It seems logical that of all gas systems this one ought to be less sensitive to burn rates.....? For an article I talked tom one of the CMP M1 guys and he said bent op rods are not unknown but theya re not common. What he has seen more of is cracked receivers but tying that to not using IMR4895.... can't really be done.
I just remembered where I read this, it was in the Garand Collector's Journal. That ought to credible maybe not as fact but as a legit second opinion on the matter, I'd think.
