FMJ, Cobray, Leinad, Leinadi, Mountain Arms Corporation, SWD, WDA, and a few other names have were(or are) "sock puppet" and "dummy/holding corporations" for Sylvia and Wayne Daniel.
They were one of the biggest names in the mass production of the Ingram/MAC type guns, and they're also largely responsible for giving these guns a bad rep.
They're also the ones that did the MAC-10 ad that read "The Gun that made the 80's Roar".
Because of their advertising, the price point of their models, and the liberal media's hyperbole surrounding "sub-machine guns," "assault pistols and rifles", and "semi-auto killing machines", Wayne and Sylvia have also been sued several times by private individuals, cities, states, and even the Feds. They've also been the subject of an untold number of witchhunts.
Currently, both Wayne and Sylvia have residences in Copperhill TN. Wayne still has a machining facility and small warehouse operation where some of the various kits and parts are still made.
I grew up 15 minutes from Copperhill, and can say that Wayne and Sylvia were both very nice people, and they had a good reputation locally for the way they treated local people and customers. In fact, up until 2002, the Leinad business was listed in the local phone book.
While many people deride their customer service and quality, I somehow doubt that the number of people who spread these stories have ever owned one of their products, much less extensively shot them. Out of the people I've known who owned their firearms, overwhelming most were happy with the product, price, and customer support.
Example:
I know someone who bought an M11/9 from them that developed problems after the buyer used some Israeli "+P+ type" rounds which were marked specifically for use in rifles and carbines only. The guy was out of state, and he was exceptionally p.o.'d- p.o.'d to the point of being obnoxious and irrational. Wayne paid for shipping of the gun both ways, had his best machinist go through the gun, perform an action job, and then sent it back to the customer. The key was that the customer actually contacted Leinad and got them involved. Many of the people who have problems with these guns take them to a local gunsmith without much experience in dealing with these arms and then manages to screw them up worse than before- making a bad situation worse. There is something to be said for OEM's in some cases.
Anyway, I know this is an old post, just thought I'd throw in my two cents
