## Description

The Kel-Tec RFB is a bullpup semi-automatic rifle chambered in 7.62x51 NATO (.308 Win.). The bullpup layout puts the action behind the trigger group, which keeps overall length at 26 inches while retaining an 18-inch barrel, a meaningful portability advantage over conventional .308 rifles of similar barrel length.

### Key Specifications
- **Caliber:** 7.62 X 51 NATO (.308 Win.)
- **Barrel Length:** 18 inches
- **Action:** Semi-Automatic
- **Capacity:** 20 rounds
- **Weight:** 8.1 pounds (129.6 ounces)
- **Total Length:** 26 inches
- **Finish:** Green Receiver with Green Handguard

### Detailed Features
The receiver is 4140 steel. The barrel has a salt bath nitride coating for corrosion resistance and reduced fouling. A Picatinny rail runs along the top for optic mounting, and the safety lever sits in an intuitive position for right-handed operation.

The forward-ejection system is one of the more distinctive aspects of the RFB: spent cases eject forward through a tube rather than to the side, which makes it workable for left-handed shooters and eliminates brass raining down on a neighbor in a stall.

### Usage Scenarios
The 26-inch overall length makes the RFB notably easy to maneuver in tight spaces compared to a conventional .308 rifle, and the 20-round magazine gives adequate capacity for range sessions or field use. The 7.62 NATO chambering delivers meaningful terminal performance at distance, though the 8.1 lb. weight is something to factor in for extended carry.

## What Customers Say

*AI-generated insights from customer reviews*

The Kel-Tec RFB draws a split reaction from the firearm community. Enthusiasts who prioritize the bullpup format (shorter overall length, full-length barrel) tend to appreciate what the RFB does well: the forward-ejection system is genuinely ambidextrous-friendly, the 7.62 NATO chambering gives real stopping power, and the compact package is hard to match at this price point in a semi-auto .308.

The criticism is real, though. Trigger feel is the most consistent complaint; the bullpup linkage adds noticeable takeup compared to a conventional rifle, and some users find it less intuitive than a standard layout. Aftermarket support is limited relative to AR-10 or FAL platforms, which restricts customization. A smaller number of owners report reliability hiccups with certain ammunition types, and the conventional advice is to stick with quality brass-cased factory loads, especially during a break-in period.

Accuracy feedback is generally positive for the intended use case, inside 300 yards for most owners, but precision shooters expecting sub-MOA performance from a factory bullpup may find it doesn't meet that bar without additional work. Overall, the RFB has a dedicated following among people who specifically want a compact .308, but it rewards owners who go in with realistic expectations about trigger feel and aftermarket availability.
