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. One 20 round magazine is included*. Barrels on current models are 18" long, with a chrome lined bore and chamber. The muzzle is threaded 5/8x24 TPI and comes equipped with our A2-style Flash Hider*. Longer barrel lengths of 24", 26" and 32" will be available in the future. 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 comes with a two point sling that can be easily configured to suit the user's preference. Available accessories include a free-floating, four-sided Picatinny forend, bipod mounts, a removable bayonet lug for use with NATO style bayonets including our own Folding Bayonet, and many more.
