The most rigid handguard available. - Icon Defense AR Drive Lock Hand Guard

I use this handguard with a pec15 all the way out at the end. There is ZERO POI shift with heavy abusive use. I treat this like a tool, not a showpiece and it performs as expected. If you follow Son of Liberty on IG they have a video beating the brakes off an M89 handguard, and it still functions fine and never slips off the nut. WEll come to find out, ICON DEFENSE makes those M89 Drivelock Handgaurds for Sons! I'm Sold. Every rifle will have these on them from now on. This even comes standard with a Titanium barrel nut.
