Kel-tec RFB
One of my Fav..
Kel-tec RFB rifle is gas-operated, using short-stroke gas piston located above the barrel. Gas system is fitted with manual gas regulator, located at the front of gas block. Bolt system is somewhat unusual, as the long bolt carrier has an inverted U-shaped cross-section, and runs above the barrel and ejection chute. The bolt is hinged to the rear of the carrier. Locking is achieved by tipping the rear of the bolt down, to engage locking recesses in barrel extension. Forward ejection system includes dual extractors / ejectors, pivotally attached at either side of the bolt. Upon final stage of the bolt opening movement, those extractors are cammed up, to bring the fired cartridge above the barrel and in line with ejection chute above it. Upon closing movement of the bolt, it strips the fresh cartridge from magazine and feeds it into the chamber, simultaneously pushing the fired case forward and into ejection chute. Upon final closing movement of the bolt ejectors are cammed down to release fired case and to grip on the base of the fresh cartridge in the chamber. Fired cases then remain in the ejection chute until manually shaken out of it or pushed out by subsequent cases. Special provisions are made to avoid empty cases bounced back from chute and into receiver. Bolt system features dual return spring installed on captive spring guides. Upon disassembly, bolt group along with recoil springs is removed from the gun as one unit. Charging handle is reciprocating and can be installed on either side of the gun.The rest nof the gun is mounted on the barrel, which forms the backbone of the weapon, using four captive cross-pins. Forend, pistol grip / trigger pack / magazine housing and receiver cover / buttstock are made from impact-resistant polymer. Basic disassembly of the RFB requires no special tools other than a cartridge or other pointed object, which is used to push out connecting pins. Firing unit is hammer-fired, and features an interesting system which provides consistent and crisp trigger pull. In essence, this system keeps the sear next to the trigger, and the necessary long linkage is located between sear and hammer, not impairing the trigger pull. The trigger is fully adjustable. Manual safety levers are located above pistol grip at either side of the gun. Feed is using "metric" FN FAL magazines, which are readily available on the market. There are no open / iron sights as standard on RFB rifles; instead, a Picatinny-type rail is rigidly attached to the barrel. This rail will accept any sighting equipment with appropriate mounting interface.
