You're going to have a hard time right now w/all that's going on. I opted for a FSC556 w/YHM threads for Phantom suppressor. If you can find one I personally like them better than the YHM QD now that I've researched the two. If you can still find one of those that might be the way to go. I ordered mine from AimSurplus and he was getting more in this week. They run about $125 but worth the extra money from what I've read.
