I havn't had any issues with the screws in my low-recoil .223 but the rear screw on my .30-06 has been loose after every trip to the range. The front may have been a little loose as well but not enough to notice when re-tourqeing. I did spray some CLP on the threads before i re-installed them after doing the trigger mod. I did this because the bolts in my blued .223 appeared to be lightly oiled and these were dry so i figured they could used some preservative. I don't think it is possible that i over-tourqued them with the cheap chinese hand driver i am using. I use one hand and don't over-do it.

Would it be a bad idea to put some blue loctite on these screws? I don't plan on taking the stock off again unless something breaks or it gets submerged in water.
