a shame this kind of thread doesn't happen anymore.
you do realize this thread is 200 years dead and buried right?
i've heard about POF's "advanced" BCGs, but never really investigated.. i'm guessing their cam pin is basically a big bearing? if you can reduce friction between bolt and cam pin, you can reduce erosion of the cam pin/hole (play), which will reduce bolt breakage at the hole, in theory.
bolt breakage at the hole can also be reduced by consistent proper hardening.. the studies ive read about bolt breakage have shown that it takes both play AND uneven tempering to prematurely break a bolt.. but "prematurely" is the key term.
