I don't know much about the scout, but the DSA is one sweet rifle and worth every penny.
The "FN" you were refering to, that DSA is making, is actually an STG-58 kit gun. DSA uses the best FAL blueprints, and they are Steyr blueprints, not FN.
The Austrian FAL's are superior to the Belgian FAL's, and DSA bought ALL the rights to Steyrs schematics.
The STG-58 kit guns run around $900.00-$1000.00. They are the finest of their kind. They look and shoot incredibly nice.
DSA's factory new guns, the SA-58 line, are 97% new guns, minus the stock and pistol grip. They are without a doubt the finest FAL ever made, including the original FN's and the Austrian Steyr STG-58's.
If you have an extra $1600.00 laying around, the SA-58 will blow your mind. If a $1000.00 price tag is better, then their kit guns are the best of their class by a long shot. You just can not go wrong with a DSA. Cheap mags too.
Hopefully someone can fill you in on the Springfield scouts.
You got a win/win anyway you slice it with this purchase.
