How Much Is a KelTec RFB Worth? (2026 Value Update)

How We Calculate Used KelTec RFB Values

KelTec RFB value is affected by the gun’s condition, the variant or configuration, and its accessories or upgrades.

Condition and Value

The value of a KelTec RFB is influenced by its condition. The highest prices go to factory-new guns from dealers, followed by unused but preowned ones in perfect condition.

A gun profssional can appraise your gun to give you a valuation. Gun appraisal usually has a fee, but we ourselves offer it for free online.

To see how we professionally evaluate your firearm (for free) and turn that condition into a payout, view our 3-step selling process for a guaranteed FFL offer.

From there, you can estimate used Kel-Tec RFB prices using these tiers:

Like-New or Mint

• Top prices for secondhand guns
• Never fired, never marked
• Perfect form and function

Excellent

• About 10% less than mint
• Only lightly used, near-invisible wear
• Near-perfect form, perfect function

Very good

• About 20% less than mint
• Used occasionally, with a little wear
• Wear is limited, perfect function

Good

• About 30% less than mint
• Used often but cared for
• Worn but not ugly, perfect function

Fair

• About 40% less than mint
• Used often and not cared for
• Wear is unsightly, mostly intact function

Poor

• About 50% less than mint
• Beat up, scratched, dented, or rusted
• May not even work any longer

How We Appraise KelTec RFB Models

The model of the RFB affects its value. KelTec has released several over the years.

KelTec RFB Price (RFB Carbine or RFB18)

The average used KelTec RFB is worth $500 to $1,000. A new KelTec RFB sells for $1,500 to $1,845 at retail.

The carbine is the base model with an 18.5-inch barrel and 5-pound trigger. The RFB also has an adjustable gas system and is known for its forward-ejecting design.

KelTec RFB Hunter Price (RFB24)

The average used KelTec RFB Hunter is worth $600 to $1,200. A new KelTec RDB20 costs $1,800 to $2,050 at retail.

The main source of RFB Hunter value is that it packs a 24-inch barrel into a gun that’s still only 32.5 inches in length. It’s slightly heavier than the base RFB model.

This is a model that holds value well. Because it’s a premium firearm in the line, we use a secure gun shipping and buying system to ensure every transaction is fully insured and legally compliant.

How Accessories Affect What We Pay for Your KelTec RFB

If you want to sell a KelTec RFB online, you likely want to get the best price possible for it. One way to do that is to bundle it with accessories or upgrades, but this doesn’t always work.

That’s because only excellent-condition and known-brand accessories typically sell. Many buyers also prefer to buy only the firearm itself, and not things they see as extras.

Below are some accessories you may be able to bundle with your gun when selling a Kel-Tec RFB.

Original Box and Papers

Infinity Pistols ship in a hard plastic briefcase-style box with foam padding. If your box is in good shape, bundle it with the gun.

Value: Around $10 to $20 for the matching box and papers.

Spare Magazines

The RFB often ships with just one mag, so most buyers will appreciate working spares.

Value: Around $5 to $10 a mag.

KelTec RFB Hard Case

A hard case sold separately by Kel-Tec for $126 and molded specifically to fit the RFB18 and RFB24. It also has space for various accessories.

Value: Around 30% to 50% of original value.

KelTec Angled Grip

This fits a number of Kel-Tec guns, from the RFB to the RDB. It’s a good add-on for reducing fatigue, though it obviously varies by user. It’s about $28 to $31 at retail.

Value: Around 30% to 50% of original value.

RFB Bayonet Lug

Kel-Tec designed this $35.50 lug to fit the RFB rifles only. Great if you (also) want to bring a knife to a gun fight.

Value: Around 20% to 40% of original value.
