    How tight should the SDN6 lock up to the muzzle device? I notice with mine on my 5.56 SBR it ratchets down tight with the tuning fork. On my .308 it doesn’t tighten up all the way with the muzzle brake. It’s not really loose but it does have a little wiggle.

    its a slight difference in the mount. try polishing shoulder of the one its not locking up tight on until it locks up tight.

    I also had a similar problem. I sent my flash hider back to a AAC and they inspected it and replaced it at no charge. Great customer service!
