Kel-Tec RFB Features

The Kel-Tec RFB is a semi-automatic bullpup rifle chambered in .308 and is available with an 18 or 24 inch barrel.  This rifle’s unique action takes spent cases and ejects them out of the front of the rifle through an ejection tube allowing it to be fired from either shoulder without having spent brass hitting you in the face.

Kel-Tec RFB Capacity

The Kel-Tec RFB is chambered in 7.62x51mmNATO (or .308 WIN in freedom units) and uses metric-pattern FAL magazines allowing the user 10 and 20 round capacities.
The RFB weighs 8.7 pounds, about a half of a pound over the FAL, and measures 27.5 inches long.  While its added weight and rear-heavy balance may make it uncomfortable to carry over longer distances, its shorter overall length allows it to easily be maneuvered when climbing in and out of vehicles.  It also excels in close-quarter environments.

Kel-Tec RFB Ergonomics

The RFB has a charging handle mounted over the handguard on the left side of the gun while the rest of its controls are ambidextrous.  The safety is found on either side of the grip while the magazine release is located behind the magazine.  The handguard has a somewhat triangular cross-section to increase surface area for better control when firing and more comfort when carrying.

Kel-Tec RFB Fit & Finish

The RFB is built with an optics rail long enough to accept just about any scope or optics setup desired.  With iron sights, the short sight radius available would be less inherently accurate, but the rail is more than long enough to accept any magnified optics, holographic sights, or red dot and magnifier combos.
