The KelTec RFB Carbine .308 Win Bullpup Rifle (KelTec part no. RFB18) is a semi-automatic rifle in a forward-ejecting bullpup layout, and RFB stands for Rifle, Forward-ejecting Bullpup. A dual-extractor system pulls each fired case from the chamber and carries it up to an ejection chute above the barrel, where it exits forward. That is what lets the rifle work equally well from either shoulder. The 18-inch barrel sits in a rifle only 26.1 inches long overall, so it stays handy in a truck, a blind or a tight room while still shooting a full-power .308 Win.

Key Specifications

• The chambering is .308 Win, a full-power cartridge with deep ammunition choices for hunting, range work and defense.
• The barrel is 18 inches, which pairs full-length ballistics with a shorter overall package than a conventional rifle.
• The bore and chamber are chrome lined, which resists corrosion and makes cleaning easier.
• The rifle is a forward-ejecting bullpup, with spent cases carried forward and out above the barrel instead of toward your face.
• Operation is short-stroke gas piston, which keeps the action cleaner than direct impingement and helps long-term reliability.
• The locking system is a tilting-block action, which gives the bullpup a conventional-rifle cross-section rather than a bulky receiver.
• The rifle accepts metric FAL-type magazines that drop free and do not need to be rocked in.
• The controls are fully ambidextrous, so a left-handed shooter can run the rifle as easily as a right-handed one.
• Overall length is 26.1 inches, as much as 14 inches shorter than other rifles with the same barrel length.
• The action is semi-automatic, with one trigger pull per shot for fast, controlled strings.

Frequently Asked Questions

Why is the RFB called forward-ejecting? Because spent cases are pulled from the chamber by a dual-extractor system and pushed into an ejection chute above the barrel, so they exit forward. That keeps the bullpup ambidextrous.

What magazines does the RFB use? It accepts standard metric FAL-type magazines, which drop free and do not need to be tilted in.

How long is the RFB carbine? It measures 26.1 inches overall with an 18-inch barrel.
