From the SME forum: Battlecomp on a featureless CA build?
***This is in response to: http://m4carbine.net/showthread.php?t=109661 - SHIVAN***
While the BattleComp does do a pretty good job, the legal types here in CA have recommend people not to use them on featureless rifles as they do reduce the flash some what and the law covers what the device actually does in addition to what it is called and marketed towards. As far as I know the CADOJ have not released a opinion letter regarding the matter yet.
The KAC Triple Tap is generally regarding as being safe to use, but pricey.
Here is a good list of muzzle devices and if they are safe, risky or forbidden to be used on featureless builds: https://sites.google.com/site/featur...muzzle-devices
I personally am establishing my exit strategy once my current enlistment ends.
