Mark,
I have the DSP-5 infont of me. I do not have a copy of the DSP-83.
Date of approval / issued is 09/11/2007...Country of Ultimate Destination is "Canada" port of exit from US is "LAX" and there are "PROVISOS" which had to be met. They were met on the US side, verified, and then the guns were allowed out "APPROVED WITH PROVISOS".
Not sure who was indicated as the "End User" but I can't find it on the DSP-5 that I have.
As I said before, it doesn't seem fair that these couple were approved and so many other applications were rejected. They are cool guns and well thought out. The internals (bolt and bolt carrier) remind me of the C9 / (M249 in US speak). Nice long rail to put the scope / sight where ever you need it for eye relief.
I still think I like the FN SCAR (haven't shot one yet though) a bit better.
