To my knowledge, Century doesn't build these rifles - they import them, and then swap out enough parts to make them 922(?) compliant - in this case, the pistol grips, and fire control parts, to give a US parts count... A recent copy of the shotgun news should reveal a couple of dwindling sources - if you have someone who'll do FFL transfers for you - if not, they sometimes can help locate a dealer in your area that'll do it for a fee... Off the top of my head, I'd say SOG, J&G Sales, Wholesale Gun, etc... You might also check gunbroker...
My SAR-1 is a Century gun, and had a little trigger slap, but I cured it myself - other than that, there weren't any major issues... With a little TLC, it cleaned up into a fine looking weapon, and has been reliable, and more accurate than I thought an AKM could be... So, I guess you could say I'm happy with MY Century rifle...
