I've been looking lately and would like to hear from a few who own them.
Since you're not getting subsonic from them what cans are you going with? I've looked at the specwar k and it seems like the go to but I've also thrown the idea around of getting one of the short AAC cans as well to keep the added length as minimal as possible.
I'm using a 16" midlength right now but am debating changing it to a 14.5" carbine.
Also, would you say forget the 556 can and get a 762 instead? I'm not shooting anything other than 556 right now and don't plan on buying a 300blk or anything else anytime soon.
