that your RFB will provide many years of faithful and reliable service.

Description

The rifle, Forward-ejecting, Bullpup (RFB) is a lightweight, air-cooled, gas operated, semi-

automatic, forward ejecting, Bullpup-type rifle which feeds 7.62x51mm NATO cartridges

from metric FAL style, self contained, detachable, steel, box type magazines. It is totally

ambidextrous, uses a tilting bolt locking mechanism, and a short-stroke gas piston to

actuate the bolt carrier.

Construction

The RFB is a revolutionary design utilizing aircraft quality components made on state of the

art CNC machinery. Every single aspect of the design has been thoroughly tested to

ensure the utmost in reliability, function, and ease of use.

The RFB has a medium weight barrel made of 4140 Chrome-Molybdenum ordinance grade

Steel, with a chrome-lined bore and chamber in lengths of 18”/457mm and 24”/610mm is

available. The rifling rate of twist is 1 turn in 11.25 inches/285.75mm. All barrels come

threaded to accept 5/8

–24 TPI muzzle accessories and 18” models come equipped with an

A2-style compensator except where prohibited by law.

All sheet metal components are made of aircraft quality 4130 steel. The bolt and receiver

are made of 4140 steel. The gas system on the RFB is made of 4140 steel and internally

plated. It is designed to be low maintenance and be corrosion resistant.

CAUTION: After firing several rounds the exposed metal surfaces forward of the top cover become very hot and can cause painful burns. Use caution when handling. Wait at least one hour for the metal components to cool before attempting disassembly. Ammunition Use The Kel-Tec RFB is designed and chambered for the 7.62x51 NATO Cartridge ONLY. The Caliber is listed on the left side of the rifle above the magazine well. Do not use any other ammunition.

and other substances known to cause birth defects, reproductive harm, and other serious physical injury. Have adequate ventilation at all times. Be sure to wash hands thoroughly with soap and COLD water after any amount of exposure. How the RFB works A loaded magazine is inserted straight up, not tilted, into the rifle’s magazine well until a “click” is heard. Maintenance and Care of your firearm All firearms require periodic maintenance to ensure safe and reliable functioning.

Figure 7: DO NOT RIDE THE CHARGING HANDLE! Release it at its rear most point. Figure 5: Bolt is lifted upwards by the carrier to unlock the action Charging allows the bolt to push a round out of the magazine and into the chamber while simultaneously cocking the internal hammer. The base of the magazine should then be soundly smacked with the palm of the hand to ensure proper seating. The shooter must then load the rifle by pulling back on the charging handle and releasing it.
PAGE 9
Figure 9: As the bolt moves forward, it pushes the round out of the magazine When the bolt has traveled to its forward most position the bolt’s rear will be pushed downward against a flat bearing surface inside of the receiver called the shoulder. The Extractors on the bolt will then slide downward over the rim of the chambered round and grasp it firmly.

Figure 15: As the bullet passes the gas orifice in the barrel, burning gas enter the gas system Figures 13: The trigger mechanism in the rear position The pressure will very rapidly increase inside of the gas system even as it begins to vent out of the front of the gas head. The gas will begin to push the short stroke piston rearward. By this time, the bullet has long made its exit from the rifle’s muzzle.

brass to come into contact with the ejection chute ramp while simultaneously pushing the next round in the magazine forward out of the magazine and into the chamber. The empty brass continues forward through the ejection chute and out the ejection opening out through the ejection opening in the gas block. Figure 17: The Extractors pull the fired case from the chamber The bolt is now free to travel backwards with the bolt carrier.

magazine to be used. Insert the magazine into the magazine well with a firm upward thrust. A tilting action is not required to seat the magazine into the RFB. Using the palm of your hand, give the magazine’s floor plate a firm smack and then a gentle tug to guarantee the magazine is fully seated. Figure 21: The extractors are down, the hammer is cocked, and the rifle is again ready to fire.

design itself has long since shown its age. The magazine, however, is still very good and the ubiquitousness of this type of magazine ensures that they will be available for a very long time at very low prices. These magazines have been made in a dozen countries or more over the last half century and as a consequence they vary widely in their dimensions and specifications.

