Same here, that's why I asked. Every video I've seen on torqueing a Grendel down for accuracy says 50 lbs +. Ashe, I was ecstatic too and also a little surprised. I too figured that another 1/20th revolution would equate to nearly double the torque. Considered bumping it up and backing off a little at a time up to 50 ft lbs. My other AR's I've assembled had FF tubes that didn't require timing the gas tube. They had proprietary nuts that took a lot of torque and seemed to be built a lot stouter than the mil-spec nut which I've not used previously. I definitely don't want my receiver hard bent! Think I'll stop while ahead and shoot the thing if 32 ft lbs is sure considered safe/GTG. Thanks for the feedback
