Daves might have some multicam. I talked to them a while about it but they're pricey and not the issued stuff. Rather from what I understand it's the truspec repro stuff which is probably the best you're going to get as I've heard people saying that Crye stuff is now under ITAR.
Other sites to find chestrigs and vests could be 911supply.ca, 1337tactical.com, oneshottactical.com, etc.
If you're looking for repro stuff then airsoftpark is highly recommended, I've dealt with them on multiple occasions and they always come through. Then there's sites like dragonredairsoft.com (not to be confused with another store of similar name).