Figure 29: Gas Restrictor Cap set for suppressor use. This will reduce pressure in the system enough to allow proper functioning without excessive recoil on operating components. NOTE: When using a suppressor with the RFB, it will be necessary to perform cleaning operations and basic maintenance more frequently. Avoid use of Subsonic Ammunition in the standard RFB when using a suppressor. See note in the warning section of this manual.

Figure 33: After the pins are pulled out, slap the back of the pistol grip to open the assembly Now, remove the top cover and buttstock assembly by firmly grasping the buttstock and pulling straight off. Figure 35: Pull the charging handle back until it aligns with the slot in the handguard to remove it Grasp the receiver and the Bolt Carrier Assembly with one hand, pull the Charging Handle out with your free hand as shown in figure 37.
PAGE 16
Now pull the Bolt Carrier Assembly past the Grip Mount to remove it from the rifle. Figure 39: Grasp the barrel with one hand and pull down the handguard Figure 37: Once the charging handle is removed, pull out the carrier assembly The Rear Assembly Pins may be pushed back into their housing, keeping the assembly from closing. The hammer may prevent a cleaning rod from entering the chamber if the Rear Assembly Pins are aligned with the holes in the receiver as when the rifle is assembled.

Figure 41: Pull the ejection chute forward to remove it Removing the Bolt from the Carrier Group The Bolt Carrier Group may be disassembled into its individual components for periodic maintenance and cleaning. After the Bolt Carrier Group has been removed from the rifle during field stripping, the Bolt Camming Pin may be pushed out from the right side using the nose of a dummy cartridge. No further disassembly of the carrier group is necessary or advisable.

aligned with the slots on the Extractors. Any further Extractor disassembly or maintenance should be conducted only by an experienced Armorer or Gunsmith. Clean and lightly lubricate all surfaces of the Bolt and Bolt Carrier Assembly in order to maintain proper functioning. Reassemble Bolt Carrier Group in reverse order. Be certain to have the extractors in the lowered position in order to hook the top of the bolt into the carrier. The cam pin may then be pressed in to hold the bolt.

Figure 48: Wiggle the piston to remove Warning: Never fire your RFB with the Gas Piston Removed or improperly installed. Failure to properly install the Gas Piston may result in serious injury. Ensure that the gas ring is in good shape and not excessively worn. It will be necessary to replace this ring every 3-5 thousand rounds. A one-piece gas ring designed for the AR-15/M-16 rifle will fit. The Gas restrictor cap must also be removed for periodic cleaning.

Slide the Top Cover over the Bolt Carrier Group and Receiver. Pull out the Rear Assembly Pins to their open most position. Slightly compress the Recoil Springs by pressing against the Butt on the Top Cover and close the grip assembly. Look to see that the holes of the Grip Assembly, Top Cover, and Receiver are fully aligned and push in the Rear Assembly Pins. Cycle the action to verify proper function. The rifle is now assembled.

Trouble Shooting Guide: Problem: When I pull the trigger, the hammer does not release. Possible Cause: Disconnector is stuck down. Solution: Disassemble the rifle and ensure that the Disconnector is not damaged or blocked by debris. Use compressed air to clean trigger group of dust and obstructions. Problem: When firing, the bolt and carrier will not return to battery because it’s “stuck open”. Possible Cause: Rifle has double fed. Solution: Select a different magazine.
PAGE 22
Possible Cause 1: The magazine follower is too short to activate the bolt stop. Solution 1: Select another magazine. FAL magazines have a wide variance in tolerance and not all magazines will function properly in every firearm. Possible Cause 2: Gas System is adjusted too low. Solution 2: Adjust the Gas System Regulator clockwise one position. Load one round into a magazine and insert it into the rifle. Chamber round and fire. Repeat adjustments until bolt locks open consistently.
