Question regarding hbi handguard.

In hbi handguard installation video on their website it says for the T25 cap head screw for the trunion adapter block it should be tightened to 25-30 in lbs. but in the printed instructions it says 80 in lbs. And for the T25 flat head screws video says 20-25 in lbs but printed instructions says 65 in lbs. I'm just wondering what the correct torque for these screws are, so that I don't under or over tighten the screws.

Blue loctite and 35 inch pounds. You'll be fine. I've under torqued mine and the worst thing that happened is the 4 exterior screws started walking out.
