. The RFB’s design also causes an issue in diagnosing and correcting these other potential issues as well.

Although the ejection port might be a complaint for some, for the rest of us, it is an easy way to see what’s going on with a malfunction and to clear it.

The rest of the Kel Tec RFB: The trigger is on par with a mil-spec trigger (not good), there are no options for aftermarket grips, buttstocks, nor foreends, and the accuracy is good enough for a battle rifle, but we wouldn’t call the RFB rifle accurate.

Takeaway: if you’re looking for a novel/unique space-age-looking gun, you should check out the RFB. However, if you are looking for a more reliable and serious duty bull pup rifle, you’d be better suited with the IWI X95.

Something about this gun just feels like a concept-rifle or a prototype.

Other Bullpup Rifles of its Class to Check Out

In our opinion, there’s just so much more out there than the KelTec RFB when it comes to bullpup rifles. Don’t get me wrong. I love the way they look and some of the progressive thinking that KelTec has. I just think they fell a bit short when it came to the RFB. However, there are some other seriously nice options available.

If you’re looking for something a bit heavier, check out IWI’s Tavor SAR. The SAR is actually standard Israeli military issue, but we can get a civilian-approved version of it. It’s tried and true on the battlefield and has even won a Golden Bullseye back in 2014. Either way, we’d definitely choose this over the RFB… READ MORE

  1. >”The really novel part about the RFB rifle is the forward-ejection… this just doesn’t exist on any other commercially available rifle.”

    It’s hard to take a 2022 bullpup review seriously if you’ve never even heard of, let alone reviewed, the DT MDRX which is the obvious direct comparison to this gun (also can be chambered in 308 or 6.5, forward eject and easy swap of ejection side is a big feature). I’d hoped to see those contrasted in this review, the KT is somewhat cheaper though still a pricey item. It would have been enlightening to see two FE 308 bullpups directly compared :(.

  2. Mr. Roy Chesson, what part of 7.62×51 do you not understand?
    All your ratings below is compared to WUT? High end .22s?

    RELIABILITY – Yes, the gun works well, but if there’s a problem, you’re screwed. = C
    Your one (1) gun test verdict was not buy a jury of its peers.
    ACCURACY – Decent accuracy = B
    Did you Break-in (seasoning) the barrel?
    CUSTOMIZATION – No options = D
    A bullpup is CUSTOMIZED a rifle, by design.
    ERGONOMICS – Feels ok, but no options to improve = B
    If it is OK, there are no improvement/s to be determined.
    VALUE – Better options for the money = C
    This doesn’t even make sense to me “)

  3. There is another rifle with forward ejecting cases and it was designed, built, sold, etc before the RFB. The FN F2000/FS2000 ejects shells in the exact same way as the RFB. FN started designing that rifle in 1995 and it was released to the US market in 2001.

  4. I never understand the reliability comment from the article. Why a ‘C’ if you have not had an issue yet based on “what ifs”? That is like saying,” that big guy over there has not committed a crime yet, but if he beats the murder you, you are screwed”. I have not heard of anyone having feeding problems like some AR’s. Maybe you should have a separate reliability breakouts like, “Range Test Performance” and “Long term Maintenance & Accessibility”. Reliability can be construed too many ways.
