I have had one Rem trigger issue and I currently have 5 700's. The one issue was with a gun assembled by Brown Precision and not touched by anyone but them. The gun fired on bolt closing on the range over sand bags twice in a row. I had hunted the gun for several years after purchase with NO issues. When we dissasambled the gun my smith buddy took the trigger apart and found a sliver of metal had peeled off the sear. He stoned the parts square again and reassembled. I have now shot the gun for another ten years with no issues.

Once a year I take all of my 700's down and clean the trigger group with a spray brake parts cleaner to keep any oil accumulation from gunking them up. I have both old bolt locking and newer model triggers and none of the x triggers. The only let off reduction have been done by professional smiths and all of the screws have been resealed with something to include nail polish.

I also clean my Ruger 77's that way once a year.

YMMV
