I was doing some chrony work with 7 gun/upper combinations last evening and a had a catastrophic failure with my RFB. I was running perfectly with 168gr .308 but when I switched to 145gr it was giving me FTEs and mangled case mouths. Apparently the jams had managed to bend back the lips of the ejection chute's spring taps (which prevent ejected rounds from sliding back into the gun) to the point where they were interfering with the dual recoil springs. It looks like on the final shot both the springs were stuck forward (it may have happened one spring at a time over the course of a few jams) and I had an unsprung bolt hit the rear of the gun (called the top cover plate weldment) bulging the steel and knocking the recoil pad back about 1/4". The spot welds all held. Bent metal but I'm OK.
I will never complain about the weight of the gun again. There is a reason they put a lot of steel in the top cover plate.
