Lets see...
DSA receiver- Machined from forged steel, using orgional Austrian (a FN licencee) blueprints.
Entreprise receiver- Cast, (with known problems of porosity in castings) reverse engineered, no FN blueprints. Known problems with ejector block installment, and bad reciever geometry on reciever feed rails.
POS in my book,
(and many others, do a search on the FAL Files)
After many hours of work, and much blood, tears, toil, and sweat Ive got the Entreprise running like a raped ape, and the exterior finish machining on the one Entreprise Ive got is actually nicer than my last DSA, but hey, ever see the exterior finish machineing on a real FN?
While Imbel recievers MIGHT be "better" than DSA (hammer forged from FN licencee vs billet forged from non-FN licencee) I'd rather have the rest of the parts built by a country that I can drink the water in.
I actually should thank Entreprise, the 2 years I spent trying to get their reciever to run taught me a lot, and started my current obsession with the rifle.
