This:
The third gen version has a mechanical lock that prevents the handguard from sliding off - a small steel piece that they are calling the "torque plate." Still not my first choice, but should be fine.

Thanks. The torque plate looks like a good idea. Now I know what that open space on the bottom is for. As far as the adhesive goes, lots of handguard so use some form. Lots of folks recommend using lock-tight on fasteners (which is a type of adhesive) so I don't see the problem in adding a little insurance to make sure everything stays in place.
This question should probably be asked in the tech sec but I'll ask here since we are on topic: would red (high strength) lock-tight work on the barrel nut instead of the supplied adhesive?
Adhesive on a Handguard is basically a workaround for bad engineering IMO. Do not compare this to fasteners. Apples and oranges. The adhesive is so these types of hand guards don't loosen up with such a short/small surface area of barrel nut.
Other rails provide ample surface area to fix this (NSR), OR in the case of the KMR for instance, provide and superior mounting method. I don't glue my guns together. But whatever.
These are supplied with green much stronger than red. We have run them without any of it at all in testing and had very good results. We included it so when these are installed they would be installed in a way that there is little doubt there is a chance of moving .The torque plate is a very big improvement for the hand guards . This part is made of 4140 and is much stronger than most of the others mentioned for anti rotation and it makes installation almost stupid proof . We have a satisfaction guarantee and a lifetime warranty . If companies like BCM and FNH use them do you think they are any good ? Nuff said.
