I have taken my evo out to the range twice since I have installed your handguard (which I love) and both times I end up having to cut my trip short early because the bolts are backing out of the clamp block and allowing the whole thing to slide off.

Do I need to torque this down to a specific setting or do I need to use locktite?

If I have to use locktite is blue enough?

1.  Make sure the 8 bolts holding the forend to the mounting block are LOOSE

2.  Torque down the two bolts that pinch the block around the barrel.  Yes, blue loctite is fine.  There is not a set torque value (most people don't have inch lb torque tools so we do not specify.

3.  now tighten down the 8 exterior screws

4.  After a range trip or two make sure the bolts are still tight

Let me know if that takes care of it.
