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.   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.
