Or Advanced Armament Corp (AAC) has a tool if one wants to get fancy.I mentioned in an earlier post that it would be good to fine a much less expensive alternative to that $40 tool. After a long while I decided finally to search for one, in case anyone (like me) wants to get fancy but doesn't want to shell out almost $50.
Thorsden Customs sells an interesting little one that sells for only $10 (+ $4 to mail it). I ordered one and will report back, in case anyone else is interested:

The above tool is designed ideally for the subbier old GI type M16 three prong, but I don't know yet that it won't work fine with this Grendel flash suppressor. I don't imagine that very much torque is actually needed.
Additionally, Surefire also sells a wrench (socket?) for their own make of three-prong flash suppressors. It may also work fine with these new low-profile Grendel FSs. And it's also just $10:
