Allstar Tactical is running a group buy for the Century Arms WASR-10 AK-47 on our forum. These are the locap models with the narrow magwell. The magwell would have to be modified in order to fit the preban double-stack 30 round magazines. They are working on a price to have this modification done locally. The price will be $399.99 plus tax if 10 are ordered or $449.99 plus tax if 5 are ordered. The price includes shipping to your FFL or transfer to you if you pick it up in person.
The group buy ends on December 1st and details are available in the forum thread.
