The first thing I did when I got my scar was install a dead air brake and timed it off the jam nut that comes with the scar 17. About 700 rounds later almost all suppressed, I have read NOT to use the jam nut for muzzle devices for suppressors. The alignment checked out with the kba rod on my nomad...
Long story short I have had zero issues with this setup, the muzzle device has never come loose, I didn't use any thread locker either.
Are there any other concerns that could come about?
Thanks

Here are pics of the scar with the normal L suppressor and kba alignment rod, I couldn't get a great top down center pic, so here are a left and right. Looks to be concentric.
