The RFB is a truly ambidextrous 308 Win bullpup rifle. Thanks to its innovative forward ejection system, dual bolt release, left & right side safety levers and ambi magazine release, southpaws can enjoy this little powerhouse as much as the rest of us.

RFB stands for Rifle Forward-ejecting Bullpup. Designed to feed from the FN/FAL metric pattern 20-round magazine, the RFB features 7.62 power in an overall short package while still boasting an 18.5″ barrel. The RFB also redefines the bullpup trigger with a smooth pull at 5lbs and a clean break.


  • Forward Ejection
    • The unique proprietary bolt design holds dual extractors that simultaneously extract empty brass and send it down the ejection chute as the bolt reciprocates.
  • Rugged
    • Heavy duty construction is a must for a 7.62 rifle, but don’t let the 8lbs scare you. The RFB is as balanced as it is tough and we saved weight where safety would allow us.
  • Adjustable Gas
    • The RFB is equipped with an adjustable gas system that allows the user to curb recoil while maintaining reliability. This feature also makes the RFB an excellent suppressor host.
