They were imported before the ban and most came without the auto sear. However I have personally seen preban with the auto sear just like I have seen AK47 kits with ALL the full auto parts in them. The auto sear can be removed and the gun is legal in my opinion.
They are no harder on brass than any other 308 semi automatic when they have the correct parts in them. Mine had an incorrect spring and this resulted in about a half dozen bent cases before the spring was changed. I can now run a hundred or two thru it and there are no bent rims on the cases. Its kinda like having a 5 year old change plugs in your Vette. He can probably get the job done but you may have a cross threaded spark plug or two. The gas system can be adjusted to drop the cases on the bench right beside the gun or you can throw them out 30 feet and spend an hour looking for them. Mine handes any jacketed bullet I care to put in the magazine without an issue. I personally would not use unjacketed bullets in my FAL but then again thats me.
They are no more inaccurate than an M1A or Garrand. Barrel must be timed correctly and this is done quite easily and any 6 year old could do it. The "Gear" receivers are the best but the DS arms run a close 2nd. Either of these fits and goes together with a minimum amount of trouble.
The recoil with the same rounds is less than other semi-automatics and this is due to the superior gas recoil system.
