The 68 round mid-cap mags do not feed like shit... they actually feed ALL of them perfectly.
As for not being able to import them... buy them for airsoftgi.com.... their service is amazing and shipping is really fast. The way it gets accross the boarder is they declare it as (plastic bearing holder) which by all means is not lying at all because thats exactly what they are. I got 3 KS P90 mags from them with absolutely NO issues at all.
