I am looking at the syrac purely due to the equal uniform profile and the locking option that prevents you from over tightening the set screw. My second choice would be the Seekins due to the brass locking screw, but I know my dad would crank the shit out of that brass screw and damage something.... But I am looking at the carbon fiber railed free float tube from Nordic components so I doubt I will have an issue with my grendel builds. My 300blk build might have an issue since I am going with the Aero Precision COP upper, so I am interested in people's answers too.
