Rifle Forward-Ejecting Bullpup (RFB)

RFB stands for Rifle, Forward-ejecting Bullpup.

Why forward-ejecting?

It allows the RFB to be the first truly ambidextrous 7.62 NATO Bullpup ever developed. The patented, dual-extractor system maintains control of the case from the moment it leaves the magazine and upon firing, pulls the fired case from the chamber and lifts them to push them into an ejection chute above the barrel, where they exit.

The Bullpup configuration and tilting-block mechanism allow the 18-inch model to be only 26.1 inches long, or as much as 14 inches shorter in overall length than its competitors with equal barrel lengths. Furthermore, the stock and mechanism cross-section is similar to a conventional rifle, in stark contrast to existing Bullpup rifles.

Safety

The RFB is also one of the safest Bullpups ever developed because the breech is separated from the shooters face by two layers of 1.6 mm steel. In the highly unlikely event of a case rupture, gas expansion is directed downwards through the magazine well to protect the shooters head and face.

Construction

The RFB is a short-stroke gas piston operated semi-automatic rifle in 7.62 mm NATO caliber. It accepts standard metric FAL type magazines which work “drop free” and do not need to be tilted in. Barrels on current models are 18 inches and 24 inches long, with Salt Bath Nitride Finish in the bore and chamber. All of the barrels are now SBN (Salt Bath Nitride) for finish as it will last longer than the previous chrome-lining finish and the bolts are now finished with Titanium Nitride to assist with the smoothness of operation.

The muzzle is threaded 5/8x24 TPI and comes equipped with Kel-Tec’s A2-style Flash Hider, except the Hunter Variant which comes with a thread protector.

All controls are fully ambidextrous; the reciprocating operating handle can be switched to either side. The trigger mechanism is second to no other Bullpup ever built and better than nearly all commercial semi-auto rifles. The safety disconnects the trigger and blocks the hammer action. A Mil-Spec Picatinny rail is attached rigidly to the barrel.

No open sights are provided, allowing the user to select from the very best new optics and sight systems available.

The RFB also comes with a two point sling that can be easily configured to suit the user’s preference.

Available accessories include a free-floating, Quad Rail Picatinny and Sight Riser, bipod mounts, a removable bayonet lug for use with NATO style bayonets including Kel-Tec’s own Folding Bayonet, Stock Spacers for added length, and a Tactical Operation Handle.
