I placed an order for one of Ciener's AK47 7.62x39 conversion kit in early December 2007. The checked, in the amount of 268.00, cleared my bank on Dec. 17, 2007. As of April 29, 2011, I’ve not yet received the conversion kit. Ciener’s web site indicated 30 to 120 day delivery time frame -- the 120 days have passed long ago!! I’ve tried to call Ciener’s office and I have sent emails, I’ve sent letters, I even sent a Certified letter, but no response! What a rip off!!
