    Purchased for Colt LE6920. When I push bottom piece forward to latch onto the front cap and then tried to lift the back end up to fit onto the barrel nut two wing on the side would not clear the teeth on the milspec barrel nut. Those wings curve inward and so they do not freely slide over either side of the teeth on the barrel nut. There is no way to push bottom part in place. Maybe some installation video might be help from FAB- DEFENSE to show how they install this handguard to AR 15 rifle?
