I ordered the parts at 2AM last Saturday and they were at my door this morning at 9AM. I got me 2 spare mags (wanted these for a long time), 2 connectors which are where the transfer port is incorporated(ah yes mod time), a regulator (I'm going to put some better springs in it and orings) and a couple spare gauges because a lot of SPA guns use these gauges. It was $103 shipped, yes the shipping isn't cheap, I think the next time I order parts from SPA I'll load up on lego parts (probably mostly PR900W parts for some needed tinkering I requested the China post but they won't do it anymore, only Fedex from what Julie told me.
You need an FFL license to order barrels direct from China, they won't ship stocks because they don't want to chance breaking them I guess. Rob my order came Fedex, they won't ship Chinapost anymore for parts probably cause people complained about how long it took. Fedex only takes about a week from China, they're very fast but expensive.
